  • a casing string may be disposed downhole into the wellbore and cemented in place to stabilize, reinforce, or isolate (among other functions) portions of the wellbore.
  • strings of drill pipe and casing are often connected together, end-to-end by threaded connections, where a female "pin" member of a first tubular is configured to threadably engage a corresponding male “box” member of a second tubular.
  • the process by which the threaded connections are screwed together is called “making-up” a threaded joint and the process by which the connections are disassembled is referred to “breaking-out” the threaded joint.

  • drilling rig 101 used to run tubular members 111 (e.g., casing, drill pipe, etc.) downhole into a wellbore.
  • drilling rig 101 includes a frame structure known as a "derrick" 102 from which a traveling block 103 and an elevator 105 and/or a top drive (not shown) may be used to manipulate (e.g., raise, lower, rotate, hold, etc.) tubular members 111.
  • traveling block 103 is a device that is located at or near the top of derrick 102, in which traveling block 103 may move up-and-down (i.e., vertically) to raise or lower tubular members 111.
  • traveling block may be a simple "pulley- style" block and may have a hook 104 from which objects below (e.g., elevator 105) may be hung.

In the closed position, the movable components form a load bearing ring (or shoulder) about or upon which tubular members 111 may bear and be lifted. In the open position, the movable components of elevator 105 may move away from one another to allow the tubular members 111 to be brought within or removed from elevator 105.

  • An elevator for example 105 in Figure 1, or other lifting device (e.g., cable and/or winch) may then grasp an end of a tubular member 111 located within access opening 121 and may then raise the tubular member 111 up in derrick 102 so that it may be threadably connected to the remainder of a downhole string 115 of tubular members 111.
  • the reverse process or one substantially similar thereto, may be used, such as when removing tubular members from the drilling rig 101.
  • tubular members 111 may vary in size and length as described above, if a selected tubular member 111 is too short (or long) for pipe ramp 125 (and rigidly mounted end stop 131) and therefore unable to reach access opening 121, drilling rig hands (i.e., crew members) may be required to place spacer blocks under a distal end of the tubular member 111 until elevator 105 is able to reach a proximal end of the tubular member 111 at access opening 121. Additionally, tubular members 111 may be cumbersome and/or difficult to handle because of their size, weight, and length such as when manually manipulating tubular members 111.

  • First, embodiments disclosed herein may provide for an end stop that prevents or minimizes damage to tubular members being grasped for assembly from a pipe rack. For example, when a tubular member engages the movable assembly of the present disclosure, the movable assembly will allow the tubular member to pass therethrough without having to pick up and move or drag the pipe over the end stop. Further, embodiments disclosed herein may provide for an end stop that is movable to facilitate the assembly of tubular members.
  • the movable member of the end stop may be able to move a tubular member resting thereupon, thereby allowing a user to control the location of the tubular member for grasping and assembly.

Abstract

L'invention concerne une butée de fin de course ajustable qui peut sélectivement inclure un ou plusieurs éléments suivant : au moins un organe de guidage, un organe pliable, un ensemble amovible, un mécanisme d'entraînement et un mécanisme d'ajustement de position. L'organe de guidage peut être tel que l'organe pliable et/ou l'ensemble amovible sont fixés à celui-ci. L'organe pliable peut être configuré pour se plier lorsque l'extrémité de l'organe tubulaire coopère avec l'organe pliable dans une première direction et résiste au pliage lorsque l'extrémité de l'organe tubulaire coopère avec l'organe pliable dans une seconde direction. L'ensemble amovible peut être fixé de façon mobile à l'organe ou aux organes de guidage, l'ensemble amovible étant configuré pour se déplacer le long d'au moins une partie de la longueur du ou des rails de guidage. En outre, le mécanisme d'entraînement peut être utilisé pour positionner sélectivement l'organe pliable et/ou l'ensemble amovible le long du ou des organes de guidage.
