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： A combination penetration tool for access to the control system of a subsurface safety valve also has a lockout for the flapper that operates by latching into a nipple profile near its upper end as a series of collet fingers pass through a sleeve that is held in the locked position on the valve housing. One or more dogs on the collet fingers line up with the flapper already pushed open by the advancing collet fingers to push the flapper further back. A second series of dogs get past the sleeve after moving through it. With a jar up force the second series of dogs overcomes a lock on the sleeve and shifts the sleeve to overlap the open flapper and allow the lock ring that moves with the sleeve to latch into the housing. The second series of dogs is sheared off but retained by the tool for removal from the well. The penetrator portion of the tool is a known device that preferably works by jarring up.

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。
