摘要： A rotary latch release mechanism includes axially-aligned upper and lower rotary latch components carried on and rotationally coupled to upper and lower latch assemblies, respectively. The latch release mechanism is movable from an axially-latched position to an axially-unlatched position in response to relative rotation between the upper and lower rotary latch components. The latch release mechanism has a movable land surface that acts in response to relative axial displacement to induce the relative rotation required to release the latch. The latch release mechanism may be configured such that the axial movement of the movable land surface will cause the relative axial movement required to release the latch in combination with the required rotation. Accordingly, the rotary latch mechanism operates in response to externally-controlled axial movement of a movable land surface carried by the latch release mechanism, without requiring externally-induced rotation.

摘要： The present disclosure discloses a drilling machine. The drilling machine may include a base, a mast arranged on the base, an iron roughneck, a drill floor mechanical arm, a top drive arranged on the mast, a pipe racker on a finger board, a power finger board, a power catwalk arranged on the ground, and an elevator arranged on the top drive. The drill machine and a corresponding tripping out and tripping in method may be used to vertically transport a stand between a well center and a region of at least one pipe setback efficiently, which may improve the efficiency of tripping out and tripping in, and reduce the risk of accidents in the well. In addition, the present disclosure provides a corresponding method for offline connecting and disconnecting stands during a drilling operation, which may reduce a preparation time during the drilling, improve the drilling efficiency, and reduce the cost of oilfield development.

摘要： An apparatus for slip monitor and control includes a body; a plurality of slips; a transmitter for each slip; at least one receiver coupled to the body; and an actuator for each slip configured to move the respective slip vertically relative to the body. A method for slip monitor and control includes obtaining slip positional information for a plurality of slips; determining whether the slip positional information for each of the slips matches criteria; and sending one or more control signals to one or more actuators, each actuator configured to move one of the slips vertically relative to a body. A method for handling a tubular includes actuating a plurality of slips to move vertically relative to a body; engaging the tubular with at least one of the slips; measuring positional data of the plurality of slips; and identifying an offset pipe condition.

摘要： hydraulic slip unit for a rotary drive of a rig floor comprises a main body including hydraulically operated slips disposed within a passage that can engage a pipe string within the passage to transmit vertical loads and torque for rotation of the pipe string. A hydraulic swivel is connected to the main body, wherein the swivel includes a first portion attached to the main body to rotate therewith and a second portion slidably mounted to the first portion to rotate relative thereto. Both first and second portions include oil passages therethrough in fluid communication with one another during relative rotation. During rotation of the main body, the second portion is connectable to static hydraulic supply lines that do not rotate, and fluid from the supply lines can travel through the respective oil passages to provide hydraulic power to the slips in the main body to selectively move them.

摘要： A system including an elevator to move a tubular, the elevator including two or more remotely operable latches that can configure the elevator to handle various tubular diameters. A portion of the latches can be laterally offset from each other and another portion can overlap adjacent latches. The elevator can be Atmosphere Explosible (ATEX) certified or International Electrotechnical Commission for Explosive Atmospheres (IECEx) certified according to explosive (EX) Zone 1 requirements with an electronics enclosure contained within a sealed chamber. The elevator can be rotated greater than 90 degrees relative to a pair of links that support the elevator. The elevator can use rotary actuators to operate the latches and rotate the housing of the elevator.

摘要： A downhole tool for a wellbore and method of assembly. Components of the tool include a load member, one or slip members, one or more compression members, and a sealing element between the compression members mounted on a mandrel. The components are designed to prevent pre-set of the tool in the wellbore and facilitate removal of the tool from the wellbore.
