| 摘要 |
The invention consists of a downhole data transmission line, and a method of making the same, having at least one polymeric or glass fiber, a first containment tube surrounding the fiber, a conductive material wrapped or braided around the first tube, a layer of insulating material covering the conductive material, and a second containment tube surrounding the insulating material. The downhole transmission line preferably uses optical fibers, a stainless steel first and metal alloy second tubes, copper braiding for the conductive material, thermoplastic for the insulating material, and a protective layer surrounding the outer second tube. A well for producing oil or gas from an oil or gas reservoir that includes the data transmission line and a system for sensing and recording physical parameters over an extended distance that includes the data transmission line are described. The invention also includes methods of using the data transmission line.
