摘要: A stroke control tool for controlling the position of a subterranean well hydraulically actuated double acting piston and cylinder actuator assembly. The tool includes hydraulic fluid measuring means positioned adjacent the well and is connected to the actuator by relatively inelastic hydraulic lines so that the volume of fluid communicating between the measuring means and the actuator can accurately be measured for determining the position of the actuator.
