Valves for autonomous actuation of downhole tools

摘要: An autonomous valve includes a fluid-sensitive actuator operable to automatically actuate the in response being exposed target fluid. The fluid may be whose presence is generally undesirable production fluid, such as water, and actuated stop flow from an interval within wellbore that no longer expected produce hydrocarbon-bearing fluids. further protective layer disposed between inlet actuator, insoluble include swellable piston swells of soluble plug isolates hydraulic, closing until dissolved into electromechanical closes detecting using electronic sensor.
