Description
- The present invention relates, in general, to preventing erosion of downhole tools positioned within a wellbore that traverses a subterranean hydrocarbon bearing formation and, in particular, to downhole tools having a shape memory alloy integrated therein to provide erosion resistance.
- Without limiting the scope of the invention, the background will describe surface controlled, subsurface safety valves, as an example.
- Surface controlled, subsurface safety valves are commonly used to shut in oil and gas wells in the event of a failure or hazardous condition at the well surface. Such safety valves are typically fitted into the production tubing and operate to block the flow of formation fluid upwardly therethrough. The subsurface safety valve provides automatic shutoff of production flow in response to a variety of out of range safety conditions that can be sensed or indicated at the surface. For example, the safety conditions include a fire on the platform, a high or low flow line temperature or pressure condition or operator override.
- During production, the subsurface safety valve is typically held open by the application of hydraulic fluid pressure conducted to the subsurface safety valve through an auxiliary control conduit which extends along the tubing string within the annulus between the tubing and the well casing. Flapper type subsurface safety valves utilize a closure plate which is actuated by longitudinal movement of a hydraulically actuated, tubular piston. The flapper valve closure plate is maintained in the valve open position by an operator tube which is extended by the application of hydraulic pressure onto the piston. A pump at the surface pressurizes a reservoir which delivers regulated hydraulic control pressure through the control conduit. Hydraulic fluid is pumped into a variable volume pressure chamber and acts against the piston. When, for example, the production fluid pressure rises above or falls below a preset level, the control pressure is relieved such that the piston and operator tube are retracted to the valve closed position by a return spring. The flapper plate is then rotated to the valve closed position by a torsion spring or tension member in conjunction with fluid forces.
- In conventional subsurface safety valves of the type utilizing an upwardly closing flapper plate, the flapper plate is seated against an annular sealing face, either in metal-to-metal contact or metal against an annular elastomeric seal. In one design, the valve seat and the upwardly closing flapper plate each having a sealing surface with a matched spherical radius of curvature. That is, the valve seat is a concave spherical segment and the sealing surface of the flapper plate is a convex spherical segment. In this arrangement, the spherical radius of curvature of the concave valve seat spherical segment is matched with the spherical radius of curvature of the convex spherical segment which defines the sealing surface on the flapper plate. The matching spherical surfaces are lapped together to provide a metal-to-metal seal along the interface between the nested convex and concave sealing surfaces.
- It has been found, however, that even when using spherical sealing surfaces leakage may occur. Specifically, erosion of the concave valve seat spherical segment caused by an erosive stress may result in the loss of the ability to create a seal between sealing surfces. These erosive stresses include moving fluids and erosive agents such as particulate matter. Therefore, a need has arisen for an erosion resistant material that can be used for the sealing surfaces of a subsurface safety valve. Additionally, a need has arisen for such an erosion resistant material that can withstand erosive stresses such as moving fluids and erosive agents without exhibiting erosive wear.
- The present invention disclosed herein comprises a downhole fluid flow control device and method for minimizing erosion that utilize an erosive resistant material for sealing surfaces. In particular, the erosion resistant material comprises a shape memory alloy that is capable of withstanding erosive stresses such as moving fluids and erosive agents without exhibiting excessive erosive wear.
- In one aspect, the downhole fluid flow control device includes a downhole surface subjectable to an erosive stress which may be a moving fluid or an erosive agent, for example. A shape memory alloy is integrated with the downhole surface in order to provide erosion resistance by reversibly transforming between an austenitic phase and a martensitic phase in response to the application of the erosive stress. Further, the shape memory alloy reversibly transforms from the martensitic phase to the austenitic phase in response to the application of heat.

The specific embodiments discussed herein are merely illustrative of specific ways to make and use the invention and do not delimit the scope of the present invention.
