摘要:
A downhole tool includes a hydraulically operated actuation device to actuate the downhole tool and a control system that regulates flow of hydraulic fluid to the actuation device. The control system includes a pilot module and a power module. The power module has a first solenoid valve and a second solenoid valve fluidly coupled to a pressure source and a fluid return. The power module is fluidly coupled to the actuation device at an output line and a power line. A first power module check valve is arranged in the power line, a second power module check valve is arranged in a control pressure return line fluidly coupled to the fluid return, a first input communicates with the first solenoid valve, and a second input communicates with the second solenoid valve. A pilot-operated check valve is actuatable in response to a pilot signal to drain hydraulic fluid from the power module.
