Wireline Hydraulic Driven Mill Bottom Hole Assemblies and Methods of Using Same

摘要

A bottom hole assembly for engaging and removing an object within a wellbore comprises a cutting tool at a lower end. Continued engagement of the cutting tool with the object is facilitated by an axial compression device disposed within the bottom hole assembly below the anchor of the bottom hole assembly. The axial compression device comprises a compressed position and an expanded or extended position. As the object is being cut or abraded, the axial compression device moves from the compressed position toward the expanded position so that a continued downward force is transferred to the object by the bottom hole assembly.

主权项

1. A bottom hole assembly for running on a wireline into production tubing of a wellbore, the bottom hole assembly comprising:
an upper end having a wireline connector releasably secured to a wireline; a first packer disposed below the wireline connector; a first drain sub having a first drain sub port in fluid communication with an upper bore of the bottom hole assembly; an axial compression device disposed below the first packer, the axial compression device having a compressed position and an extended position; a hydraulically actuated motor disposed below the axial compression device; a ported sub disposed below the motor, the ported sub having a sub port; and a cutting tool disposed below the ported sub, the cutting tool operatively associated with the motor.