- Referring initially to
FIG. 1 , an offshore oil and gas platform performing completion operations is schematically illustrated and generally designated 10. Asemi-submersible platform 12 is centered over a submerged oil andgas formation 14 located belowsea floor 16. Asubsea conduit 18 extends fromdeck 20 ofplatform 12 towellhead installation 22 includingblowout preventers 24.Platform 12 has a hoistingapparatus 26 and aderrick 28 for raising and lowering pipe strings such ascompletion string 30. - A
wellbore 32 extends through the various earthstrata including formation 14. Acasing 34 is cemented withinwellbore 32 bycement 36.Casing 34 has been perforated atformation 14 to createperforations 38 using perforatingguns 40 which have been released into the rat hole ofwellbore 32. Thereafter,completion string 30 has been lowered to locate a sandcontrol screen assembly 44 proximate toformation 14 such that a pair ofseal assemblies 46 can isolate production fromformation 14. Uphole of sandcontrol screen assembly 44 is a cross-over 42 that allows for a treatment operation within the production interval atformation 14 such as a gravel pack, fracture stimulation, frac pack or the like. Uphole ofcross-over 42 is a fluidloss control valve 48 that prevents the loss of fluid from withincompletion string 30 toformation 14 during completion operations to other formations (not pictured) uphole offormation 14. - Also depicted within
completion string 30 is atubing test valve 50 that allows for the periodic pressure testing ofcompletion string 30 during installation thereof.Completion string 30 also includes a plurality of landing nipples, such aslanding nipple 52, which is used to receive, for example, wireline set tools such as permanent and temporary bridge plugs as well as other types of flow control devices. A slidingside door valve 54 is also depicted withincompletion string 30. Slidingside door valve 54 may be used to selectively permit and prevent fluid communication between the interior ofcompletion string 30 and the wellbore annulus.Completion string 30 includes one or more subsurface safety valves, such assafety valve 56, that prevent out of control well conditions from traveling to the surface. - Many of these completion tools, as well as numerous other downhole tools such as drilling tools and production tools, may utilize downhole components having shape memory materials, such as shape memory alloys, phase changing ceramics and phase changing polymers, for example, integrated at wear surfaces. For purposes of explanation and not by way of limitation, however, the shape memory material will be presented as a shape memory alloy. As an example,
crossover 42 is subjected to significant volumes of high velocity slurry during treatment operations which commonly result in erosive wear. Utilizing a shape memory alloy of the present invention for these wear surfaces, however, minimizes or prevents such erosive wear. Likewise, the other components through which the slurry is pumped are also subjected to the erosive stress. Accordingly, fluidloss control valve 48,tubing test valve 50, slidingside door valve 54,subsurface safety valve 56 as well as numerous other valving and flow control devices may utilize shape memory alloy components to minimize or prevent erosive wear, whether the erosive wear is caused by an erosive agent, such as particulars, or friction between components, for example. By way of example, these other devices may include blast joints, sand screens, nozzles, chokes, wear surfaces of vanes, pump pistons, turbine blades, flow straighteners, flow mixers, internal mandrels, barrel slips, flow diverters, shifting sleeves, collets, snap rings, c-clamps on ball valves, landing nipples, poppets, rotors, bearings (e.g., bearing surfaces in journal bearings and thrust bearings), races, slickline wires, tubulars or venturis. As will be explained in further detail hereinbelow, the shape memory alloy components of the downhole tools resist erosion by reversibly transforming from an austenitic phase to a martensitic phase in response to the application of the erosive stress. Rather than wear, shape memory alloy components absorb the stress erosion by reversibly transforming or reversibly transitioning phase. - Referring next to
