Abstract
The utility model relates to an anticorrosive load-bearing detecting cable and belongs to the cable manufacture technical field. The utility model consists of a conductive layer, a conductive core, a cable armouring layer and an oil resistant anticorrosive layer, wherein, the conductive layer is formed by copper wires being twisted with each other; the conductive core made of insulating materials is coated on the outside of the conductive layer; a layer of steel wires is winded on the conductive core or a twisted body of the conductive core in the forward direction; a layer of steel wires is winded on the conductive core or a twisted body of the conductive core in the reverse direction; the two layers of steel wires form the cable armouring layer; the oil resistant anticorrosive layer made of oil resistant anticorrosive materials is coated on the outside of the cable armouring layer. Compared with the prior art, the anticorrosive load-bearing detecting cable of the utility model has the characteristics that: the design is reasonable; the manufacturing cost is low; the cable can be used in an oil well for a long time and can not be corrupted, etc.
Description
(1) technical field
The utility model relates to a kind of cable, specifically a kind of can be in the medium-term and long-term work of oil well and can be by the charge bearing detecting cable of well corrosion.
(2) background technology
Present charge bearing detecting cable all is to constitute the armor layer by the two-layer steel wire that rightabout twines usually, is wrapped in lead in the armor layer and constitutes cable.The steel armour of this charge bearing detecting cable is exposed in the well liquid usually in when well logging, because well liquid contains and be corrosive, the damage that will be corroded after using after a while of steel armour loses cable steel armour to hold lotus to act on, and causes cable to scrap.In other words the charge bearing detecting cable of prior art be used to log well all right, if but be used for for a long time the down-hole fixedly lay basic through can't stand the corrosion of well liquid.
(3) summary of the invention
Technical assignment of the present utility model is at the deficiencies in the prior art, provides a kind of and can effectively overcome the be corroded anticorrosion charge bearing detecting cable of problem of prior art charge bearing detecting cable in well.
The technical scheme that its technical problem that solves the utility model adopts is:
This anticorrosion charge bearing detecting cable, comprise conductive layer, conductor wire core, cable sheath and oil resistance anticorrosion layer, conductive layer forms by copper wire is stranded, the outside of conductive layer is extruded with the conductor wire core that insulating material forms, the intertwist body of conductor wire core or conductor wire core is outside equipped with cable sheath, and cable sheath extrudes the oil resistance anticorrosion layer that one deck oil resistant resistant material is made outward.The manufactured materials of this oil resistance anticorrosion layer can be fluoroplastics, also can be polypropylene, also can be rubber.Can extrude one deck oil resistant resistant material with after a common core or the multicore charge bearing detecting cable process oil removing baking, require evenly closely knit airtight getting final product of external diameter rounding.
Above-mentioned anticorrosion charge bearing detecting cable, its cable sheath is combined by layer of steel wire and the reverse layer of steel wire of twining that forward twines.
Anticorrosion charge bearing detecting cable of the present utility model compared with prior art, the beneficial effect that is produced is: reasonable in design, simple in structure, low cost of manufacture, can long-term work in oil well, and can not be corroded.
(4) description of drawings
Accompanying drawing 1 is a cross sectional representation of the present utility model.
(5) embodiment
Below in conjunction with explaining below 1 pair of anticorrosion charge bearing detecting cable work of the present utility model of accompanying drawing.
As shown in Figure 1, anticorrosion charge bearing detecting cable of the present utility model, its structure is to be made of conductive layer 1, conductor wire core 2, cable sheath 3 and oil resistance anticorrosion layer 4, conductive layer 1 forms by copper wire is stranded, the outside of conductive layer 1 is extruded with the conductor wire core 2 that insulating material forms, and the outer forward of the intertwist body of conductor wire core 2 or conductor wire core 2 twines layer of steel wire, oppositely twines layer of steel wire again, two-layer steel wire forms cable sheath 3, the cable sheath 3 outer oil resistance anticorrosion layers 4 that are extruded with.
Its processing and fabricating of anticorrosion charge bearing detecting cable of the present utility model is simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
Claims (2)
1. anticorrosion charge bearing detecting cable, comprise conductive layer (1), conductor wire core (2) and cable sheath (3), conductive layer (1) forms by copper wire is stranded, the outside of conductive layer (1) is extruded with the conductor wire core (2) that insulating material forms, the intertwist body of conductor wire core (2) or conductor wire core (2) is outside equipped with cable sheath (3), it is characterized in that the outer oil resistance anticorrosion layer (4) that is extruded with of cable sheath (3).
