发明名称 MULTI-POSITION TOOL ACTUATION SYSTEM
摘要 A technique facilitates control over a multi-position well tool. A hydraulic control module may be engaged with a multi-position well tool for controlling actuation of the multi-position well tool through a plurality of actuation positions. The multi-position well tool is moved through the plurality of actuation positions by applying pressurized fluid through a first control line. A metering piston is uniquely arranged within the hydraulic control module to control actuation of the multi-position well tool from an initial actuation position through a plurality of incremental actuation positions. Additionally, a single pressurization of actuation fluid delivered through a second control line may be used to return the multi-position well tool back to the initial actuation position from any incremental position.
