Abstract

A system and method for a down-hole cable with a liquid bonding system is provided. Generally, the system contains at least one insulated conductor fully insulated by an insulation coating. An armor shell is positioned exterior to the insulating coating and fully surrounds the insulated conductor. A liquid bonding material is applied between at least a portion of an exterior surface of the insulation coating and at least a portion of an interior surface of the armor shell, wherein the liquid bonding material creates a bond between the insulation coating and the armor shell.

Claims

1. A down-hole cable comprising:

at least one insulated conductor fully insulated by an insulation coating;

an armor shell positioned exterior to the insulating coating and fully surrounding the insulated conductor; and

a liquid bonding material applied between at least a portion of an exterior surface of the insulation coating and at least a portion of an interior surface of the armor shell, wherein the liquid bonding material creates a bond between the insulation coating and the armor shell.

2. The down-hole cable of claim 1, further comprising a gas pocket located proximate to at least one of the insulated conductor and the liquid bonding material.

3. The down-hole cable of claim 1, wherein the armor shell is positioned substantially concentric to the at least one insulated conductor.

4. The down-hole cable of claim 1, wherein the armor shell is positioned off-centered from to the at least one insulated conductor.

5. The down-hole cable of claim 1, wherein the liquid bonding material fully engulfs an interior portion between the exterior surface of the insulation coating and the interior surface of the armor shell.

6. The down-hole cable of claim 1, wherein the bond between the insulation coating and the armor shell further comprises an adhesive bond.

7. The down-hole cable of claim 1, wherein the at least one insulated conductor further comprises a plurality of insulated conductors, wherein each of the plurality of insulated conductors is individually and fully insulated by the insulation coating.

8. The down-hole cable of claim 7, wherein each of the plurality of insulated conductors includes at least one identification marking.

9. The down-hole cable of claim 1, wherein the armor shell is connected to at least one anchoring structure.

10. The down-hole cable of claim 1, wherein the liquid bonding material further comprises an epoxy adhesive having an epoxide resin and a polyamine hardener.

11. The down-hole cable of claim 1, wherein the liquid bonding material retains the at least one insulated conductor in a substantially stationary position with respect to the armor shell.

12. The down-hole cable of claim 1, wherein the liquid bonding material applies a non-compressive force on the insulated conductor.

13. A method of making a down-hole cable, the method comprising the steps of:

providing at least one insulated conductor fully insulated by an insulation coating;

positioning an armor shell exterior to the insulation coating, wherein the minor shell fully surrounds the insulated conductor; and

applying a liquid bonding material between at least a portion of an exterior surface of the insulation coating and at least a portion of an interior surface of the armor shell, wherein the liquid bonding material creates a bond between the insulation coating and the armor shell.

14. The method of making a down-hole cable of claim 13, further comprising the step of enclosing a gas pocket interior to the armor sheath and proximate to at least one of the insulated conductor and the liquid bonding material.

15. The method of making a down-hole cable of claim 13, wherein the step of applying a liquid bonding material between at least a portion of the exterior surface of the insulation coating and at least a portion of an interior surface of the armor shell further comprises fully engulfing an interior portion of the cable positioned between the exterior surface of the insulation coating and the interior surface of the armor shell.

16. The method of making a down-hole cable of claim 13, further comprising the step of connecting the armor shell to at least one anchoring structure.

17. The method of making a down-hole cable of claim 13, further comprising the step of applying a non-compressive force on the insulated conductor by the liquid bonding material.

18. The method of making a down-hole cable of claim 13, further comprising the step of curing the liquid bonding material with at least one of a heated application, an elapsed period of time, a chemical reaction, an ultraviolet light application and a moisture curing application.

19. The method of making a down-hole cable of claim 13, further comprising the step of retaining the at least one insulated conductor in a substantially stationary position with respect to the armor shell using the liquid bonding material.

20. A down-hole cable for use in a substantially vertical position, the down-hole cable comprising:

at least one insulated conductor fully insulated by an insulation coating;

an armor shell positioned exterior to the insulating coating and fully surrounding the insulated conductor; and

an epoxy-based bonding material positioned between an exterior surface of the insulation coating and an interior surface of the armor shell, the bonding material non-compressively securing the insulated conductor to the interior surface of the armor shell with an adhesive bond, wherein the at least one insulated conductor is retained from movement respective to the armor shell by the adhesive bond when the down-hole cable is positioned substantially vertical.
