Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
103 words
A device for carrying out measurings or interventions in a drilled well (4), comprising a rod (2), or stem, and a measuring or intervention instrument (3), said instrument being arranged at a lower end of said rod, said rod exhibiting a flexural elasticity and a compressive rigidity, characterized in that said rod comprises at least one adapted energy or information transfer line such as an electric, fluid or optical line, said line being embedded in said rod, said rod being adapted for being wound round at least one reel, and in that said rod comprises a composite or a non composite polymeric material.
Claim 2
Independent Claim
103 words
A device for carrying out measurings or interventions in a drilled well (4), comprising a rod (2), or stem, and a measuring or intervention instrument (3), said instrument being arranged at a lower end of said rod, said rod exhibiting a flexural elasticity and a compressive rigidity, characterized in that said rod comprises at least one adapted energy or information transfer line such as an electric, fluid or optical line, said line being embedded in said rod, said rod being adapted for being wound round at least one reel, and in that said rod comprises a composite or a non composite polymeric material.
Claim 3
Dependent Claim
14 words
A device as claimed in claim 1, wherein said rod (2) is substantially solid.
Claim 4
Independent Claim
48 words
A device as claimed in any one of claims 1 and 2, said rod comprising a neutral fiber along which no tensile or compressive stress appears when said rod is subjected to a flexion, wherein said transfer line is substantially arranged in the proximity of said neutral fiber.
Claim 5
Independent Claim
20 words
A device as claimed in any one of claims 1 to 3, wherein said rod is adapted for withstanding torsion.
Claim 6
Independent Claim
31 words
A device as claimed in any one of claims 1 to 4, wherein the composite material consists of glass, carbon or polyaramid fibers embedded in a thermoplastic or thermosetting resin matrix.
Claim 7
Dependent Claim
19 words
A device as claimed in claim 5, wherein said composite material comprises glass fibers embedded in an epoxy resin.
Claim 8
Independent Claim
37 words
A device as claimed in any one of claims 1 to 4, wherein the polymeric material devoid of reinforcing elements is selected from the elements of the following polymer group : polyamide, vinylidene polyfluoride, high-density cross-linked polyethylene.
Claim 9
Independent Claim
40 words
A device as claimed in any one of claims 1 to 7, wherein the nature of the material constituting the outer part of rod (2) is adapted for reducing the friction between said rod and the wall of well (9).
Claim 10
Independent Claim
23 words
A device as claimed in any one of claims 1 to 9, wherein said rod (2) is manufactured by a continuously producing machine.
Claim 11
Independent Claim
22 words
A device as claimed in any one of claims 1 to 9, wherein said rod (2) is made by extrusion or pultrusion.
Claim 12
Dependent Claim
27 words
A device as claimed in claim 1, wherein said rod (2) is hollow and wherein said line (19, 20) is embedded in the thickness of said rod.
Claim 13
Independent Claim
24 words
A device as claimed in any one of claims 1 to 11, wherein the outer part of said rod (2) comprises an anti-abrasion agent.
Claim 14
Dependent Claim
45 words
A process utilizing the device claimed in any one of claims 1 to 12, the rod being wound round a reel, wherein, when the rod is unwound from the reel to be introduced into said well, said rod is substantially only subjected to elastic deformations.
Claim 15
Dependent Claim
21 words
Application of the device claimed in any one of claims 1 to 12 to a well for producing a petroleum effluent.
