发明名称 TUBING HANGER RUNNING TOOL WITH INTEGRATED PRESSURE RELEASE VALVE
摘要 A system, in certain embodiments, includes a subsurface safety valve (SSV) biased toward a closed position, and configured to open by application of hydraulic pressure. The system also includes a tubing hanger running tool (THRT), including a conduit in fluid communication with the SSV, and a pressure release valve fluidly coupled to the conduit. The pressure release valve is configured to maintain sufficient hydraulic pressure within the conduit to hold the SSV in an open position while the pressure release valve is in a closed position.
