ACTUATION SYSTEM FOR WELL TOOLS |
摘要 |
A technique facilitates control over one or more well tools coupled to one or more corresponding control modules. Actuation of the control modules and the well tools may be achieved with three control lines connected to the one or more control modules. Transitioning of the control modules to sequential stages and the consequent actuation of the corresponding well tools is achieved by applying a single pressure level selectively through the three control lines. |
