Description
Technical field
The utility model is related to petroleum well logging technology field, and in particular to it is anti-outer crowded that one kind is applied to complex structural well damping
Gauze fabric logging cable.
Background technology
With the quickening of oil gas energy exploration development rate, oil gas well drilling operation is constantly sent out to deeper more complicated stratum
Exhibition, the complicated high formation temperature of casing programme and geothermal well causes traditional armoured logging cable to be difficult to meet high temperature complexity knot
Cable transmission signal capabilities weaken under the well logging use requirement of structure well, high temperature.In complex structural well, traditional armored cable exists
The lower wireline logging process Chang Huiyu boreholes wall collide, and cause signal attenuation, distortion, strata pressure is extremely high or well unstability is caused
Cable bears to squeeze power outside height, and rock of borehole peels off chip off-falling and hits cable, damages sheath, and the cable core layer for losing sheath protection is directly sudden and violent
It is exposed in drilling fluid, insulating barrier has failure risk at any time, causes dropout, well logging failure substantially reduces the true of well logging information
Real reliability, increases well logging cost.
Analyzed based on more than, a kind of anti-outer crowded metal of complex structural well damping that is applied to of the utility model Patent design is knitted
Net logging cable, it is intended to solve the shortcoming that above-mentioned traditional armoured logging cable is present, the damping to improve logging cable is anti-outer crowded
Ability, it is ensured that complex structural well formation information efficiently can be transferred to ground by logging cable.
Utility model content
It is a kind of anti-outer crowded suitable for complex structural well damping that the utility model purpose is that the well logging for miscellaneous structure well is provided
Gauze fabric logging cable, to improve logging signal accuracy, improves cable life.
In order to achieve the above object, the utility model is adopted the following technical scheme that:
One kind is applied to complex structural well damping and resists outer crowded gauze fabric logging cable is main to be filled by external armor layer, gauze fabric
Note rubber layer, lapping layer, filler, cable core insulating barrier, conductive cable core, fine cream, optic fibre core composition.
The conductive cable core and a major diameter that cable has eight minor diameter transmission electric signals transmit the big straight of well logging information
Footpath optic fibre core, large-diameter fibre-optical cable core is conducive to logging signal accurate and quick transmission.
The utility model logging cable designs the rubber layer for being embedded with steel wire knitmesh, and such a design can largely reduce survey
Well cable weight, so as to reduce the pulling force that deadweight is produced, network structure can provide larger tensile strength, and enhancing cable is tough
Property, support is provided cable, and when suddenly by rubbing, torsion, the network structure of gauze fabric can be pind down mutually, be slowed down very
To the deformation for offsetting drastically rubbing, torsion is caused.
Knitmesh gap irrigates organic silicon rubber, and extends to outside gauze fabric.Such a rubber heat resistance can reach 180
DEG C, greatly improve operating temperature of the logging cable in underground interval, it is ensured that logging cable efficient work in the high temperature wells such as geothermal well
Make.It is upper put put logging tool during, because wellbore conditions are complicated, when cable collides with the borehole wall, rubber can lead to
The energy that elastic deformation absorbs collision is crossed, the transmission of vibration wave direction cable core, the attenuation that reduction vibrations are transmitted to signal is reduced.
When by big hole curvature well section, rubber deformation can reduce cable bend generation stress concentration, prevent the triumphant layer of cable because
Stress concentration wrecks.Rubber plays the role of insulation, acid and alkali-resistance simultaneously.The rubber being poured between gauze fabric can knit metal
Net is locked in relevant position, and limitation knitmesh deformation is greatly reduced cable local torsion and deforms and maintain cable balance.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model;
Label in figure:1 external armor layer, 2 gauze fabric castable rubber layers, 3 lapping layers, 4 fillers, 5 cable core insulating barriers, 6 are led
Cable core, 7 fine cream, 8 optic fibre cores
Embodiment
Below in conjunction with accompanying drawing 1, the utility model is described in detail, it is as follows:
It is main by 1 external armor layer, 2 gauze fabrics that one kind is applied to the anti-outer crowded gauze fabric logging cable of complex structural well damping
Castable rubber layer, 3 lapping layers, 4 fillers, 5 cable core insulating barriers, 6 conductive cable cores, 7 fine cream, 8 optic fibre cores.
External armor layer 1 is entwined in certain direction, plays main load-bearing effect.Gauze fabric castable rubber layer 2 is wrapped in cable
Outside core, gauze fabric uses anti-fork braiding to improve load intensity, and enough supports are provided for cable core, are poured in knitmesh
Rubber uses organic silicon rubber, and basic structural unit is made up of silicon-oxygen chain link, and side chain is then various with other by silicon atom
Organic group is connected.The characteristics of rubber tool high temperature resistant, electric insulation, antiacid alkali aging, heat resistance can reach 180 DEG C, good
Good insulating properties can protect cable core normal work, while excellent waterproof acid and alkali-resistance characteristic ensure that cable in pit shaft
Middle normal work.Lapping layer 3 uses insulation effect under polyimides, high temperature well, to play further shielding external environment effect.
Cable core insulating barrier 5 uses polytetrafluoroethylene (PTFE), plays insulating effect.Large-diameter fibre-optical cable core 8 has the spy of quick transmission formation information
Point, fine cream 6, the composition material of optic fibre core 7 are not limited.
