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 (20) from the surface that splits at the subsurface safety valve and goes to one end of two discrete piston chambers (64, 46) that are aligned and isolated from tubing pressure. The piston (36) in one chamber is larger than in the other and the pistons (36, 52) are connected for tandem movement. Each side of the unbalanced system's piston has a seal mounted to it (38, 54) and another for the rod (40, 56) attached to it that exits the chamber. A jumper line (68) connects the chambers (48,62) at a point between the seals in each chamber and features a large reservoir (70). The jumper line (68) is filled with a compressible fluid. Fail safe closure of the valve occurs if any of the four seals fail.

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 subsurface safety valve is provided comprising a housing having a main bore and a piston bore in a wall thereof. The piston bore extends from a connection adapted to receive a control line. The subsurface safety valve further comprises a sleeve wholly within in said piston bore and further 5 containing a piston therein. The sleeve extends for the length of the bore occupied by the piston.

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 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.
