Abstract

A tubing for an electric submersible pump (ESP) for oil production. Cables are wrapped outside a first outer sheath at equal intervals; an inner side of the cable is covered with an insulating layer; an inner side of the insulating layer is covered with an aluminum tape; and a conductor is nested inside the aluminum tape. The inner pipe is combined with the cable to meet the oil production requirement of a coiled tubing (CT) and solve a power transmission problem of the submersible pump. The first outer sheath and a second outer sheath ensure that the tubing has a high bearing capacity and stability inside. A first steel belt and a second steel belt ensure a high resistance to pulling and deformation inside the tubing in use.
