It is required that thousands of rice, partial cables will be overhang in well in well.It is wear-resisting, one can be born therefore it is required that the outside diameter of cable is small and uniform
Determine impact force, to bear to conduct oneself with dignity, to bear oil, the pressure of mud, and be no more than 0.2% in its elongation after by pulling force.It passes
Three core deep-well perforation cables of system, due to using double wire armor, outside diameter of cable size is larger, and cable weight is heavier, this
It requires producer's Gonna breakthrough technical barrier, seeks to break through in terms of the construction of cable or cable new material and new process.
Utility model content
The defects of to overcome the prior art, the purpose of this utility model is to provide a kind of new three cores deep-well perforation electricity
Cable, have it is excellent bear, the characteristics such as outer diameter is smaller, relative weight is relatively light, tolerance mud pressure, can be widely applied to oil well
The fields such as probing, excellent product performance.
The utility model solves technical problem and adopts the following technical scheme that：
A kind of new three cores deep-well perforation cable, including insulated wire cores, the insulated wire cores include conductor and are extruded in lead
External polypropylene insulation layer, several described insulated wire cores are twisted into cable core, and the cable core gap is equipped with cotton yarn filling layer, institute
It states cable core and is coated with interior cloth-one-side sheet band, be woven with outside the interior cloth-one-side sheet band and spin synthetic fibre yarn enhancement layer, the spinning synthetic fibre yarn adds
Outer cloth-one-side sheet band is surrounded with outside strong layer, armor is wound with outside the outer cloth-one-side sheet band.
Further, the conductor is formed using multiply tin annealed copper wire bundle strand, what center was twisted added with three
Spin synthetic fibre yarn.
Further, the pitch multiples of the insulated wire cores stranding are no more than 8 times of conductor assembly outer diameter.
Further, the interior cloth-one-side sheet band and Duplication is not less than 25% during wrapped outer cloth-one-side sheet band.
Further, the spinning synthetic fibre yarn braiding enhancement layer count is not less than 90%.
Further, the armor is zinc-coated wire.
Compared with the prior art, the beneficial effects of the utility model are embodied in：
The utility model have it is excellent bear, the characteristics such as outer diameter is smaller, relative weight is relatively light, tolerance mud pressure, can
To be widely used in the fields such as oil well probing, excellent product performance.
1st, added in conductor and spin the tensile strength that synthetic fibre yarn enhances conductor；
2nd, cable is changed and is replaced by steel wire of internal layer by the spinning synthetic fibre yarn woven, due to being spun synthetic fibre yarn by two layers of traditional wire armoring
Tensile strength be more than steel wire tensile strength, bear ability which enhances cable；
3rd, cable is changed and is replaced by steel wire of internal layer by the spinning synthetic fibre yarn woven, reduced cable by two layers of traditional wire armoring
Outer diameter.

Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
As shown in Figure 1, a kind of new three cores deep-well perforation cable, including insulated wire cores, insulated wire cores include conductor 1 and squeeze
Wrap the polypropylene insulation layer 2 outside conductor 1；Several insulated wire cores are twisted into cable core, and cable core gap is equipped with cotton yarn filling layer 3,
To ensure cable roundness；Cable core is coated with interior cloth-one-side sheet band 4, is woven with outside interior cloth-one-side sheet band 4 and spins synthetic fibre yarn enhancement layer
5, it spins and outer cloth-one-side sheet band 6 is surrounded with outside synthetic fibre yarn enhancement layer 5, armor 7 is wound with outside outer cloth-one-side sheet band 6.
In specific implementation, corresponding structure setting and material selection are respectively：
Conductor 1 is formed by multiply tin annealed copper wire bundle strand, center added with synthetic fibre yarn is spun, spin synthetic fibre yarn it is twisted by three and
Into, it is desirable that tension is uniform when the copper wire of bundle strand is without stranded and bundle strand；
Polypropylene insulating layer 2 is extruded on conductor, it is desirable that average thickness and thickness thinnest point and insulation core shift degree meet work
Skill requirement；
Three insulated wire cores carry out stranding, and the requirement filling of cotton yarn filling layer 3 is close, meets the cable core roundness after stranding
