Background
The present disclosure relates generally to methods and apparatus for handling tubulars (e.g., drill pipe stands) on a drilling rig.
Drilling involves tripping of the drill string, during which the drill string is pulled out of the well or lowered into the well without drilling. Tripping may typically occur to change all or a portion of the bottom hole assembly, such as the drill bit. During tripping, a plurality of drill pipe stands are disconnected from the rest of the drill string and stored in, or supplied from, a setback of the drilling rig and connected to the rest of the drill string. The drill string can be moved rapidly between two successive disconnections or connections of the drill rod holder. Thus, storing or supplying the stand to or from the setback can be an operation that limits the tripping speed of the drill string.
Traditionally, tripping is performed by human operators, such as crane operators and drilling workers. In a typical tripping operation, the drill string is pulled out of the well using an elevator connected to a traveling block, and the drill string is placed in slips. Then, the weight of the 'bracket to be disconnected' is carried by the moving block, and the bracket connection is disconnected by using the clamp. The drilling worker manually positions the lower end of the hanger bracket on the setback box and the weight of the bracket is reduced on the setback box. Finally, the upper end of the stand is disengaged from the hoist and the crane operator positions the upper end of the stand in the fingerboard.
To speed up the tripping, a drilling rig having an unconventional setback and racking module may be designed, such as shown in PCT application publication WO 2017/190120. The upper and lower arms and the telescoping top drive can be used to utilize such unconventional setback and racking modules and to accelerate tripping. A lift arm (such as shown in U.S. application publication No. 2016/0160586) or a combination rotary table and pipe mover (such as shown in U.S. patent No. 8,550,761) may be used to accelerate the storage of the racks into the setback.
Despite recent advances, there remains a need in the art for apparatus and methods for accelerating drill string tripping, which preferably can be retrofitted on conventional land drilling rigs.
Disclosure of Invention
The present disclosure describes a lift system that may be part of a tubular handling system for a drilling rig.
The lift system may include two doors. Each of the two doors may be connected to a mast of the drilling rig for rotation relative to the mast. For example, a derrick of a drilling rig may include two spaced apart trusses. Each of the two doors may be connected to a respective one of the two trusses. Each of the two doors is rotatable between a first position in which the door is located in the space between the two trusses and a second position rotated approximately a quarter turn from the first position.
The lifting system may comprise two track sections. Each of the two track portions may be connected to a respective one of the two doors for rotation relative to the respective one of the two doors. For example, each of the two track portions may be rotatable about half a turn from a first position on one side of a respective one of the two doors to a second position on the opposite side of the door.
The lift system may include a vertical rail connectable to a mast of a drilling rig. Either of the two track portions may optionally form part of the vertical guide rail and/or may be integrated and fixed to the vertical guide rail. For example, each of the two track portions may comprise at least one stud. The upper track portion of the vertical guide track may include at least one vertical aperture sized to receive at least one stand pin. Each of the two track portions may comprise at least one second vertical hole. The lower track portion of the vertical guide track may include at least one second vertical pin sized to be received in the at least one second vertical hole. The lower track portion may be connected to a mast of a drilling rig for selective vertical movement relative to the mast. For example, the actuator may be connected to the lower rail portion of the vertical guide rail. The actuator may be configured to move the lower track section vertically relative to the mast. The horizontal pin may secure the lower track section to a vertically upper position of the mast. Furthermore, each of the two track sections is vertically movable relative to the mast.

The lift system may include a controller. The controller may be programmed to automatically disconnect a first of the two track portions from the upper track portion of the vertical guide in a first order, rotate a first of the two doors connected to the first track portion relative to the mast to an outer position beside the mast, rotate the first track portion relative to the first door from one side of the first door to an opposite side of the first door, and rotate the first door relative to the mast to an inner position below the mast. The controller may be further programmed to automatically rotate a second one of the two doors to an outer position beside the mast with respect to the mast, rotate a second one of the two track sections with respect to the second door from one side of the second door to an opposite side of the second door, rotate the second door to an inner position below the mast with respect to the mast, and connect the second track section with the upper track section of the vertical guide in a second sequence interspersed in the first sequence.
The lift system may include a pipe handling trolley that may be connected to a vertical rail above the hook trolley. The auxiliary drill line may be connected to the pipe handling trolley. For example, the auxiliary drill line may be connected directly to the pipe handling trolley. The auxiliary drill line may be connected to a second reel, which may be different from the first reel. The lifting dogs may be attached to a pipe handling trolley. The lifting dogs may include a cylinder and a pair of prongs configured to open and close in unison upon actuation by the cylinder.
The controller may alternatively or additionally be programmed to sequentially automatically raise the drawbar trolley with the tubular gripped in the elevator, the lifting jaws gripping the tubular, lower the drawbar trolley when the elevator is opened, and raise the pipe handling trolley with the tubular gripped in the lifting jaws. Alternatively or additionally, the controller may be programmed to sequentially automatically raise the pipe handling trolley with a pipe stuck in the lifting dogs, raise the hooking trolley while the elevator is stuck, open the lifting dogs, and lower the hooking trolley with a pipe stuck in the elevator.

14A-14I illustrate the location of a tripping sequence, one skilled in the art will readily appreciate, given the benefit of this disclosure, that a tubular handling system may be used to perform a tripping operation, and that the location of the tripping sequence is similar to the chronologically reverse tripping sequence. Further, while figures 14A-14I show the tubular handling system with the auxiliary line, pipe handling trolley and lifting dogs omitted, these elements may be used to hold and/or lift the upper end of the

The kick-off controller 206 may be programmed to set the state for one finite state machine based on another finite state machine changing state so that the operation of the hoist
The hoist controller 202 may be programmed as a finite state machine that implements the operation of the automated hoist
Turning to fig. 15B, the pickoff controller 206 may then transition the finite state machine that causes automatic control of the operation of the hoist
Turning to fig. 15C, pickoff controller 206 may then transition a finite state machine that automates the operation of hoist
The robot controller 205 may be programmed as a finite state machine that implements the operation of the automated

Turning to FIG. 18B, the output of state 240 is a twisted connection. State 240 receives input 242 from a feedback device for detecting the torque applied by the torque wrench. Upon detection of the torque set point, the finite state machine transitions to state 244. The output of state 244 opens the jaws of a static and/or torque wrench of
