ATTORNEY United States Patent 3,254,776 PIPE HANDLING AND STURAGE APPARATUS Morris A. Brown, Dallas, Tern, asslgnor to Snceny Mobil Oil Company, Inc, a corporation of New York Filed Apr. 10, 1964-, Ser. No. 353,716 11 Claims. (1. 214-25) This invention relates to apparatus used for handling and storing pipe in connection with the operation of a rig used in drilling wells. More specifically, this invention relates to a semiautomatic form of pipe racking apparatus.
In the drilling of wells into the earth, strings of pipe are utilized to support the drill bit and other tools which must be used in drillin and various procedures carried out in connection with wells. The pipe strings generally are made up of a number of pipe joints which must. be assembled and secured together as the drill string is lowered into a well. In order to remove the drill string from the well, it is necessary that the various joints of pipe be disconnected as the drill string is lifted from the well. It facilitates both assembly anddisassembly of the drill string to have means at hand which will permit the joints of pipe to be quickly and etficiently brought to the proper location for assembly and removed and stored after disassembly.
With the present trend in apparatus for drilling wells leaning toward the portable-type rig which is readily transportable between sites and quickly set up and taken down at the sites, it becomes more desirable to have equally portable and transportable apparatus for the handling of the pipe necessary in drilling.
It is one object of the present invention to provide pipe handling and racking apparatus for use with a well drilling rig. It is another object of the present invention to provide semiautomatic pipe handling and racking apparatus which may be compact in size and quickly and easily assembled and disassembled at a rig site. These and other objects of the invention will be evident from the following description taken in conjunction with the accompanying drawings.
In the drawings:
FIGURE 1 is an end view in elevation of one embodiment of apparatus constructed in accordance with the invention. FIGURE 1 illustrates the step in the operation of the apparatus of the invention in which a joint of pipe is received from the tilted pipe rack by the pipe trough.
FIGURE 2 is a view similar to FIGURE 1 showing the joint of pipe in the trough ready to be conveyed to the drilling rig.
FIGURE 3 is another view similar to FIGURE 1 illustrating the discharging of a joint of pipe from the trough to the rack.
FIGURE 4 is a top view in elevation of the invention showing both the rack and the trough.
FIGURE 5 is a side view in elevation showing the pipe trough and a portion of a drilling rig with which the invention is employed.
FIGURE 6 is a view in perspective of an alternative form of feed mechanism which may be utilized with the pipe trough of the invention.
FIGURE 7 is a top view in elevation of the pipe trough illustrated in FIGURE 6.
FIGURE 8 is a view in perspective of a further modification of the pipe trough illustrated in FIGURES 6 and 7.
Referring to the drawings, particularly FIGURE 4, the invention generally comprises a pipe rack 10 adapted to receive and store one or more layers of pipe and a pipe trough 11 which functions to convey pipe between a drilling rig and the pipe rack. The pipe trough discharges pipe joints to the pipe rack and receives pipe joints from the pipe rack. Both the pipe rack and the pipe trough may be independently raised and lowered. The pipe rack also may be tilted from a horizontal position by raising and/or lowering either side independently to facilitate manipulation of the pipe on the rack. The pipe trough, as is particularly evident in FIGURES 1, 2, and 3, is rotatable about its longitudinal axis in order to permit it to discharge pipe to the rack and receive pipe from the rack.
As shown in FIGURE 4, pipe rack 10 is formed of side members 12 and 13 and end members 14 and 15. These members are generally assembled in a rectangular configuration, though the exact shape of the pipe rack is not material so long at it is adequate to provide a base on which one or more layers of pipe may be stored in an orderly fashion. The side and end members forming the pipe rack are connected together in any satisfactory manner which will permit ready assembly and disassembly of the rack. In order to store the pipe in a manner which will not impose undue bending stresses on it, it may be necessary to provide more than the two end members such as 14 and 15 or to provide some form of decking over the surface of the pipe rack, depending upon the length, wall thickness, and material of the pipe.
Referring to FIGURES 1-3, pipe rack 10 is supported on a plurality of jacks 20 which may be either mechanical or hydraulic. In the particular embodiment of the apparatus disclosed, one jack is located near each of the four corners of the pipe rack. Jacks 20 are supported on mats or plates 21, 22, 23, and 24 (FIGURE 4). The mats provide a substantial bearing surface for supporting the pipe rack and trough so that the apparatus may be placed on bare ground near a drilling rig. The mats may be made of material such as sheet steel. As is evident from FIGURES 1-3, jacks 29 are utilized to adjust both the elevation of rack 10 and the tilt angle of the rack. If the particular demands to be placed on the apparatus do not require that the elevation of rack 10 be adjustable, then the jacks 2i) nearest side 12 may be replaced with fixed length supports, leaving the tilting of the rack to be effected by manipulation of the jacks 20 nearest side 13.
