摘要： A compact rotary surface jack with a driven rotary hanger flange on an upper travelling plate of the jack is provided by the invention; the jack is preferably a horseshoe jack. Capabilities to work on the well such as rotating and reciprocating while cementing casing in place in the well, or setting or unsetting in-hole devices such as packers, anchors and bridge plugs (etc.) by providing low speed (1-6 rpm) rotational force and short (1-6 feet) linear vertical forces to tubulars in a well to which the device is attached, are enabled.

摘要： An apparatus is configured for undersea use, such as for penetrating a seabed for forming a borehole therein, including with optional data acquisition and logging capabilities. A first or base module (12) of the apparatus is adapted for engaging the seabed. A first elevator (16) provides longitudinal movement of a second or upper module (14) relative to the base module (12) along a drilling axis. The relative movement of the upper and base modules may be used in the course of independently moving first (18) and second (20) rotary units along the drilling axis to cause a drill rod (R) and a drill casing (C) to penetrate the seabed such that the collapse of the borehole is avoided.

摘要： An offshore drilling vessel includes a floating hull subjected to heave motion. The hull includes a moonpool and a drilling tower near the moonpool. A drilling tubulars storage rack is provided for storage of drilling tubulars. The vessel includes a heave motion compensation support that is adapted to support a slip device whilst performing heave compensation motion relative to the heaving motion of the vessel. A racking device is provided with a heave motion synchronization system that is adapted to bring a tubular retrieved from the storage rack in heave motion into a vertical motion that is synchronous with the heave compensation motion of the string slip device. The racking device includes vertical rails and at least two separate motion arm assemblies mounted on said vertical rails. Each separate motion arm assembly includes its own vertical drive which is electrically connected to the heave motion synchronization system.

摘要： An elevator system that supports a tubular member includes an elevator movable between a first elevator position and a second elevator position. A mechanical signal mechanism is coupled to the elevator. A valve is coupled to the mechanical signal mechanism. The mechanical signal mechanism is configured to transmit a mechanical signal by a mechanical control cable to move the valve into a valve position to send a valve signal that the elevator is in the second elevator position.

摘要： An actuator assembly with integrated torque turn monitoring is described. Embodiments include a rotationally fixed outer hydraulic section and a rotationally independent inner hydraulic section which incorporates torque load sensors, axial load sensors, and rotational speed sensors directly into the inner hydraulic section. The inner hydraulic section is coupled to an outer cage by a cage ring and is axially movable relative to the inner mandrel. Upper and lower fluid chambers are disposed between the outer housing assembly and the inner mandrel. Fluid pumped through a lower pressure port into the lower chamber moves the housing assembly in a first direction, and fluid pumped through an upper pressure port into the upper fluid chamber moves the housing assembly in a second direction.

摘要： An apparatus for gripping a tubular includes a body. A slip carrier is coupled to an inner surface of the body. The slip carrier is configured to pivot between an open position and a closed position. A tubular is configured to be introduced laterally into the body when the slip carrier is in the open position. A slip is coupled to the slip carrier. The slip is configured to move radially between a first position that is spaced apart from the tubular and a second position that contacts and grips the tubular.
