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.

La présente invention concerne un système destiné au forage et/ou à la desserte d'un puits foré en utilisant des longueurs continues de tubulure bobinée (14), dans lequel un ensemble à plateau tournant (18) fait tourner autour du puits foré un ensemble bobine à tubulure bobinée (28) et un système de contrepoids (28), de façon que la tubulure bobinée tourne pendant qu'elle est dans le puits foré. L'invention peut comporter un injecteur de tubulure bobinée (22) sur un ensemble plateau tournant distinct, ou sur le même ensemble plateau tournant que l'ensemble bobine.
