FIG. 1 a portion of astring 10. Thestring 10 is a length of tubing installed in a downhole environment for various purposes such as drilling, injection and/or production. Thestring 10 includes a plurality ofcentralizers 12 which extend outwardly from anouter surface 14 of thestring 10 to prevent damage to thestring 10 when thestring 10 is run into or removed from the downhole environment. The plurality ofcentralizers 12 are disposed along a length of thestring 10 and also around a perimeter of thestring 10. The plurality ofcentralizers 12 may be secured to thestring 10 by any conventional means, including welding and/or one or more mechanical fasteners such as bolts, or may be formed integral to thestring 10. While the embodiment shown inFIG. 1 includes a plurality ofcentralizers 12, it is to be appreciated that in some embodiments,centralizers 12 may be absent from thestring 10. - To monitor and/or control one or more devices downhole, one or more monitoring or
control lines 16 extend along theouter surface 14 of thestring 10. The lines may be, for example, electrical lines, hydraulic lines, and/or fiber optic lines, or the like. Further, while fourlines 16 are shown inFIG. 1 , it is to be appreciated that other quantities oflines 16, for example one, two, or tenlines 16 are contemplated herein. - To protect the
lines 16 along thestring 10, at least oneline passage 18 is disposed along theouter surface 14 of thestring 10 and extending axially along thestring 10. In some embodiments, the at least oneline passage 18 may be disposed circumferentially between twocentralizers 12. The at least oneline passage 18 may have a tubular cross section and in some embodiments may be curved in a circumferential direction to, for example, match a curvature of thestring 10. In some embodiments, the at least oneline passage 18 cross section is a unitary piece. The one ormore lines 16 extend through the at least oneline passage 18 and are protected therein from damage. - In some embodiments, the at least one
line passage 18 extends substantially an entire length of a joint of thestring 10. In other embodiments, however, it may be desired to utilize two or moreinterconnected line passages 18 arranged axially along thestring 10. In one embodiment, eachline passage 18 will extend about 10 feet. Referring toFIG. 2 , afirst line passage 18 may interconnect to asecond line passage 18 via, for example, a pin and sleeve arrangement. Thefirst line passage 18 may include asleeve 20 at one circumferential side and apin 22 at the other circumferential side, while thesecond line passage 18 may similarly include asleeve 20 and apin 22. Thepin 22 of thefirst line passage 18 is engaged in thesleeve 20 ofsecond line passage 18 and thepin 22 of thesecond line passage 18 is inserted into thesleeve 20 of thefirst line passage 18. Alternatively, thefirst line passage 18 may be configured entirely withpins 22 and thesecond line passage 18 may be configured entirely withsleeves 20, or vice versa. While the pin and sleeve arrangement is illustrated inFIG. 2 , it is to be appreciated that other means of interconnecting or joining theline passages 18 may be utilized. For example, theline passages 18 may be interconnected utilizing hinges, a telescoping overlap between the ends of the twoline passages 18, and/or bolts. Further, while a single connection between twoline passages 18 is shown, other quantities ofline passages 18, for example, three or fiveline passages 18 may be arranged along each joint of thestring 10. - To secure the
lines 16 at each end 24 of each joint ofstring 10, anend clamp 26 is utilized. Referring toFIG. 3 , theend clamp 26 extends around the circumference of thestring 10 and secures thelines 16 thereto. Referring toFIG. 