Abstract
The invention provides a lock strand sealing type loaded exploration detection cable. An insulation layer is arranged outside conductors in the center. An inner steel wire layer is arranged outside the insulation layer. An outer steel wire layer is arranged outside the inner steel wire layer. The steel wires of the outer steel wire layer are lock strand structures in pair overlapping, the inner surfaces of the steel wires of the outer steel wire layer are straight surfaces or arc surfaces, and the outer surfaces are irregular steel wires with Z-shaped or S-shaped arc surfaces. According to the lock strand sealing type loaded exploration detection cable, the contact surface in the use process is large, the wear resistance is good, and the service life is long, the outer layer is a lock strand structure, the entry of oil, gas and water is blocked, a sealing effect is achieved, the stretching rate of the whole cable is reduced, twisted phenomena in the use process are reduced, a complete circle is formed by the inner layer steel wires to fully protect a cable core, the irregular steel wires are employed by the inner and outer layers such that the cable elasticity is reduced, in oil well or mine well detection, the cable is more suitable for uneven and curved downhole environments, the possibility of deformation and looseness is little, and the possibility of steel wire fracture in bending is little.
Description
Technical field
The present invention relates in transmission signal cable field, especially a kind of DH exploration cable.
Background technology
The depth location that the important function of DH exploration cable is exactly the various downhole probe of conveying, transmit various signals between ground control system and downhole instrument, obtain down-hole information.Detect the construction of cable under conventional well as shown in Figure 1, insulated core 3 outside being positioned at center is provided with steel wire floor 2 and the two-layer steel wire of outer steel wire floor 1, cable outer layer forming curves circle structure, and anti-disconnected power is low, and internal stress is unbalanced; Round steel wire easy injured fracture and jump silk when bending in addition, simultaneously, in oil well and mine in dynamic use procedure, cable is easily out of shape by during blowout preventer, thus cause cover wire loose, wear no resistance, for these reasons, easily there is the generation causing underground work accident because of cable fault in the well of complexity and in super large inclined shaft.
Summary of the invention
In order to overcome traditional DH exploration cable above shortcomings and defect, the invention provides a kind of lock stock formula closed type charge bearing detecting cable.
The technical scheme that the present invention is adopted for achieving the above object is: lock stock formula closed type charge bearing detecting cable, conductor 7 outside being positioned at center is provided with insulating barrier 6, insulating barrier 6 outside is provided with interior steel wire floor 5, interior steel wire floor 5 outside is provided with outer steel wire floor 4, and the steel wire of outer steel wire floor 4 is the lock stock formula structure overlapped between two.
To be inner surface be the steel wire of described outer steel wire floor 4 faces directly or cambered surface, outer surface are the deformed wire of the Z-shaped or class S shape of the class of cambered surface.
Described interior steel wire floor 5 to be class scallop wire, inner surface and outer surface be cambered surface or the class faced directly is Z-shaped or the steel wire of class S shape, inner surface be face the class trapezoidal wire that upper surface is cambered surface directly, staggered bottom surface is to face directly or the class triangular wire of cambered surface, inner surface and upper surface are cambered surface or the class diamond wire faced directly or round wire.
Described outer steel wire floor 4 and interior steel wire floor 5 material are the high carbon materials or the stainless steel material that are greater than more than 65 manganese grades.
Lock stock formula closed type charge bearing detecting cable of the present invention, because outer steel wire floor and steel wire of internal layer adopt deformed wire structure, steel product cross-sectional is long-pending large, and cable pull-off force is higher than traditional cable; Cable cylindrical is close to straight line circle, and in use procedure, contact-making surface is large, resistance to wear good, improves and uses cable useful life; Skin is Z-shaped or S shape deformed wire, adopts lock stock formula structure, stops entering of oil, vapour and water, play sealing function; Cover wire lock stock formula structure makes cover wire there will not be and jumps silk and lantern phenomenon; The lock stock formula structure of cover wire and ectonexine adopt deformed wire that whole piece cable expansion rate is reduced; Ectonexine steel wire difformity is combined, and makes to reduce from turn-week number, makes to beat in use procedure and turns round phenomenon minimizing; Steel wire of internal layer forms a complete circle, plays sufficient protective effect to cable core, the capacitance of cable and insulating properties is played a protective role, makes its stable performance; Ectonexine all adopts deformed wire, and cable elasticity is diminished, and when oil well or Mine pit survey, is more suitable for uneven, the bending not straight operating environment in down-hole; In oil well, the dynamic use procedure of mine, be not easy distortion and loose, be not easy time bending rupture.
