摘要： A tubular running tool equipped with a mandrel having an elongated body with a longitudinal axis. The mandrel is configured with a plurality of offset stepped ramps. A plurality of slips are disposed on the mandrel with stepped ramps configured for complementary engagement with the mandrel offset ramps. The mandrel is configured for actuation to urge the slips radially outward for engagement of a gripping portion on the slips with an inner surface of a tubular. A method using the tool for running a tubular and providing a makeup torque.

摘要： Systems and methods for installing a coiled tubing pumping system in a well permit the use of a standard wellhead. A method for installing the coiled tubing pumping system includes the steps of connecting a continuous length of coiled tubing to the coiled tubing pumping system, lowering the coiled tubing pumping system and coiled tubing into the production tubing, and temporarily supporting the weight of the coiled tubing pumping system with an installation kit. The method continues with the steps of cutting the continuous length of coiled tubing to form a coiled tubing segment attached to the coiled tubing pumping system, attaching a deployment assembly to an upper end of the coiled tubing segment connected to the coiled tubing pumping system, and lowering the deployment assembly, the coiled tubing segment and the coiled tubing pumping system into the well until the deployment assembly lands on the seating element.

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.
