摘要： 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.

摘要： A control system for a subsurface safety valve addresses normal open and closed operation and a failsafe operation if key system components fail. It features a single control line from the surface that splits at the subsurface safety valve and goes to one end of two discrete piston chambers that are aligned and isolated from tubing pressure. The piston in one chamber is larger than in the other and the pistons are connected for tandem movement. Each side of the unbalanced system's piston has a seal mounted to it and another for the rod attached to it that exits the chamber. A jumper line connects the chambers at a point between the seals in each chamber and features a large reservoir. The jumper line is filled with a compressible fluid. Fail safe closure of the valve occurs if any of the four seals fail.

摘要： A control system for a downhole tool, such as a subsurface safety valve, features an operating piston that is insensitive to tubing pressure in the valve. The hydrostatic forces from the single control line from the surface are significantly reduced with a branch line to a piston bottom that is slightly smaller than the piston top. A variable volume between piston seals is connected to a low pressure compressible fluid reservoir to permit piston movement. The piston can be modular to facilitate assembly or bore offsets in the valve body. Failsafe closure upon seal failures is contemplated.

摘要： Piston bore distortions in a sub-surface safety valve are reduced or eliminated when valve body is subjected to high working pressures. In one embodiment, a piston is disposed in a sleeve that is disposed in a piston bore. The bore can distort but the sleeve within will not distort to the point of losing sealing pressure around the piston. In another approach additional bore or bores are provided adjacent the piston bore to make the pin end of the connection for the valve housing more uniform in the region of the piston bore so that pressure loading does not result in sufficient distortion of the piston bore to lose the piston sealing relation in its bore.
摘要翻译：当阀体经受高工作压力时，减小或消除了表面安全阀中的活塞孔变形。在一个实施例中，活塞设置在设置在活塞孔中的套筒中。孔可以变形，但是套筒内部不会扭曲到活塞周围的密封压力降低的程度。在另一种方法中，邻近活塞孔设置附加的孔或孔，以使得在活塞孔的区域中的阀壳的连接的销端更均匀，使得压力负载不会导致活塞孔的足够的变形而损失其孔中的活塞密封关系。
