摘要： A tubing pressure insensitive, pressure compensated actuator system includes a housing having a bore therein. A force transmitter sealingly moveable within the bore. The force transmitter defining with the bore two fluid chambers. The two fluid chambers being in fluid communication with each other, one at each longitudinal end of the force transmitter. An activator in one or both of the two fluid chambers and operatively connected to the force transmitter. At least two seals sealingly positioned between the housing and the force transmitter. One of the seals disposed near one end of the force transmitter and another of the seals disposed near another end of the force transmitter. A separate compensation piston disposed in the housing so as to expose one end of the compensation piston to tubing pressure and to expose the other end of the compensation piston to a fluid volume including the fluid chambers. Also included is a method for reducing force requirements of an actuator.

摘要： A ball type downhole barrier valve capable of bidirectional sealing features a ball rotating on its axis to open or close with control line pressure to an actuating rod piston assembly. The ball is also shiftable to a locked open position. A cage surrounds the ball and retains opposed seats to it. The cage is made from one piece and tangential holes are drilled and tapped before the piece is longitudinally split with a wire EDM cutting technique. Fasteners to rejoin the cut halves properly space them to the original one piece internal dimension. Auxiliary tools allow determination of spacing of internal components so that a desired spring preload on the seats against the ball can be achieved. Seals on the sleeves that form ball seats help prevent leakage due to ball distortion at high differential pressures when the valve is closed.
摘要翻译：一种能够双向密封的球形井下阻挡阀，其特征在于，球体在其轴线上旋转，以通过控制管线压力打开或关闭致动杆活塞组件。球也可以移动到锁定的打开位置。一个笼子围绕球并保留相对的座位。保持架由一件制成，并且在利用电火花线切割技术纵向分开之前，钻出并攻丝切向孔。紧固件重新加入切割的半部分，将它们适当地放置在原来的一块内部尺寸上。辅助工具允许确定内部部件的间距，从而可以实现座椅上抵靠球的期望弹簧预加载荷。当阀门关闭时，形成球座的套筒上的密封件有助于防止高压差时由于球变形而造成的泄漏。

摘要： A downhole ball valve is mounted n a string and features a rotating ball that turns on its axis as it is held against an upstream and a downstream seal by a cage. The cage accepts a slide that engages the ball off-center to rotate it between the open and closed positions. The slide is operated by a sleeve attached to a piston assembly. The sleeve is mechanically operated in opposed directions such as by a wireline shifting tool. Differential pressure on a closed ball does not affect the actuation piston because pressure across the actuating piston is balanced while holding pressure differential across the closed ball. A check valve allows the actuation piston to be in pressure balance as the ball stays closed.
摘要翻译：一个井下球阀安装在一个绳子上，并具有一个旋转的球，当一个保持架保持在上游和下游的密封位置时，旋转的球将其转动。笼子接受一个滑块，使其偏离中心，使其在打开和关闭位置之间旋转。滑块由附接到活塞组件的套筒操作。套筒通过例如通过电缆移位工具在相反的方向上机械操作。封闭的球上的差压不会影响致动活塞，因为在保持闭合球的压力差的同时平衡致动活塞上的压力。止回阀允许致动活塞在球保持关闭时处于压力平衡。
