APPARATUS & METHOD FOR RUNNING TUBULARS

摘要

A method and apparatus for running tubular into a well bore for use with a top drive or power swivel comprising a make-up assembly with inner and outer members one of which has an array of ramped surfaces while the other is a outer or outer cage with slipper-gripper blocks and apertures wherein relative movement of the members urges the slipper-gripper block to protrude radially through the apertures to engage a tubular internally or externally. Also provided is an elevator assembly with elevator links and transfer elevators to position tubular for engagement by the make-up assembly.
