摘要：
A method for positional control of an actuator includes applying pressure to both an input line and an output line connected to the actuator and then releasing a predetermined volume of fluid from the output line, thereby displacing a piston of the actuator a corresponding predetermined distance. A system for positional control of an actuator includes the actuator included in a well tool positioned in a well; the input line connected to the actuator and extending to a remote location; the output line connected to the actuator and extending to the remote location; and a fluid volume measurement device connected to the output line at the remote location. The fluid volume measurement device is operative to meter the predetermined volume of fluid from the output line.
