摘要： A downhole valve apparatus including a force transmitter configured to move in an axial direction and a valve actuator configured to move in an axial direction. The valve actuator is independently movable relative to the force transmitter and physically isolated from the force transmitter. A first magnetic assembly is disposed at the force transmitter. A second magnetic assembly is disposed at the valve actuator. The first and second magnetic assemblies are configured to repel one another and cause the force transmitter to move the valve actuator when the force transmitter is moved toward the valve actuator.

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 valve for a line going to a subsurface safety valve can be blocked off with a valve that is initially held in a closed position. An upper spring pushes collets against a shoulder to keep a seal on a support assembly for the collets within an initial bore in a sealing relation. Application of pressure to the line urges the support assembly to move with respect to the collets and causes the collets to become unsupported. This initial movement of the support assembly is against a second spring that is weaker than the upper spring. The upper spring forces the collapsed collets into a smaller bore while the support assembly is retained against reverse movement at the urging of the second spring by a ratchet assembly. The seal is shifted into a bigger bore to allow flow through the valve and into or beyond the subsurface safety valve.

摘要： A tubing pressure insensitive actuator system includes a housing having a bore therein. A force transmitter is sealingly moveable within the bore, the force transmitter defining with the bore two fluid chambers. One of the fluid chambers is at each longitudinal end of the force transmitter. At least two seals are sealingly positioned between the housing and the force transmitter, with one of the seals isolating one end of the force transmitter from tubing pressure and another of the seals isolating another end of the force transmitter from tubing pressure. A method is also included.

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.
