Automated Blowout Preventer Control and Testing System

摘要

A method and apparatus for testing a blowout preventer which includes a plurality of safety devices and an assembly of fluid control valves that are remotely actuatible to an open and closed position for controlling flow of drilling fluids into the well includes a hydraulic power unit control station for remotely and selectively actuating one or more safety devices and fluid control valves to a test orientation. A hydrostatic test system supplies fluid under first and second test pressure and documents any pressure loss due to fluid leaks within the closed system.

1. A method of conducting a pressure test for a blowout preventer which includes a plurality of safety devices operated by hydraulic pressure and for an assembly of fluid control valves and conduits for directing pressurized drilling fluid into or out of a wellbore, the fluid control valves being remotely actuated to an open or closed position comprising;
a) determing a test plan for testing isolated portions of the blowout preventer and fluid control valves and conduits, b) causing pressurized fluid from an hydraulic power unit to operate one or more of the safety devices within the blowout preventer according to the test plan, c) remotely actuating one or more of the fluid control valves to a closed or open position according to the test plan, and d) applying a first fluid test pressure to the blowout preventer and to the assembly of fluid control valves and conduits via a hydraulic test system.
