摘要

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