Abstract
Provided is a method of manufacturing a downhole cable, the method including, forming a helical shape in an outer circumferential surface of a metal tube, the metal tube having a fiber element housed therein, and stranding a copper element in a helical space formed by the metallic tube. Also provided is a downhole cable including, a metallic tube having a helical space in an outer circumferential surface thereof, wherein the metallic tube has a fiber element housed therein, and a copper element disposed in a helical space formed by the steel tube. Double-tube and multi-tube configurations of the downhole cable are also provided.
Claims8
A method of manufacturing a cable, the method comprising:
- stranding one or more copper elements in a helical space in an outer circumferential surface of a metal tube,
- wherein the helical space and the metal tube are in a same plane when viewed from a cross-section of the cable along a longitudinal axis of the cable.
A cable comprising:
- a metal tube;
- and
- one or more copper elements stranded in a helical space in an outer circumferential surface of the metal tube,
- wherein the helical space and the metal tube are in a same plane when viewed from a cross-section of the cable along a longitudinal axis of the cable.
