Composite coiled tubing-cable include outer tube, power cable and signal cable;Both power and signal cables are circular;The power cable and signal cable are separated from each other and encapsulated in the outer tube through the filling layer. Armor layer is arranged between the filling layer and the outer pipe.

The composite coiled tubing-cable integrates the coiled tubing, oil pump cable and signal cable and the problem of oil exploitation and drilling has been solved effectively.

By adopting the above scheme, the cables in the coiled tubing-cable have less interference with each other, which is convenient to be closed and released, and the high insulation strength and high temperature resistance are better. It can improve the service life of coiled tubing-cable under bad working conditions.
