Abstract
The present invention discloses a multichannel composite coiled tubing (CCT). The multichannel composite coiled tubing includes three inner pipes and an insulator, where the insulator is provided therein with a plurality of the inner pipes; the insulator is nested inside a sheath; a protective layer is welded outside the sheath; a compressive layer is welded outside the protective layer; a plurality of armored tubes are bonded to the outside of the compressive layer; a fiber layer is bonded to the outside of the armored tubes. In the present invention, the operation and test procedures are simple, the pressure is easy to measure, and a water injection additive can be easily selected to match different reservoirs. In addition, the coiled tubing is insulated, satisfying pressure transmission and logging through two cables. The compressive layer and the armored tube are convenient for extending the life of the tubing.
