Abstract
A special steel pipe cable comprises an insulation cable core positioned in the center. An inner steel wire and an outer steel wire are arranged outside the insulation cable core, and a steel pipe is mounted between the inner steel wire and the outer steel wire. According to the invention, when the steel pipe cable is used, the steel wires can be prevented from being twisted even if the cable is blocked, so that the damage of the outer steel wire of the cable is avoided, and the service life of the cable is prolonged. In addition, the structure improves the overall elasticity of the cable, and increases the anti-abrasive strength of the cable in the work of physical geography, so as to prolong the service life of the cable and ensure that the cable can successfully complete the related tests of horizontal wells and slant wells in oil well logging.
Description
Technical field
The present invention relates in field of telecommunications cables exploration cable under especially a kind of oil well.
Background technology
The important function of 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 under the oil well.It is as shown in Figure 1 to survey the construction of cable under the conventional well, and insulation cable core 3 outsides are provided with steel wire of internal layer 2 and cover wire 1, and contact is installed between the steel wire floor; In use, when cable is hampered, will produce " beat and turn round " phenomenon; Cause the cable outer layer steel wire badly damaged, thereby shortened the useful life of cable; And insulating material quality 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 under the conventional well exists, the invention provides that a kind of steel wire floor is not fragile, the steel pipe cable of long service life.
The present invention for realizing the technical scheme that above-mentioned purpose adopted is: the Steel Tube Special cable, comprise the insulation cable core that is positioned at the center, and insulation cable core outside is provided with steel wire of internal layer and cover wire, between cover wire and the steel wire of internal layer steel pipe is installed.
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 installed steel pipe between steel wire of internal layer and the cover wire, during use; Cable is when being hampered, and steel wire can not produce " beat and turn round " phenomenon, thereby has avoided the damage of cable outer layer steel wire; Prolonged the useful life of cable, and this structure increases the overall elasticity of cable, increased the abrasion strength resistance of cable in geophysics work; And then the useful life of having improved cable, make it to accomplish smoothly the dependence test of horizontal well in the oil well logging, inclined shaft.
Description of drawings
Fig. 1 is the structure chart of traditional cable.
Fig. 2 is the structure chart of Steel Tube Special cable of the present invention.
Embodiment
The steel pipe construction of cable of the present invention is as shown in Figure 2; Comprise the insulation cable core 3 that is positioned at the center; Insulation cable core 3 outsides are provided with steel wire of internal layer 2 and cover wire 1; Steel pipe 4 is installed between cover wire 1 and the steel wire of internal layer 2, and 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.
Hesitate between traditional cable steel wire floor and the steel wire floor steel pipe is not installed, in use, when cable is hampered, will produce " beat and turn round " phenomenon, cause the badly damaged of cable outer layer steel wire 1, thereby cause the life-span of cable to descend rapidly.Steel pipe 4 is installed between steel pipe cable steel wire of internal layer 2 of the present invention and the cover wire 1, and during use, cable is when being hampered; Steel wire can not produce " beat and turn round " phenomenon, thereby has avoided the damage of cable outer layer steel wire 1, has prolonged the useful life of cable; And this structure has increased the overall elasticity of cable; Increase the abrasion strength resistance of cable in geophysics work, and then the useful life of having improved cable, made it to accomplish smoothly the dependence test of horizontal well in the oil well logging, inclined shaft.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.
