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 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 wellbore. A coiled tubing injector may be provided on a separate turntable assembly or on the same turntable assembly as the reel assembly. A swivel support assembly may be provided for managing operation lines associated with the system.

主权项

1. A system for managing control lines associated with coiled tubing well operations equipment, comprising:
a floor having a platform that can rotate relative thereto, the platform having operations equipment thereon; a control line swivel that supports one or more operation equipment control lines above the floor; at least one control line extending between the swivel and well operations equipment on the platform for controlling operation of the equipment; a torque member having a first end coupled to the platform and a second end coupled to a rotatable portion of the swivel; a support member having a first end coupled to the floor and a second end coupled to a non-rotatable portion of the swivel; the swivel, torque member and support member configured such that as the platform rotates relative to the floor, the torque member causes the rotatable portion of the swivel to rotate therewith; and at least one adjustment member coupled to the support member for moving the swivel into and out of position.