After the pipe trough has received one joint of pipe, as shown in FIGURE 1, it is rotated into the position illustrated in FIGURE 2; and the design of the elements discussed immediately above should be such that, as the trough is moved into the position shown in FIGURE 2, the edge of the trough adjacent side 13 of the pipe rack will move up to prevent the next joint of pipe rolling into the trough. Of course, the jacks 30 and 31 also must be designed such that the elevation of the ends of the pipe trough may be independently varied to give the pipe trough a tilt from end to end as illustrated in FIGURE 5 to facilitate moving each joint of pipe into the vicinity of the portion of a drilling rig where the drill strings are made up and broken down during drilling.
One necessary function of the pipe trough is movement of each joint of pipe handled by it along its length to and from the vicinity of the drilling rig as shown in FIG- URE 5. The form of pipe trough illustrated in FIG- URES 4 and 5 is provided with powered rollers 32 which are driven by motors 33 interconnected with the rollers by some form of gearing. Each roller and its respective motor is mounted on the bottom of the trough with the roller being positioned in a slot opening through the trough. A joint of pipe lying in the trough contacts the rollers exposed through the bottom of the trough so that rotation of the rollers will cause the pipe joint to be propelled along the length of the trough. The rollers are operable in either direction so that the pipe joint may be moved along the trough toward the drilling rig or moved along away from the drilling rig into position for discharging the pipe joints to the pipe rack.
A modified form of pipe trough 11 is illustrated in FIGURES 6 and 7. Secured to the bottom of the trough is a hydraulic cylinder 40 which actuates rod 41 connected to a dog 42 extending through the bottom of a slot 43 (FIGURE 7) formed through the bottom of the trough. Free-turning rollers 44 and 45 are secured through slots in the bottom of the trough to facilitate the sliding of a joint of pipe along the length of the trough. Dog 42, extending through the bottom of the trough, contacts an end of a joint of pipe and, when actuated by the hydraulic cylinder, moves the joint of pipe along the trough. In lieu of hydraulic cylinder 40, motor means may be used to actuate rod 41 through any one of several forms of gear connections such, for example, as a rack and pinion gear arrangement.
Illustrated in FIGURE 8 is an alternative embodiment of the pipe trough illustrated in FIGURES 6 and 7. This particular form of pipe trough is especially adapted for use under conditions where a drilling rig floor is at an elevation in excess of that attainable by the pipe trough simply through the action of raising it by units 25. The pipe trough illustrated in FIGURE 8 is identical to that of FIGURES 6 and 7 with the exception that the trough portion itself is somewhat longer and is articulated in the sense that the portion is connected at the end nearest the drilling rig in such a manner that the elevation of its outward end may be varied depending upon the height necessary to get the pipe joint ends intothe required location for connection into the swivel. Portion 50 of the trough may be a separate section, if desired, which is secured in the proper position to slide the pipe joints to and from the major portion of the trough when the apparatus is set up at a drilling rig site. Portion 50 may be referred to as an auxiliary trough slide.
FIGURE 5 illustrates the relationship of the apparatus of the invention to a drilling rig with which it is employed. Only that portion of the drilling rig which is necessary to the function of the apparatus of the invention is illustrated for the purposes of understanding the operation of the invention. Derrick 60 may be any form of derrick normally employed in the drilling of wells. More probably, derrick 60 will be of the smaller, portable type. Suspended from the upper end of the derrick are cables 61 which movably support a traveling block 62. Secured to and supported by the traveling block is a power swivel 63 which is a form of hydraulic motor used with some of the present-day, portable-type drilling rigs. The swivel is mounted on horizontal pivots and balanced so that it may be easily pivoted by hand to manipulate it into position for engagement with the end of a pipe joint. Positioned in the rig floor are power slips 64 which assist in breaking and making up joints in the drill string. I
The apparatus of the invention is employed during the carrying out of two major functions of a drilling rig,
namely, that of introducing a drill string into a well and the removal of a drill string from a well. In carrying out these functions, pipe joints are removed from storage, made up into a drill string, and the drill string is lowered into the well as it is made up. In removing a drill string from a well, the pipe joints are disassembled and stored. In describing the procedure of making up a drill string and lowering it into a well, reference will be made to FIGURES 1, 2, and 5. Referring to FIGURE 1, two partial layers of stacked pipe are illustrated separated by dividers 65 which are laid on each layer of pipe in order to provide a base or support for the next succeeding layer of pipe. The layers of pipe will have been stored on the pipe rack either as the equipment is installed for the starting of the drilling of a well, or, where the