    • 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.
    • 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。

    • A pressure equalizing tool can be run into a downhole tool on wireline or coiled tubing preferably and temporarily secured before being actuated to separate two components in a downhole tool that are in a sealing relation but are configured to be temporarily movable so as to allow pressure equalization before the downhole component is actuated. Once pressure is equalized the equalizing tool is released, usually with an applied pick up force and the downhole tool being equalized as to differential pressure can be operated with the preexisting actuation parts that are on the downhole tool. In a preferred embodiment the downhole tool is a ball valve and the equalizing tool is temporarily secured to the ball valve housing to temporarily part the ball from the uphole seat to equalize an annular space around the ball with tubing pressure. The ball is allowed to go back to contact with the seat when the equalizing tool is released and removed from the tubing.
    • 压力平衡工具可以在有线或连续油管上运行到井下工具中,优选地并且暂时固定在被致动之前,以分离处于密封关系中的井下工具中的两个部件,但被构造成可临时移动以允许压力均衡 在井下部件被致动之前。 一旦压力相等,通常用施加的拾取力来释放均衡工具,并且井下工具可以与在井下工具上的预先存在的致动部件一起操作,以便差压。 在优选实施例中,井下工具是球阀,并且均衡工具临时固定到球阀壳体上,以使球从井上座部临时地分开,以使球的环形空间与管道压力相等。 当平衡工具释放并从管道中取出时,允许球回到与座椅接触。

    • 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.
