Long Length Electro Coiled Tubing and Method of Manufacturing Same

摘要

Electro coiled tubing (ECT) can be utilized to provide electrical power to equipment in wells. A long length of ECT is provided with protrusions welded on the inside of the tubing at selected intervals to form support shoulders. Anchors with a load shoulder are attached to the electrical cable enclosed in the tubing such that the load shoulder contacts the support shoulder created by the welded protrusion. The weight of the electrical cable can then be transferred to the tubing via the contact between the load shoulder and the support shoulder. The protrusions are welded to the tubing and the anchors are attached to the cable during the manufacturing process.