well has been partly drilled, the pipe will have been stored on the rack each time that the drill string is removed from the well and broken down. To start the make-up of a drill string, pipe trough 11 is adjusted by means of units 25 and pipe rack 10 is adjusted by jacks 20 until the trough is at the height of the uppermost layer of pipe on the pipe rack so that the trough will be in a position to receive the pipe joint by joint from the rack. As shown in FIGURE 1, the pipe trough is rotated through an angle of approximately ninety degrees to a position where a joint of pipe may be rolled into the trough from the uppermost layer of pipe on the pipe rack. The pipe rack is tilted by jacks 20 toward the edge adjacent to the pipe trough. A joint of pipe will then roll into the pipe trough as shown in FIGURE 1. The pipe trough is rotated back by means of its supporting cylinders to a substantially horizontal position as illustrated in FIGURE 2. As previously explained, the axis about which the trough is rotated and the position of .the edge of the trough are such that the edge nearest the pipe rack will, upon return of the trough to a horizontal position, fit in between pipe joints such that the trough picks out one joint from the uppermost layer of pipe on the pipe rack. With one joint of pipe in the pipe trough, the end of the pipe trough nearest the drilling rig, as shown in FIGURE 5, is raised by means of unit 25 until the elevation of that end of the trough is such that the pipe joint within the trough may be conveyed to a point where it may be connected to power swivel 63. With this end of the pipe trough in the proper elevation, motors 33 are actuated to rotate the rollers 32 for propelling the pipe joint along the pipe trough toward the drilling rig. Of course, if the embodiment of the pipe trough illustrated in FIGURES 6 and 7 is being utilized, the pipe joint will be conveyed along the pipe trough by the dog 42 actuated by cylinder 40. Also, if the elevation of the drilling rig flooris such that additional height is necessary, the embodiment illustrated in FIGURE 8 may be used so that auxiliary trough slide 50 will guide the pipe up to the vicinity of the power swivel. With the pipe joint moved along the trough to the point where it may be connected to the power swivel, the joint is engaged by the tongs 'which are used to hold the pipe and prevent its being rotated while the power swivel is actuated to engage the threads of the pipe joint. With the power swivel connected to the end of the pipe joint, the pipe joint is lifted by raising the power swivel with the block 62 until the lower end of the pipe joint may be engaged with that portion of the drill string which is already in the well and is being held by power slips 64. The power slips are then disengaged and the power swivel is lowered until the pipe joint which has just been connected is down to the point where the power slips are again engaged to hold the drill string until the next joint of pipe can be secured in place. The pipe trough is then lowered until it is in position alongside the pipe rack to receive another joint of pipe. This procedure is repeated with each joint of pipe being removed from the pipe rack and engaged with the drill string until the desired number of joints of pipe have been placed within the string.
When it is necessary to remove the drill string from the well and stack the pipe, the power swivel is raised by means of the block until a joint of pipe is supported by the swivel above the power slips, at which time the power slips are engaged with the joint of pipe immediately below the joint to be removed. The tongs are then used to break the connection between the joint being held by the power slips and the joint of pipe which is to be removed and stacked. With the connection broken by the tongs, the completion of the backing out of the joint is done by the power swivel. The lower end of the disconnected joint is then maneuvered to the end of the pipe trough nearest the drilling rig, such pipe trough end having been raised by means of a unit 25 until the pipe trough is in position to receive the joint of pipe. The joint of pipe is allowed to slide into the trough with its movement along the trough being assisted by power rollers 32. When the joint of pipe is fully within the pipe trough and alongside the pipe rack, the trough is rotated approximately ninety degrees until it is in the position shown in FIGURE 3, at which point the joint of pipe is discharged or dumped from the trough onto the pipe rack. The pipe rack may be inclined to substantially match the inclination of the troughs. Also, the pipe rack is tilted so that each joint of pipe will roll along the rack away from the trough. It is not necessary that there be an ejection mechanism for discharging the pipe joint, as the position of the trough will cause the joint to roll from the trough onto the rack. Since the pipe rack is tilted away from the trough, the joint of pipe will roll down the pipe rack until it engages the stop at the farthest edge of the pipe rack or bumps into the last joint of pipe which was removed. The joints of pipe are successively removed by this procedure until all of the desired joints have been taken from the well and stored on the pipe rack. If sufficient joints are removed to make upseveral layers of pipe on the rack, as each layer is filled, dividers 65 are laid on the layer to provide a base for receiving the next succeeding layer of pipe joints.
