System and method for formation isolation |
摘要 |
A technique employs a formation isolation valve that utilizes a ball rotatably mounted within a valve housing. The valve is designed to enable rotation of the ball about a fixed axis without translation of the ball. Rotation of the ball is achieved by connecting an arm to the ball at a position offset from the axis of rotation. A movable mandrel also is connected to the arm to enable selective actuation of the ball. |
