Outside the orientation illustrating, spatial terminology is intended to the different azimuth in use or operation including device.For example, if in figure
Device is squeezed, be stated as positioned at the element of other elements or feature D score will be located into other elements or feature " on ".Cause
This, exemplary term D score can comprise both upper and lower orientation.Device can otherwise position（Ratate 90 degrees or be located at
Other orientation）, can correspondingly explain used herein of space explanation relatively.
A kind of WMF of this utility model series the wear-resisting charge bearing detecting cable of closed type, its structure as shown in figure 1, cable
Center is cable conductor 1, and cable conductor 1 wrapped up by insulating barrier 2, the outside of insulating barrier 2 be followed successively by the screen layer 3 of proof copper-wire braided,
Outer glue-line 4, sleeve pipe 5, inner sheath 6, inner armor layer 7, filling 8, armoured layer 9 and oversheath 10.
Inner armor layer 7 is that many round steel wires are stranded to be formed.Armoured layer 9 is twisted into single-strand rope by soft steel wire, many
Root steel wire rope armouring forms, and because armoured layer 9 is formed by many steel wire ropes are stranded, and every steel wire rope is all by many jewelry, expensive clothing and other valuables
Steel wire is stranded to be formed, and greatly improves pliability, and maintains tensile strength.As the presently preferred embodiments, armoured layer 9 is every
Root steel wire rope all by a core wire and closely surrounds the tight prunus mume (sieb.) sieb.et zucc. that the six roots of sensation peripheral steel wire outside core wire is formed
Flower-shape cross section, described seven steel wire diameter are identical.This kind of scheme has structure simply, effect is significant, cost and technological requirement
Will not be too high.
In addition, also has the steel wire rope scheme that other can substitute, every steel wire rope of such as armoured layer 9 is all by one
Root core wire and some piece peripheral steel wire different from core wire diameter closely surrounding outside core wire are constituted, can
So that core wire and the diameter of peripheral steel wire and the quantity of required peripheral steel wire are determined according to flexibility demand.Anti- in order to improve
Tensile strength, the diameter that the diameter of core wire can be set to more than peripheral steel wire, so closely quincunx in order to surround into
Shape, need increase peripheral steel wire quantity, such as 9 or 10.
Can also there is reduction procedure, such as, soft steel wire is stranded becomes steel wire rope, Neng Goujin only with 3 of same diameter
One step Simplified flowsheet and reduces cost, are simultaneously achieved flexibility requirements.
As other optional forms it is also possible to armoured layer 9 is by the way of steel wire rope and round steel wire are arranged alternately.
Additionally, cable jacket 10 is made using macromolecule polymer material, cable inner wire is protected not corroded, outward
The outer surface of sheath 10 is pure circle type, by the steel wire rope of armoured layer 9 embed oversheath macromolecule polymeric material internal so that electricity
Cable oversheath 10 is combined together with armoured layer 9.
Many steel wire ropes in embedded oversheath 10 be in uniform intervals be distributed, between adjacent two steel wire ropes or steel wire rope with
Spaced distance between round steel wire, the quantity according to intensity and flexibility requirements adjustment steel wire rope and spacing distance are according to intensity
Adjust quantity and the spacing distance of steel wire rope and round steel wire with flexibility requirements respectively.
In order to improve suppleness further, inner armor layer 7 equally can also carry out armouring using steel wire rope.
So that armor is become soft, have powerful stretching resistance using the lay configuration of above-mentioned armor, be obtained in that
There is the flexible cable of minimum bending radius, improve bending resistance, greatly reduce the destructive power to inner lead for the armor, protection
Cable core, finally extends the service life of whole cable and obtains good using effect, have for underground work and greatly change
Kind.
During due to detecting operation, down-hole high pressure liquid often overflows outside well along cable gap, pollutes environment, therefore well
Seal approach extremely important, this utility model has been also carried out a large amount of improvement in seal approach.In inner armor layer 7 and inner sheath
Filling with sealant between 6, filling with sealant between the adjacent wires of inner armor layer 7, between inner armor layer 7 and armoured layer 9
Filling with sealant or extrusion sheath, it is ensured that seamless presence between cable inner armor layer 7 and armoured layer 9, prevent inside cable
Wire is corroded and pollutes；And the gap filling between cable and choke tube has fluid sealant or extrusion sheath it is ensured that going deep into
To during underground work, seamless presence between cable and choke tube, prevent underground high-pressure fluid para-electric cable gap overflow to well face.
Because, between steel wire and steel wire, the gap filling between inner armor layer 7 and armoured layer 9 and between cable and choke tube has close
Sealing or extrusion sheath, cable degree-of-difficulty factor of going into the well reduces, and service life improves, and environmental pollution substantially reduces.
Cable conductor 1, according to different needs, is chosen as single, two cores, three cores, four cores or seven cored structures.
The cable that the present embodiment is provided, using proof copper-wire braided layer as screen layer 3 it is ensured that wired signal transmission pure
Only.The shielding mode of cable, replaces semiconductive material by metallic shield, and shield effectiveness is more thorough, and signal transmission is more stable.
Armoured layer 9 changes into multistrand rope by many round wires, makes cable flexibility and tensile strength obtain pole
The earth improves.
Cable jacket 10 is made using high flexibility macromolecule polymer material, preferred polyamide, the design of oversheath 10
Effectively control the outside diameter of cable, use of conveniently going into the well, reduce the occurrence of meet card, protect cable inner wire not to be subject to corruption simultaneously
Erosion, cable service life is greatly improved.Oversheath 10 outer surface be almost considered as pure circle type, carry to a great extent
High fluency of going into the well.
Although only giving the accompanying drawing of single structure in this programme, but not changing other structures, only changing cable core number
The deformation of other schemes of amount is it should be also considered as falling into the protection domain of this programme.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or new using this practicality
Type.Multiple modifications to these embodiments will be apparent from for those skilled in the art, is determined herein
The General Principle of justice can be realized in the case of without departing from spirit or scope of the present utility model in other embodiments.Cause
This, this utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
