Abstract
Abstract A crush and abrasion resistant, sealed, impervious, flexible protective jacket assembly for oil and gas wells containing a plurality of electrical and/or fluid conductors that are oriented in linear, spaced, parallel relation. A pair of elongated protective metal sheets define elongated conductor grooves. The metal sheets are joined by welding to define a plurality of elongated chambers containing one or more of the conductors. The chambers are sealed from the atmosphere and may be filled with a non-gaseous dielectric material to prevent the development of corona discharge that might cause deterioration of the protective jacket assembly. The configuration of the sheets of protective material is such that the development of corona discharge is resisted. A pair of metal longitudinal structural elements are attached at opposed sides of the protective jacket assembly and prevent damage thereto by abrasion, crushing, bending, etc., and provide sufficient tensile strength so that the protective jacket assembly will support its entire length.

An uninterrupted, liquid and gas impervious, crushed and abrasive resistant seal protective jacket assembly having sufficient tensile strength to support the weight of long lengths thereof, said protective jacket assembly comprising (a) elongated, uninterrupted conductor means extending the length of said protective jacket assembly; (b) first and second elongated, uninterrupted metal sheets defining a groove extending the length of said protective jacket assembly; (c) a pair of spaced welds securing said metal sheets in assembly along opposed sides thereof, said welds and said groove cooperating to define sealed metal sheath means forming an elongated sealed conductor passage extending the length of said protective jacket assembly, said conductor means being located within said elongated sealed conductor passage of said sealed metal sheath means; (d) a pair of uninterrupted longitudinal metal structural elements being positioned at opposed sides and externally of said metal sheath and being structurally interconnected with at least one of said metal sheets, said longitudinal structural elements having at least a part thereof exposed for guiding and for protective contact with other structures as said protective jacket assembly is moved linearly relative to said other structures, said longitudinal structural elements preventing crushing and abrading of said metal sheath means and said conductor means when in contact with said other structures, said longitudinal structural elements being of sufficient tensile strength to support the weight of said protective jacket assembly and included conductor means.
Claim 68
Dependent Claim
47 words
The sealed protective jacket assembly as recited in claim 58 wherein said elongated, uninterrupted conductor means extending the length of said protective jacket assembly comprise a plurality of conductors disposed contiguously together within said sealed metal sheath means and substantially linearly between said longitudinal metal structural elements.
Claim 69
Dependent Claim
25 words
The sealed protective jacket assembly as recited in claim 59 wherein the space between said conductors and said sheath is filled with a dielectric medium.
Claim 70
Dependent Claim
54 words
The sealed protective jacket assembly as recited in claim 58 wherein said elongated, uninterrupted conductor means extending the length of said protective jacket assembly comprises a plurality of conductors extending in twisted configuration within the length of said sealed conductor passage and in contiguous relationship within said walls of said sealed metal sheath means.
Claim 71
Dependent Claim
25 words
The sealed protective jacket assembly as recited in claim 61 wherein the space between said conductors and said sheath is filled with a dielectric medium.