4 , theend clamp 26 includes twoclamp hinges 28 configured to rest on theouter surface 14 of thestring 10 when theend clamp 26 is installed. The clamp hinges 28 act as spacers to define a clamp protectedspace 30 between aclamp body 32 disposed between theclamp hinges 28 and theouter surface 14. The clamp protectedspace 30 in some embodiments may be substantially equal to a thickness of thelines 16 to secure thelines 16 therein when theend clamp 26 is secured. Theend clamp 26 includes twoclamp arms 34, oneclamp arm 34 extending from eachclamp hinge 28. Eachclamp arm 34 includes a plurality offingers 36 configured to interlock withfingers 36 of theother clamp arm 34 when theend clamp 26 is closed around thestring 10. With thefingers 36 interlocked, theend clamp 26 is secured in the closed position by, for example, aclamp pin 38 installed through a plurality ofpin holes 40 in the plurality offingers 36 to prevent theend clamp 26 from opening unexpectedly. While the embodiment is shown with two clamp hinges 28, other quantities ofclamp hinges 28 may be utilized. Further, additional spacers may be utilized to define the clamp protectedspace 30. - Referring again to
FIG. 3 , in some embodiments, theclamp body 32 may include atransition passage 42 to protect thelines 16 at thestring 10 portion between anadjacent line passage 18 and theend clamp 26. Thetransition passage 42 may be tubular in cross-section to match theline passage 18 and to protect thelines 16 between theline passage 18 and theend clamp 26. Thetransition passage 42 may further include a slopingportion 44 or other shape to account for any changes in diameter of thestring 10 between theline passage 18 and theend clamp 26. Further, thetransition passage 42 may be joined to theline passage 18 via the pin and sleeve arrangement described above or alternatively via hinges, a telescoping overlap between the end of theline passage 18 and thetransition passage 42, and/or bolts. - In some embodiments, it is desirable to have
lines 16 installed along the length of thestring 10, across couplings of adjacent joints of thestring 10. Referring toFIG. 5 , across-coupling clamp 46 may be disposed at the coupling of two joints ofstring 10. Thecross-coupling clamp 46 axially overlaps each joint ofstring 10 and circumferentially surrounds thestring 10. Thecross-coupling clamp 46 includes acollar 48 disposed at each end and asleeve 50 extending axially between the twocollars 48 across a coupling between the joints of thestring 10. Referring toFIG. 6 , eachcollar 48 includes at least onecoupling hinge 52 and two couplingarms 54 extending from thecoupling hinge 52. Eachcoupling arm 54 may include at least onecoupling spacer 56 that, when thecollar 48 is closed around thestring 10 defines a coupling protectedspace 58 between theouter surface 14 and thecoupling arm 54. The size ofcoupling spacer 56 used determines a height of the coupling protectedspace 58, and differentsized coupling spacers 56 may be utilized depending on a size oflines 16 and/or desired height of the coupling protectedspace 58. In some embodiments, the coupling protectedspace 58 height is greater than a thickness oflines 16 that are disposed in the coupling protectedspace 58. This provides a coupling protectedspace 58 that extends around the circumference of thestring 10 and allows for a helical arrangement of thelines 16 in the coupling protectedspace 58 to, for example, compensate for any variation in circumferential alignment of adjacent string joints 10 at the coupling. Referring again toFIG. 5 , eachcoupling arm 54 includes a plurality ofcoupling fingers 60 configured to interlock withcoupling fingers 60 of theother coupling arm 54 when thecollar 48 is closed around thestring 10. With thecoupling fingers 60 interlocked, thecross-coupling clamp 46 is secured in the closed position by, for example, a coupling pin (not shown) installed through a plurality of coupling finger holes (not shown) in the plurality ofcoupling fingers 60 to prevent thecross-coupling clamp 46 from opening unexpectedly. - Referring again to
FIG. 1 , in some embodiments, thestring 10 includes ascreen 62 at theouter surface 14 to filter flow entering thestring 10 for undesired materials. In some embodiments, theouter surface 14 may be a flow throughtubular 64 having aline 16 attached thereto. Theline 16 attached to the flow throughtubular 64 may be a control line or monitoring line that is, for example, an electric line, hydraulic line, fiber optic line or the like. - While one or more embodiments have been shown and described, modifications and substitutions may be made thereto without departing from the spirit and scope of the invention. Accordingly, it is to be understood that the present invention has been described by way of illustrations and not limitation.
