Abstract

An embodiment of a method for manufacturing a cable, comprises providing a cable core comprising at least one conductor therein, extruding a stopping layer about at least the cable core, extruding a jacketing layer about the stopping layer, and cabling at least one armor wire layer about the jacketing layer to form the cable, wherein the stopping layer comprises a polymer layer configured to mechanically and thermally protect the cable core.

Claims (17)

1. A method for manufacturing a cable, comprising:

providing a cable core comprising at least one conductor;

extruding an inner stopping layer about at least the cable core, wherein the inner stopping layer comprises a polymer layer configured to mechanically and thermally protect the cable core;

extruding a first jacketing layer about the stopping layer; and

cabling a first armor wire layer about the first jacketing layer; extruding an outer stopping layer over the first armor wire layer, and cabling a second armor wire layer about the outer stopping layer.

2. The method of claim 1 wherein extruding an inner stopping layer comprises extruding a polymeric layer of Polyarylether ketone families comprising, PolyEtherEtherlKetone (PEEK), PolyEtherKetone (PEK), PolyKetone (PK), or polyaryletherketone (PAEK), and combinations thereof.

3. The method of claim 1 wherein extruding a first jacketing layer comprises extruding a fluoropolymer, wherein the fluropolymer comprises ethylene-tetrafluoroethylene copolymer (ETFE), TFE/Perfluoromethylvinylether Copolymer (MFA), ethylene-chlorotrifluoroethylene copolymer (ECTFE), perfluoroalkoxy resin (PFA), fluorinated ethylene propylene copolymer (FEP), polytetrafluoroethylene (PTFE), and combinations thereof.

4. The method of claim 1 wherein cabling comprises at least partially embedding the first armor wire layer into the first jacketing layer.

5. The method of claim 4 wherein embedding comprises embedding the first armor wire layer into the first jacketing layer while the first jacketing layer is soft.

6. The method of claim 1 further comprising extruding a jacketing layer about the first armor wire layer.

7. The method of claim 6 further comprising extruding at least one jacketing layer over the outer stopping layer.

8. The method of claim 1 wherein cabling comprises cabling at least one of a solid armor wire layer and a stranded armor wire layer.

9. The method of claim 1 wherein a one of extruding an inner stopping layer and extruding a first jacketing layer comprises extruding an amended polymer material, wherein the polymer material is amended with a plurality of strengthening members.

10. The method of claim 9 wherein the strengthening members comprise at least one of a wear-resistant particle and a fiber.

11. The method of claim 1 wherein providing a cable core comprises providing a one of a monocable, a coaxial cable, a triad cable, a quad cable, and a heptacable.

12. The method of claim 1 wherein the cable comprises a wireline cable configured for use in a wellbore penetrating a subterranean formation.

13. The method of claim 1 wherein the outer stopping layer is configured to protect the cable core from damage at an exposure about 500 to about 600 degrees Fahrenheit.
