A sucker rod tong assembly for fastening together sucker rods to a rod coupling, where the assembly can include a two-stage mechanical drive mechanism. The first stage can connect an upper sucker rod to a lower sucker rod via a rod coupling. The first stage can be limited in mechanical ability to tighten the connection to a pre-set shoulder torque value. The second stage can then be hydraulically and mechanically sequenced, using a linear gear drive mechanism, to rotate a main tong pinion gear that can further rotate the sucker rod connection through a fixed circumferential displacement to a mechanical stop.

A back-up wrench device of a top drive assembly of a drilling rig comprises a gripper device operable to grip an end of a drill pipe, and at least one fluid actuator operable to compensate for thread travel during makeup or breakout operations. The back-up wrench device can comprise a first housing coupled to the gripper device and a second housing coupled to a support structure of the top drive assembly, and can comprise a primary hydraulic housing movably coupled to the first and second housings. The at least one fluid actuator can include upper and lower fluid actuators each movable through upper and lower fluid chambers of the primary hydraulic housing during respective makeup and breakout operations to compensate for thread travel. Associated systems and methods for thread compensation with the back-up wrench are provided.

A method for accelerated break out of connected multi-segment tubulars by setting hydraulic fluid pressure to between 100 and 3000 psi, connecting the stationary wrench to a first segment of a multi-segment tubular, connecting a pivoting wrench to a second segment of the multi-segment tubular, and activating a pivoting hydraulic cylinder with a lever to break out the first segment from the second segment and wherein the pivoting wrench is configured to operate right side up and upside down for optimizing pivoting wrench flat fit.

A wrench assembly comprises upper and lower clamp assemblies each having a plurality of grip assemblies, a plurality of torqueing cylinders, and a hydraulic circuit. The hydraulic circuit is in fluid communication with the grip assemblies and the torqueing cylinders and is configured to control a gripping force applied by the grip assemblies relative to a torqueing force applied by the torqueing cylinders. The hydraulic circuit is configured to maintain the gripping force in a proportional relationship with the torqueing force.

A swivel connection tool holds a tubular of a work string or a drill string while a swivel connects or disconnects from the tubular. The swivel connection tool has a base mounted to a work floor of a derrick of a workover rig. The swivel connection tool is fixed spaced-apart from a hole in the work floor positioned over the wellhead. The swivel connection tool has a yoke oriented at an incline with respect to horizontal.

A torque device for guiding a first torque device member relative to a second torque device member includes the first and second torque device members. Each of the torque device members has an operational axis of rotation and three clamp bodies spaced about the operational axis. The clamp bodies are movable between a retracted passive position and an extended active position. The torque device also includes a guide ring on one of the torque device members. The guide ring includes one or more guide ring sections. In addition, the torque device includes at least two guide elements on the other of the torque device members. Each guide element being movable with one of the clamp bodies of the respective torque device member. When the clamp bodies of the respective torque device member are in their retracted positions, the guide elements abut or are close to the guide ring, and when the clamp bodies of the respective torque device member are in their extended positions, the guide elements are moved away from the guide ring.

A pipe racking system and method, of which the pipe racking system includes a vertical column extending upwards from a rig floor, a main arm that is movable vertically along the column, a gripper connected to a distal end of the main arm and movable therewith, and an elevator including a plurality of slips configured to engage an outer diameter surface of a tubular and support a weight of the tubular by gripping the outer surface of the tubular. The elevator is suspended from the gripper or a distal end of the main arm via one or more suspension arms. The system also includes one or more guide arms connected to the vertical column. The one or more guide arms are configured to maintain a vertical orientation of the tubular.

A tong includes a frame having jaws configured to engage a tubular and a tong control assembly disposed on the frame. The tong control assembly includes a housing connected to the frame, a shutoff switch, and a toggle lever located at a suitable position on the housing, whereby the toggle lever is configured to be operated while the shutoff switch is depressed, and wherein the toggle lever is configured to control at least one of: a rotational speed of the jaws and a rotational direction of the jaws. A method of operating a tong includes clamping a first tubular using first jaws of a tong, clamping a second tubular using second jaws of the tong, rotating the first tubular relative to the second tubular, and controlling a rotational speed of the first tubular using a toggle lever disposed on a frame of the tong.

A method of making a connection between a first tubular and a second tubular includes gripping the first tubular using a power tong; gripping the second tubular using a backup tong; applying a torque to the first tubular using a power tong; and moving the power tong at a predetermined speed to compensate for a weight of the power tong.

An automatic auxiliary workover rig includes a silo body arranged on a skid-mounted baseplate, a guide-roller type elevator, a random-folding type traveling block rigid guide device, a truck-mounted folding type manipulator, a slip, a flatcar up-down adjustment device, a detecting and conveying device, and a transfer device. The automatic auxiliary workover rig cooperates with an existing workover rig to complete ascending and descending of a sucker rod of an oil pipe during minor overhaul. The slip is located above a wellhead blowout preventer, and is configured to clamp and loosen the oil pipe of a wellhead. The silo body is configured to store and output the oil pipe. The truck-mounted folding type oil pipe manipulator garbs the oil pipe and then ascend and descend the oil pipe, meanwhile the manipulator is equipped with a height adjusting device to realize flexible joint in tube thread fastening and unfastening.
