Abstract

The utility model discloses an optic fibre well logging bearing load exploration cable for system, the cover has nonrust steel pipe outside optical fiber unit, the semicircular groove of indent all is equipped with in the centre on six limits of regular hexagon rubber skeleton, put 6 conductive core respectively in six semicircular groove, put the inside center department at regular hexagon rubber skeleton with optical fiber unit, be connected with the rubber strengthening rib between the nonrust steel pipe in the optical fiber unit outside and six interior angles of regular hexagon rubber skeleton respectively, at the aramid fiber yarn filling layer that blocks water of the outside of regular hexagon rubber skeleton cladding in proper order, glass fiber tape adds pottery vitrification silicon rubber area around the covering, aluminium strip lock armo layer, rope winding layer is torn to the polyester material, carbon fiber wire weaving layer and oversheath. The utility model discloses having increased regular hexagon rubber skeleton, having increased the intensity of cable, established nonrust steel pipe at the center of rubber skeleton, and be connected with the rubber strengthening rib, the memory of the nonrust steel pipe of increase is returned and is contracted, increases life.

Description

A kind of optical fiber logging system charge bearing detecting cable

Technical field

This utility model relates to field of cable technology, particularly relates to a kind of optical fiber logging system charge bearing detecting cable.

Background technology

Optical fiber logging system charge bearing detecting cable, compared with traditional charge bearing detecting cable, has transfer rate high, frequently The advantage such as bandwidth, anti-electromagnetic-radiation, therefore suffers from the attention of domestic and international Ge great Logging Company.Be widely used in physical prospecting, well logging and Oil recovery field tests.

Utility model content

This utility model purpose is contemplated to make up the defect of prior art, it is provided that a kind of optical fiber logging system is visited with holding lotus Survey cable.

This utility model is achieved through the following technical solutions:

A kind of optical fiber logging system charge bearing detecting cable, includes 6 conductor wire cores, 1 fiber unit and positive six Limit shape rubber skeleton, described conductor wire core is constituted by being surrounded by fluoroplastic insulation layer outside copper conductor, outside fiber unit Side is cased with stainless steel tube, is equipped with the semi-circular recesses of indent in the centre on six limits of regular hexagon rubber skeleton, leads 6 Wire core is individually placed in six semi-circular recesses, is placed on by fiber unit at the inside center of regular hexagon rubber skeleton, light It is connected to rubber reinforcement, just between stainless steel tube and six interior angles of regular hexagon rubber skeleton outside fine unit It is wrapped that the outside of hexagon rubber skeleton is coated with water resistance aramid fiber yarn packed layer successively, glass fiber tape adds Ceramic silicon rubber band Layer, aluminium strip lock armo layer, polyester material tear rope winding layer, carbon fiber wire braid and oversheath.

1, cable conductor arrangement

Cable core is made up of 6 conductor wire cores and one group of fiber unit, and its arrangement architecture is by two kinds, and one is fiber unit part Middle, two is that fiber unit part is divided in outside.No matter how how fiber section arranges, below we will sufficiently consider 2 factors: 1, the extension of the stainless steel tube of outside of fiber, because cable meeting when cable in use, runs into carrying pulling force Elongation, will not remember retraction, be easily caused outer stainless steel tube and draw thinner and thinner, affect the longevity of cable after stainless steel tube tensile elongation Life.2, the flexibility of stainless steel tube, it is the most curved that the normal pulley motion excessively of cable makes the stainless steel tube outside optical fiber be chronically at Curved state, its flexural fatigue diameter also directly influences the life-span of cable.

2, insulant

The insulant of cable is considered as using ETFE, the advantage of this fluoroplastics maximum to be that resistance to mechanical pressure is big, be difficult to Cracking, compared with modified polypropene PP, fluoroplastics FEP, electrically and physically performance is still essentially different.

The utility model has the advantages that: this utility model adds regular hexagon rubber skeleton, add the intensity of cable, Stainless steel tube is located at the center of rubber skeleton, and connection has rubber reinforcement, the memory retraction of the stainless steel tube of increase, increase In service life, insulation shielding is effective.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

As it is shown in figure 1, a kind of optical fiber logging system charge bearing detecting cable, include 6 conductor wire cores, 1 optical fiber list Unit 1 and regular hexagon rubber skeleton 2, described conductor wire core is to constitute by being surrounded by fluoroplastic insulation layer 4 outside copper conductor 3 , outside fiber unit 1, it is cased with stainless steel tube 5, is equipped with indent in the centre on six limits of regular hexagon rubber skeleton 2 6 conductor wire cores are individually placed in six semi-circular recesses, fiber unit 1 are placed on regular hexagon rubber by semi-circular recesses At the inside center of skeleton 2, divide between stainless steel tube 5 and six interior angles of regular hexagon rubber skeleton 2 outside fiber unit 1 Lian Jie there is not rubber reinforcement 6, be coated with water resistance aramid fiber yarn packed layer 7, glass successively in the outside of regular hexagon rubber skeleton 2 Fiber band adds Ceramic silicon rubber band lapping layer 8, aluminium strip lock armo layer 9, polyester material tear rope winding layer 10, carbon fiber wire Braid 11 and oversheath 12.

Claims

1. an optical fiber logging system charge bearing detecting cable, it is characterised in that: include 6 conductor wire cores, 1 fiber unit And regular hexagon rubber skeleton, described conductor wire core is constituted by being surrounded by fluoroplastic insulation layer outside copper conductor, at light Being cased with stainless steel tube outside fine unit, the semicircle being equipped with indent in the centre on six limits of regular hexagon rubber skeleton is recessed 6 conductor wire cores are individually placed in six semi-circular recesses, fiber unit are placed on the inside of regular hexagon rubber skeleton by groove Center, is connected to rubber between stainless steel tube and six interior angles of regular hexagon rubber skeleton outside fiber unit and adds Strong muscle, is coated with water resistance aramid fiber yarn packed layer successively in the outside of regular hexagon rubber skeleton, glass fiber tape adds pottery SiClx Rubber strip lapping layer, aluminium strip lock armo layer, polyester material tear rope winding layer, carbon fiber wire braid and oversheath.