FIG. 2 , offshore oil andgas platform 10 is depicted during production operations. Disposed withincasing 34 and extending fromwellhead 60 is aproduction tubing 40. During production, formation fluids enterwellbore 32 throughperforations 38 ofcasing 34 and travel intoproduction tubing string 40 through sandcontrol screen assembly 44 towellhead 60 that is installed ondeck 20.Wellhead 60 includes numerous valves such aslower master valve 61 andupper master valve 63 which provide redundant surface isolation. Additionally,wellhead 60 includes awing valve 65 andswab valve 67. Aflowline 69 connectswellhead 60 tovessel 71 wherein production fluid brought up fromformation 14 may be processed. Many of surface production tools may utilize the shape memory alloys of the present invention. For example, in addition to the valves described hereinabove,flowline 69 andvessel 71 may utilize the shape memory alloy of the present invention at wear surfaces such as elbows or other transition regions. Other oilfield equipment that may utilize the shape memory alloys include casing valves, stabbing valves and pump jack components, for example. In addition, various downhole production tools may also benefit from the shape memory alloy of the present invention such asdownhole choke 73,downhole turbine 75,gas lift valve 77, landingnipple 79,subsurface safety valve 56 and the like. Further, although completion and production operations have been depicted inFIGS. 1 and 2 , it should be appreciated that the shape memory alloy of the present invention may be utilized with components of drilling operations as well. - Referring now to
FIGS. 3A and 3B ,subsurface safety valve 56 is illustrated in further detail.Safety valve 56 has a relatively larger production bore and is, therefore, intended for use in high flow rate wells.Safety valve 56 is connected directly in series withproduction tubing 40.Control conduit 62 provides hydraulic control pressure tolongitudinal bore 64 formed in the sidewall of thetop connector sub 66. Pressurized hydraulic fluid is delivered through thelongitudinal bore 64 into anannular chamber 68 defined by acounterbore 70 which is in communication with an annular undercut 72 formed in the sidewall of thetop connector sub 66. Aninner housing mandrel 74 is slidably coupled and sealed to thetop connector sub 66 by aslip union 76 andseal 78, with the undercut 72 defining an annulus betweeninner mandrel 74 and the sidewall oftop connector sub 66. - A
piston 80 is received in slidable, sealed engagement against the internal bore ofinner mandrel 74. The undercutannulus 72 opens into apiston chamber 82 in the annulus between the internal bore of aconnector sub 86 and the external surface ofpiston 80. The external radius of an uppersidewall piston section 84 is machined and reduced to define a radial clearance betweenpiston 80 andconnector sub 86. An annular slopingsurface 88 ofpiston 80 is acted against by the pressurized hydraulic fluid delivered throughcontrol conduit 62. InFIGS. 3A-3B ,piston 80 andoperator tube 94 are fully extended with the lower shoulder ofoperator tube 94 engaging an annular face ofbottom subconnector 106. In this valve open position, areturn spring 96 is fully compressed. - In the illustrated embodiment, a
flapper plate 98 is pivotally mounted onto ahinge sub 100 which is threadably connected to the lower end ofspring housing 102. Avalve seat 104 is confined within a counterbore formed onhinge sub 100. The lower end ofsafety valve 56 is connected toproduction tubing 40 by abottom sub connector 106. Thebottom sub connector 106 has acounterbore 108 which defines avalve chamber 110. Thus, thebottom sub connector 106 forms a part of the valve housing enclosure.Flapper plate 98 pivots aboutpivot pin 112 and is biased to the valve closed position byspring 114. In the valve open position as shown inFIGS. 3A-3B , the spring bias force is overcome andflapper plate 98 is retained in the valve open position byoperator tube 94 to permit formation fluid flow up throughtubing 40. - During operation, when an out of range condition occurs and
