Abstract
A steel pipe type cable comprises a central insulating cable core, inner steel wires and outer steel wires. The inner steel wires and the outer steel wires are arranged outside the insulating cable core, a steel pipe is arranged outside the outer steel wires, the insulating cable core comprises a conductive cable core and an insulating layer, and the conductive cable core is a copper wire. By means of the steel pipe arranged outside the outer steel wires, nonresistance to wear of traditional steel wire armoring is changed, and wear resistance degree of the cable in geophysical operation can be increased, so that the service life of the cable is prolonged. The cable is applicable to smooth oil logging in horizontal wells, deviated wells and 'S-shaped' wells. During use, well mouth sealing factor can be increased, so that non-leakage of underground hydrostatic pressure, oil, gas, water and the like is achieved, and related requirements on environmental protection are realized.
Description
Technical field
The present invention relates in field of telecommunications cables especially a kind of down-hole exploration cable.
Background technology
The important function of down-hole exploration cable is exactly to carry various downhole probes, transmit various signals between ground control system and the downhole instrument, obtain the depth location of down-hole information.It is as shown in Figure 1 to survey the construction of cable under the conventional well; Insulation cable core 3 outsides are provided with steel wire of internal layer 2 and cover wire 1, traditional cable in use because the base attribute of armouring wire is cylindrical; In the borehole wall wearing and tearing point and the wearing and tearing of line, promptly and the life-span of cable sharply shortens.And the intensity of armouring wire and antiseptic power are relatively poor or steel wire in the middle of have reason such as joint also to cause outer armour fracture of wire easily; Insulating material quality problems or heat resistance are relatively poor, cause insulating barrier aging very fast, and the cable core insulating capacity descends.
Summary of the invention
In order to overcome above-mentioned deficiency and the defective that exploration cable exists under the conventional well, the invention provides a kind of anti abrasive steel pipe cable.
The present invention for realizing the technical scheme that above-mentioned purpose adopted is: the steel pipe cable, comprise that the insulation cable core, the insulation cable core outside that are positioned at the center are provided with steel wire of internal layer and cover wire, and the cover wire outside is provided with steel pipe.
Said insulation cable core comprises conduction cable core and insulating barrier, and the conduction cable core is a copper wire.
Steel pipe cable of the present invention is provided with steel pipe in the cover wire outside, has changed tradition with the not anti abrasive way of wire armoring, can increase the wear-resistant degree of cable in geophysics work, improves the useful life of cable with this; This cable is applicable to horizontal well in oil well logging, the trouble-free operation of operation in inclined shaft and " snakelike " well; In use, can also improve the well head gasket factor, thereby down-hole fluid pressure and oil, gas, water etc. are not leaked, to reach the related request of environmental protection.
Description of drawings
Fig. 1 is the structure chart of traditional cable.
Fig. 2 is the structure chart of steel pipe cable of the present invention.
Embodiment
The steel pipe construction of cable of the present invention is as shown in Figure 2, comprises that the insulation cable core 3, insulation cable core 3 outsides that are positioned at the center are provided with steel wire of internal layer 2 and cover wire 1, and cover wire 1 outside is provided with steel pipe 4.Armour divides steel wire of internal layer 2 and cover wire 1, the armouring wire internal layer be dextrorotation around, skin be left-handed around, this mode can strengthen the anti-twisting property of cable.Insulation cable core 3 comprises conduction cable core and insulating barrier, and the conduction cable core adopts the coiling of high-quality copper wire to form.
Traditional cable because the base attribute of armouring wire is cylindrical, is point in borehole wall wearing and tearing and the wearing and tearing of line in use, promptly and the life-span of cable sharply shortens.Steel pipe cable of the present invention is provided with steel pipe in the cover wire outside, has changed tradition with the not anti abrasive way of wire armoring, can increase the wear-resistant degree of cable in geophysics work, improves the useful life of cable with this; Traditional insulating material quality problems or heat resistance are relatively poor; Cause insulating barrier aging very fast; The cable core insulating capacity descends; The insulating barrier of cable of the present invention adopts the fluoroplastics, polypropylene of electric property and better mechanical property, too material such as fluon is processed, and has the characteristic of oil resistant air water and soda acid salt corrosion, increases the service life greatly.And this cable is applicable to horizontal well in oil well logging, the trouble-free operation of operation in inclined shaft and " snakelike " well; In use, can also improve the well head gasket factor, thereby down-hole fluid pressure and oil, gas, water etc. are not leaked, to reach the related request of environmental protection.
