DOWNHOLE ANCHORING TOOLS CONVEYED BY NON-RIGID CARRIERS

摘要

An apparatus and method provides an anchor device (18) for use in a wellbore (10) that comprises an actuator assembly (104) responsive to an actuating signal, an operator coupled to the actuator assembly (104) and an engagement member moveable to a set position by the operator when actuated by the actuator assembly (104) to set the anchor device (18). The anchor device (18) may be employed in various tool strings, such as a perforating tool string (14). In one arrangement, the anchor device (18) provides an automated retraction mechanism that is activated after a predetermined time delay. In another arrangement, a retract signal may be supplied to activate the retraction mechanism (152).