subsurface safety valve 56 must be operated from the valve open position to the valve closed position, hydraulic pressure is released fromconduit 62 such thatreturn spring 96 acts on the lower end ofpiston 80 which retractsoperator tube 94 longitudinally throughvalve chamber 110.Flapper closure plate 98 will then rotate throughchamber 110 to effectuate the valve closure. Further, it is necessary to have a complete seal betweenflapper closure plate 98 andvalve seat 104, which is subjected to considerable erosive stress in the form of upward moving fluids having particulate matter.Valve seat 104 includes a sealingsurface 116 having integrated therewith a shape memory alloy of the present invention in order to resist erosion by absorbing the erosive stresses and reversibly transforming phases. - Referring next to
FIG. 4 , therein is depicted the sealing elements of a valve that is generally designated 120.Valve 120 has valve closure member shown as aflapper closure plate 122, which has a convex flapper closureplate sealing surface 124. Additionally,valve 120 includes avalve seat 126 which has concave valveseat sealing surface 128. It should be appreciated thatconcave sealing surface 128 ofvalve seat 126 has a radius of curvature that is substantially equal to that of convex flapper closureplate sealing surface 124. As previously discussed,valve seat 126 includes a shapememory alloy layer 130 in order to resist erosion and maintain the radius of curvature necessary to create an effective seal with flapper closureplate sealing surface 124. - While a particular type of flow control device has been described with respect to
FIG. 4 , it should be appreciated that the shape memory alloys of the present invention may be used with other types of valves. For example, the shape memory alloys of the present invention may be utilized with back-pressure valves, ball valves, check valves, circulation valves, equalizing valves, foot valves, frac valves, gas-lift valves, gate valves, isolation valves, orifice valves, poppet valves, reverse-circulating valves, sliding sleeves, standing valves, traveling valves, tubing-retrievable safety valves and wireline-retrievable safety valves, for example. Use of the shape memory alloys of the present invention as the wear surfaces of any of these flow control devices will provide for shape memory effect and superelastic responses to impingement of sand or other particulate matter, thus providing increased wear-resistance. - Referring now to
FIG. 5 , therein is depicted a stress-temperature phase diagram 150 illustrating phase transitions of the shape memory alloy of the present invention. The x-axis is temperature (T) and the y-axis is stress (σ). In general, shape memory alloys are metallic alloys that exist in two phases and display both thermal and mechanical memory. By way of example, a titanium nickel (TiNi) shape memory alloy is represented in each of the crystal lattice structure phases. It should be appreciated that other shape memory alloys are within the teachings of the present invention. For example, the shape memory alloy may include titanium carbon-titanium nickel (TiC—TiNi) composite alloys, copper zinc (CuZn) alloys, copper zinc aluminum (CuZnAl) alloys, copper zinc gallium (CuZnGa) alloys, copper zinc tin (CuZnSn) alloys, copper zinc silicon (CuZnSi) alloys, iron platinum (FePt) alloys and the like. Additionally, the shape memory may include tribological engineering materials such as nickel (Ni)-based and cobalt (Co)-based tribo-alloys. - An austenitic phase, depicted as
austenite 152, is a high-temperature phase in which the shape memory alloy displays a high-symmetry, usually cubic crystal lattice structure. The martensitic phase is a low temperature phase in which the shape memory alloy displays a low-symmetry, monoclinic variant crystal lattice structure. As a low-symmetry lattice structure, martensite includes several variants such asdetwinned martensite 154 and twinnedmartensite 156. A martensitic phase transformation characterizes the phase transformations between martensite and austenite. As those skilled in the art will appreciate, the martensitic phase transformation includes a shear-dominant diffusionless solid-state phase transformation