Rotary coil tubing drilling and completion technology

摘要

An apparatus for performing a drilling operation or a non-drilling wellbore operation may include a string that has a rigid tubular, a connector coupled to the rigid tubular, a non-rigid tubular coupled to the connector; and at least one motor positioned along the string. In some embodiments, a plurality of motors may be positioned along the string to rotate one or both of the non-rigid tubular and a drill bit connected to the string. In some embodiments, the connector may be configured to release the non-rigid tubular from the rigid tubular and thereby leave the non-rigid tubular in the wellbore.
