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： 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 downhole tool (100) for wellbore operations comprises a substantially tubular member (130) that is operably positionable in the wellbore and a rotation member (110) that is rotatably disposed within the substantially tubular member (130). The rotation member (110) has a passageway (112) through which objects may pass into the wellbore. The rotation member (110) rotates about an axis of rotation (x) that is substantially perpendicular to the longitudinal axis (y) of the substantially tubular member (130) in response to fluid flow through the passageway (112). The rotation member (110) has magnetic properties such that rotation of the rotation member (110) generates a magnetic field that produces useable power.

摘要： A power generating system (100) for a downhole operation (10) having production tubing (40) in a wellbore (12) includes a magnetized rotation member (110) coupled to the wellbore (12) within the production tubing (40), the rotation member (110) having a passageway (112) through which objects, such as tools, may be passed within the production tubing (40). Support braces (170, 172) couple the rotation member (110) to the production tubing (40) and allow the rotation member (110) to rotate within the production tubing (40). Magnetic pickups (150, 152) are predisposed about the rotation member (110) within the wellbore (12) and a power conditioner (200) is provided to receive currents from the magnetic pickups (150, 152) for storage and future use. The rotation member (110) rotates due to the flow of fluid, such as crude oil, through the production tubing (40) which causes the rotation member (110) to rotate and induce a magnetic field on the magnetic pickups (150, 152) such that electrical energy is transmitted to the power conditioner (200), the power conditioner able to store, rectify, and deliver power to any one of several electronic components within the wellbore (12).

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 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.