that occurs by nucleation and growth. More specifically, the martensitic phase transformation possesses several well-defined characteristics. The phase transformation is associated with an inelastic deformation of the crystal lattice that results from a cooperative and collective motion of atoms on distances smaller than the lattice parameters. Accordingly, the phase transformation is substantially instantaneous and characterized by an absence of diffusion. Both phases of the shape memory alloy, however, can coexist during the phase transformation. An invariant plane having well defined mutual orientation relationships, which are alloy specific, partitions the phases from one another. - As illustrated in the stress-temperature phase diagram, the austenite-to-martensite phase transformation occurs once the free energy of martensite becomes less than the free energy of austenite at a temperature below a critical temperature T0 (not illustrated) at which the free energies of the two phases are equal. The phase transformation does not begin exactly at the critical temperature T0, however. In the absence of stress, the phase transformation begins at a martensite start temperature, denoted
M 0s 158, which is less than T0, and continues to evolve as the temperature is lowered until a martensite finish temperature, denotedM 0f 160, is reached. - Similarly, when the shape memory alloy is heated in the absence of stress from martensite, the martensite-to-austenite phase transformation begins at a austenite start temperature, denoted A0s 162, and the material is fully austenite at an austenite finish temperature, denoted A0f 164. Hence, the martensite-to-austenite transformations exhibit a hysteresis and a dependence on the direction of the temperature change. Moreover, the difference between the transition temperatures is related to the critical temperature, T0, which may be approximated as follows:
(M0s+A0f)/2 - Shape memory alloys exhibit the shape memory effect during austenite-to-martensite-to-austenite loading paths. More specifically, when a stress or load is applied to the shape memory alloy, the shape memory alloy is transformed from austenite to martensite. Upon a subsequent heating to a temperature ∃ A0f, the shape memory alloy returns to austenite. Shape memory alloy also exhibits pseudoelasticity, which is a property that is similar to the shape memory effect and encompasses both superelastic and rubberlike behavior. More particularly, when a stress or load is applied to the shape memory alloy, the shape memory alloy is transformed from austenite to martensite. Upon a subsequent heating to a temperature ∃ A0s, a partial strain recovery of the shape memory alloy occurs. The phase transformations of the shape memory alloy are the basis for the shape memory effect and pseudoelasticity properties that make the shape memory alloy resistant to erosive stresses.
- Additional properties, such as thermal stability and corrosion resistance, of shape memory alloys are presented in the following table wherein a Titanium nickel (TiNi) alloy is presented by way of example:
TABLE 1 Physical Properties of TiNi Property Austenite Martensite Melting Temperature, EC 1300 1300 Density, g/cm3 6.45 6.45 Resistivity, φΩ/cm Approx. 100 Approx. 70 Thermal Conductivity, wEC/ cm 18 8.5 Corrosion Resistance Similar to 300 Similar to 300 series series stainless stainless steel or steel or titanium titanium alloys alloys Yield Strength, Mpa (ksi) 195 to 690 70 to 140 (28 to 100) (10 to 20) Ultimate Tensile Strength, Mpa (ksi) 895 (130) 895 (130) Transformation Temperatures, EC −200 to 110 −200 to 110 Latent Heat of Transformation, 167 (40) 167 (40) KJ atom/kg (cal atom/g) Shape Memory Strain Approx. 1.5 to Approx. 1.5 to Approx. 8.5% Approx. 8.5% - The properties of the shape memory material may be further influenced by cold working the material which refines the grain size and orients the direction of the grains, thereby improving the crystallographic orientation of the grains and the erosion behavior. Cold working may be done when the material is in a billet form, a partially formed shape (e.g., sheet form) or after the final shaping of the material has been accomplished.

