COILED TUBING AND DRILLING SYSTEM

摘要

A technique facilitates combined drilling and coiled tubing operations from a single bed (22) of a rig. A mast (32) is mounted to the bed, and a coiled tubing injector (44) is connected to the mast. The coiled tubing injector is able to move coiled tubing (54) into and out of a wellbore. A starter head (66) also is mounted to the mast. The starter head is rotatable to make and break connections of tool string components. However, the starter head generally is rotationally stationary during drilling operations.
