Downhole anchoring tools conveyed by non-rigid carriers |
摘要 |
An apparatus and method provides an anchor device for use in a wellbore that comprises an actuator assembly responsive to an actuating signal, an operator coupled to the actuator assembly, and an engagement member moveable to a set position by the operator when actuated by the actuator assembly to set the anchor device. The anchor device may be employed in various tool strings, such as a perforating tool string. In one arrangement, the anchor device provides an automated retraction mechanism that is activated after a predetermined delay. In another arrangement, a retract signal may be supplied to activate the retraction mechanism.