FIG. 6 , therein is depicted an austenite-to-martensite-to-austenite shape memory alloy phase transformation inpanels 180 through 186. As illustrated inpanel 180, atool 188, such as the downhole fluid flow control device illustrated inFIGS. 3A, 3B and 4, includes asurface 190 having a shape memory material, such asshape memory alloy 192, integrated therewith. While theshape memory alloy 192 is depicted as a layer onsurface 190 for purposes of explanation, it should be appreciated by those skilled in the art that shapememory alloy 192 may form the entire component and not just the surface oftool 188. Initially, an ambient temperature ∃ A0f is present abouttool 188 as indicated by the expression T ∃ A0f. Accordingly, as previously discussed, at temperature ∃ A0f,shape memory alloy 192 is in austenitic phase as represented byaustenite 194 in the enlarged representation ofshape memory alloy 192. Inpanel 182,tool 188 and, in particular,shape memory alloy 192 is subjected to an erosive stress as represented by arrow 196. As previously discussed, the erosive stress may be a moving fluid, erosive agent such as particulate matter or mechanical stress that causes erosion by friction. Inpanel 184, the erosive stress is continuing as indicated byarrow 198. Further, the sustained erosive stress is sufficient to transform the phase ofshape memory alloy 192 fromaustenite 194 todetwinned martensite 200. In particular implementations, it should be appreciated that the sustained erosive stress generates heat which furthers the phase transformation in accordance with the transition diagram presented inFIG. 5 . Inpanel 186, the erosive stress is concluded and the ambient temperature ∃ A0f persists proximate totool 188. The ambient temperature heatsshape memory alloy 192 to a temperature ∃ A0f, thereby returningshape memory alloy 192 toaustenite 194. Hence,tool 188 havingshape memory alloy 192 absorbed erosive stress without exhibiting erosive wear by executing a reversible phase transformation. - Referring now to
FIG. 7 , therein is depicted an austenite-to-martensite-to-austenite shape memory alloy phase transformation inpanels 200 through 208. As illustrated inpanel 200, atool 210 includes asurface 212 having ashape memory alloy 214 integrated therewith that is subjected to erosion. Initially,shape memory alloy 214 isaustenite 216 andshape memory alloy 214 is being subjected to an erosive stress as represented byarrow 218. Inpanel 202, the erosive stress continues as indicated byarrow 220. The continued stress transformsshape memory alloy 214 fromaustenite 216 todetwinned martensite 222. Inpanel 204, the erosive stress has stopped andshape memory alloy 214 remains inmartensitic phase 222. Further, as illustrated, aheat source 224 appliesheat 226 toshape memory alloy 214 in order to heat the shape memory alloy and effectuate the martensite-to-austenite transformation. The heat source may be a power generator, friction heater, electric line, fuel generator, resistance heater, radioactive source or other downhole or surface heat source. Inpanel 208, the temperature ofshape memory alloy 214 has been increased to a temperature ∃ A0f andmartensite 222 has transformed intoaustenite 216. - Referring now to
FIG. 8 , therein is depicted a martensite-to-austenite-to-martensite-to-austenite-to-martensite shape memory alloy phase transformation inpanels 230 through 240. More particularly, atool 242 includes asurface 244 having ashape memory alloy 246 that is subject to erosive stress. Initially,shape memory alloy 246 isdetwinned martensite 248 in an environment having a temperature # M0f. Inpanel 232, aheat source 250 appliesheat 252 in order to raise the temperature to a temperature ∃ A0f and transformdetwinned martensite 248 toaustenite 254, which is depicted inpanel 234. In one embodiment,heat source 250 may be utilized periodically to remove residual stress that accumulates from excessive stress such as erosion. - In addition to heating, it should be appreciated that in certain situations it may desirable to cool
shape memory alloy 246 as well using a refrigerator with thermal cycles or solid state thermoelectric device, for example. In one implementation, a dissolvable component may be used and it may be desirable to erode the component. For example, if the ambient temperature is higher than the phase transformation temperature of the dissolvable component having a shape memory material in accordance with the present invention, the dissolvable component may be cooled to effectuate a phase transformation and the dissolution of the component - Furthermore, in
panel 234,tool 242 is subjected to an erosive stress, as indicated byarrow 256, which continues inpanel 236, as indicated byarrow 258. The continued erosive stress has transformed theaustenite 254 todetwinned martensite 248. Inpanel 238, the erosive stress has ceased and the temperature oftool 242 is above A0f. Hence, thedetwinned martensite 248 transforms intoaustenite 254. Inpanel 240, the temperature has fallen to less than M0f andaustenite 254 returns todetwinned martensite 248. - While this invention has been described with reference to illustrative embodiments, this description is not intended to be construed in a limiting sense. Various modifications and combinations of the illustrative embodiments as well as other embodiments of the invention, will be apparent to persons skilled in the art upon reference to the description.
