Method and apparatus for drilling and servicing subterranean wells with rotating coiled tubing

摘要

A system is provided for drilling and/or servicing a well bore using continuous lengths of coiled tubing (14) in which a turntable assembly (18) rotates a coiled tubing reel (28) assembly and a counter balance system (26) about the well bore such that the coiled tubing is rotated while in the wellbore. A coiled tubing injector (22) may be provided on a separate turntable assembly or on the same turntable assembly as the reel assembly.
