摘要： A running tool includes subassemblies which release the running tool from the liner hanger in response to application of alternating tensile and compressive forces after application of left-hand torque. A running tool includes subassemblies which set the liner hanger in response to left-hand torque followed by increased pressure, and in response to increased pressure without prior left-hand torque being applied. A running tool includes threaded connections, without torque transmitted through the running tool being transmitted by the threaded connections. A method of setting a liner hanger includes applying a compressive force to the running tool; then applying left-hand torque to the running tool; and then applying a tensile force to the running tool. A method of releasing a liner hanger includes applying left-hand torque to the running tool; and then releasing the running tool from the liner hanger by applying a tensile force to the running tool.

摘要： A high pressure well cementing plug assembly for use in a pipe during the cementing of the pipe in a well bore is provided by the present invention. The assembly basically comprises top and bottom cementing plugs which include high strength inner tubes for supporting high differential pressures exerted on the plugs. The bottom end of the inner tube of the bottom plug is adapted to supportingly engage a float shoe or the like upon landing. Also, the bottom end of the inner tube of the top plug and the top end of the inner tube of the bottom plug are adapted to supportingly engage each other when the top plug lands on the bottom plug. The high strength inner tubes support high pressure differentials exerted on the plugs and prevent the plugs from collapsing or otherwise being damaged.

摘要： A side intake valve assembly for use in a subterranean well in conjunction with a second or lower valve assembly, and a hollow connecting body for connecting the side intake valve assembly and the second or lower valve assembly. The side intake valve assembly allows water separated from the production fluid to be forced downwardly through the intake valve assembly and the second or lower valve assembly into a water disposal zone. A one-way valve in the side intake valve assembly is a gravity operated ball valve.

摘要： A hydraulic jar for delivering impacts downhole. The jarring mechanism includes a cup-type piston that moves through a seal bore. The cup is deformable in response to fluid pressure so that it expands each time it moves through the seal bore to compensate for wear on the lip. Since only minimum interference is required between the piston and seal bore, less material may be used. This reduces the force required to reset the tool, which is particularly advantageous in horizontal wells. The seal bore may be slightly wider at the exit; the cup expands to this exit diameter, ensuring an interference fit as the cup travels back through the smaller diameter entry section. The entry end of the seal bore may include longitudinal grooves. This prevents the piston cup from rupturing by preventing a fluid seal around the lip until the most of cup is inside the seal bore.
摘要翻译： 用于在井下输送冲击的液压罐。 振动机构包括移动穿过密封孔的杯形活塞。 杯子响应于流体压力而变形，使得其每次穿过密封孔时都会膨胀，以补偿唇缘上的磨损。 由于在活塞和密封孔之间只需要最小的干扰，所以可以使用更少的材料。 这减少了重置工具所需的力，这在水平井中是特别有利的。 密封孔可以在出口处稍宽一些; 杯子膨胀到该出口直径，确保当杯子通过较小直径入口部分返回时过盈配合。 密封孔的进入端可以包括纵向凹槽。 这防止活塞杯通过防止围绕唇缘的流体密封而破裂，直到杯的大部分位于密封孔内。

摘要： A setting tool for an expandable liner hanger. A method includes the steps of: releasably securing the setting tool to the hanger, the setting tool including an expansion cone for displacing through the hanger; and conveying the setting tool and hanger into the well on a generally tubular work string while no portion of the hanger extends longitudinally between the expansion cone and the work string. A setting tool includes an expansion cone, which is displaceable through the liner hanger to expand the hanger; at least one piston positioned on one side of the expansion cone; and an anchoring device for releasably securing the setting tool to the liner hanger, the anchoring device being positioned on an opposite side of the expansion cone. The expansion cone is pressure balanced between its two sides when the expansion cone is displaced through the liner hanger.

摘要： Electrohydraulic actuators and associated methods are utilized to control the operation of downhole well tool assemblies, representatively flow control devices. In a described embodiment thereof, each actuator is positioned downhole and comprises a self-contained, closed circuit hydraulic system including an electrically operable double action primary pump drivingly coupled to an associated well tool assembly via a first hydraulic circuit, and an electrically operable switching pump coupled to the first hydraulic circuit via a second hydraulic circuit interposed therein and operative to selectively alter the control flow of hydraulic fluid to the well tool assembly in a manner reversing its operation. To provide for selective, more rapid control of the well tool assembly, a chargeable accumulator is connected to the hydraulic circuitry and is selectively and drivably communicatable with the well tool assembly.

摘要： A tie back receptacle extension includes a stinger having a smooth bore latch assembly carried thereon which includes a wedge device and a ramp, and the ramp outwardly displaces the wedge device to secure the stinger within a substantially smooth bore. A smoothbore latch assembly includes a spiral wound spring received in a recess, and the recess and the spring extending circumferentially relative to a stinger. A ramp outwardly displaces the spring relative to the recess in response to displacement of the spring relative to the ramp. A method of securing a stinger within a substantially smooth bore includes: providing a latch assembly on the stinger; inserting the stinger into the bore; and engaging the latch assembly with the bore, thereby securing the stinger relative to the bore, without the latch assembly engaging any recess formed in the bore.
