Downhole force generator and method for use of same

摘要

A downhole force generator ( 60 ) adapted to be moved to a target location within a wellbore ( 70 ) for interaction with a well tool ( 74 ) previously positioned in the wellbore ( 70 ) comprises a downhole power unit ( 62 ) having a moveable shaft ( 68 ). An anchor ( 64 ) is operably associated with the downhole power unit ( 62 ). The anchor ( 64 ) has an anchoring configuration and a running configuration. In the anchoring configuration, the anchor ( 64 ) longitudinally secures the downhole force generator ( 60 ) within the wellbore ( 70 ). An operating tool ( 66 ) is operably associated with the downhole power unit ( 62 ) and is operably engageable with the well tool ( 74 ) such that when the operating tool ( 66 ) is operably engaged with the well tool ( 74 ) and the anchor ( 64 ) is in the anchoring configuration, movement of the moveable shaft ( 68 ) will transmit a force to the well tool ( 74 ).
