摘要:
A tubing pressure insensitive failsafe wireline retrievable safety valve including a tool housing, a flow tube disposed within the tool housing, an actuation piston disposed in the tool housing and operably connected to the flow tube, the actuation piston having an actuation pressure side and a relatively lower pressure chamber side, a fluid pathway between a potential leak site for the valve and the relatively lower pressure chamber side of the piston. A borehole system having a tubing pressure insensitive failsafe wireline retrievable safety valve. A tubing pressure insensitive failsafe wireline retrievable safety valve.
