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： A system is provided for switching between redundant control systems for a subsurface safety valve (SSV) while being able to isolate the closure spring from hydrostatic pressure in the control line of the system that is not being used. There are two control lines that connect to discrete operating pistons that are both coupled to the flow tube. Each operating piston is connected to a control rod with the control rods terminating near opposed ends of a pivoting member. Pushing down on one rod pushes up on the other rod so that the other rod is held supported and the hydrostatic pressure in its associated control line doesn't affect the force needed by the closure spring to close the SSV. Releasing control line pressure puts the system in neutral to allow either of the systems to be reselected.
摘要翻译：提供一种用于在地下安全阀（SSV）的冗余控制系统之间切换的系统，同时能够将闭合弹簧与未使用的系统的控制线中的静水压力隔离开。有两条连接到离散的操作活塞的控制线都连接在流管上。每个操作活塞连接到控制杆，控制杆在枢转构件的相对端附近终止。将另一根杆推到另一根杆上，将另一根杆保持在支撑状态，其关联控制线中的静水压力不会影响闭合弹簧关闭SSV所需的力。释放控制线压力使系统处于中立状态，以允许任何一个系统被重新选择。

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。

摘要： A tool is preferably landed in a downhole profile commonly found adjacent to seal bores. Once landed, preferably with coiled tubing, pressure in the coiled tubing triggers a switch to power a motor to rotate a polishing cylinder that features spirally wound vanes. A reservoir of resin or other repair material is connected to an injection pump to deliver the material as the vanes are rotating. The material exits between the vanes so that the vanes can spread it and work it into surface irregularities. After the material is sufficiently spread into voids and the requisite polishing completed, the seal bore is again ready to accept a tool in a sealed relationship.

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.
