摘要： A downhole shock absorber preferably is filled with well fluid in a chamber that is reduced in volume due to impact. A rupture disc can hold the initial non-compressible liquid charge until impact. Upon impact, the rupture disc breaks to allow the fluid to be forced through an orifice to absorb some of the shock that occurs when a string hits a fixed object after dropping in the wellbore. The nose of the shock absorber is a soft material that has voids so that the combination of the softness of the material and the voids allow the nose to reshape until it encounters a surrounding tubular wall and then to collapse inwardly into the voids, making it simple to remove. The nose is releasably mounted to the shock absorber so the two can separate if the nose gets stuck after impact.

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： The tool can run in and latch another tool such as a ball valve into a packer, for example. It has the capability of operating the valve while still engaged to the valve housing. Once the valve is operated and released a pressure test can be conducted while the tool is still engaged to the valve housing. After that a predetermined applied force allows release from the valve housing without the valve shifting mechanism still engaged. In a different configuration the tool can be a simple pulling tool to remove the valve housing without shifting it. The tool has a rotational lock to allow release from a packer by turning to the right. In another configuration it can be a latch tool for a production string that shifts the valve as it releases when the production string is pulled.

摘要： A valve for enabling communication between a first pressure and a second pressure including a piston member arranged in a housing. The piston member is movable between an open configuration and a closed configuration for selectively enabling communication between the first and second pressures. A control assembly is included for moving the valve to the open configuration. A first net pressure area is exposed to the first pressure and operatively arranged to urge the valve in a closing direction in response to the first pressure when the valve is in a closed configuration. A second net pressure area is exposed to the second pressure and operatively arranged to urge the valve in the closing direction in response to the second pressure when the valve is in a closed configuration. A method of operating a valve system is also included.

摘要： A shock absorbing system has a nose assembly that is formed to inwardly collapse on impact and is guided by a sleeve that can slide with the nose as the nose collapses or can extend for a portion of the length of the nose while being held fixed. In the latter instance the nose can have a leading end that has a biasing member in a resilient material so that on impact some of the shock is taken up by compression of the biasing member with subsequent extension of the biasing member retracting the resilient covering so that it is less likely to bind in the surrounding tubular. The leading end of the sleeve or the resilient material encasing the biasing member also soften the blow to a closed ball when the tool is dropped so that the ball surface is less likely to mar.
