Description
Technical field
The utility model relates to a kind of exploration cable, is specifically related to a kind of charge bearing detecting cable.
Background technology
Charge bearing detecting cable mainly refers to bear under mechanical load (sash weight the adds the cable deadweight) situation, carries out the double wire armor cable that the down-hole oil field is surveyed, and claims the oil well logging cable again, and its function has well logging, perforation, gets core etc.Mostly logging cable is 7 cores, and requires it to have length and high-intensity characteristic.
Logging cable is called as " oil worker's eyes " in petroleum industry.Just can know underground through it is oil or gas, and can measure technical parameters such as well temperature, well pressure and hole deviation.
The structure of the steel wire armored cable that logging cable is commonly used is as shown in Figure 1, generally comprises and leads conductive copper wire core 1, fluoroplastics F46 insulating barrier 2, semiconductive phase-splitting screen 3, filler 4, semiconductive nylon tape 5 and zinc-coated wire armour 6.
The lower end of logging cable is an electrode cable; Be commonly called as the head harness cable, be used to hang testing meter and instrument, the about 270kg of weight; Add the about 560～580kg/km of the weight of cable own; After cable is gone into the well, need bear very big pulling force, add in the stratum pressure of itself, and need bear that temperature in the well raises and the erosion, particularly H of oil gas
2The erosion of S.Under above-mentioned this environment for use, following problem often appears in existing charge bearing detecting cable in practical application:
1. the wire armoring layer has in process of production together that very important operation is exactly the pre-stretching operation; Behind wire armoring, need through pre-stretching equipment; Its objective is the prestressing force of eliminating two steel wires; But still can some residual residue stresses exist in actual use, thereby steel wire will loose flower and makes strain relief clamp well, serious meeting cause the fracture of cover wire and produce card well phenomenon in the down-hole.
In the well except mud, oil gas are arranged, also have hydrogen sulfide (H
2S), it is very serious to the corrosion of steel wire, and general high-tensile steel wires are hydrogen sulfide corrosion-resistant not.These corrosion damages possibly cause cable to scrap, even cause a bite well to scrap.
3. the charge bearing detecting cable invar silk and the friction between the borehole wall that have the wire armoring layer make steel wire become flat filament by initial round steel monofilament, thereby make its one side that contacts with the borehole wall become the plane.Using its steel wire of back to deform repeatedly, pulling force diminishes, and causes cable to scrap.
4. because cable needs work under very abominable high temperature, hyperbar and corrosive environment, the life-span that generally has the cable of wire armoring layer can not surpass 300 wells yet.
In addition, because logging cable belongs to fixed length production, link goes wrong, and a then whole cable is supporting not to be become or scraps; Loss is huge; Therefore, the charge bearing detecting cable with wire armoring layer is very harsh to its technological requirement in production process, and this has also increased the cost of manufacture of cable virtually.And because down-hole pressure is big and increase rapidly, the tensile strength of the steel wire of therefore armouring being used requires than higher, and should select tensile strength for ultradeep well is the steel wire of 2000MPa, and the tensile strength of high-tensile steel wires (GB1178) is 1400MPa (140kg/mm at present
2), can't reach the tension requirement of ultradeep well.
The utility model content
The utility model technical problem to be solved makes the above-mentioned shortcoming that exists to the prior art logging cable, and providing a kind of can work under high temperature, hyperbaric environment, and is corrosion-resistant and can significantly improve the charge bearing detecting cable of tensile strength.
The technical scheme that solution the utility model technical problem is adopted is that this charge bearing detecting cable includes insulated wire cores, lapping layer and armour from inside to outside successively; Wherein, Said armour includes bilayer or multilayer carbon fiber wire layer, twists together formation through said bilayer or multilayer carbon fiber wire helical layer.
Wherein, the spiral direction of lay between said any two-layer carbon fiber wire layer is a reverse stranding.
Preferably; Said carbon fiber wire layer comprises cementing layer and glass fiber layer; Said glass fiber layer is coated on outside the said cementing layer; Said cementing layer comprises carbon fiber filament and thermosetting modification epoxy resin, carbon fiber filament that said bundle closes and the said cementing layer of thermosetting modification epoxy resin formation glued together.
Preferably, the armouring pitch of formed armour is than 6.5 times～8.5 times for said charge bearing detecting cable diameter.
Preferred described insulated wire cores comprises the insulating barrier that conductor is outside with being coated on conductor.
Preferably, described insulating barrier by polypropylene, thermostable fluorine mould, modified polypropylene material, ethylene-tetrafluoroethylene copolymeric material, perfluoroethylene-propylene or tetrafluoroethene-perfluoroalkyl vinyl ether process.
Further preferably, described insulating barrier outside also is coated with semiconductive phase-splitting screen.
Wherein, the core number of described insulated wire cores is 1,3,4,5 or 7 cores.
Wrapped the processing of twining package tape that preferred described lapping layer adopts wrapped or employing of semi-conductive tape and conductor temperature grade to adapt.
The beneficial effect of the utility model charge bearing detecting cable is following:
1. include the carbon fiber wire layer owing in the armour, and the tensile strength of carbon fiber wire is 3.5 times of steel wire, the pulling force that it bore is big, thereby this charge bearing detecting cable can not produce fracture card well phenomenon.
2. because the thermal coefficient of expansion of said carbon fiber wire layer is a negative value; And absolute value is the last 1/10 of steel wire; This charge bearing detecting cable is under the high temperature of down-hole, high hydraulic pressure and anticyclonic environment; The thermal deformation that its carbon fiber wire produced is contraction distortion, and shrinks minimumly, has effectively avoided loose in the down-hole phenomenon of flower Ka Jing of cable.
3. because the carbon fiber wire layer has oil resistant, corrosion resistance characteristic, anti-hydrogen sulfide especially, the useful life of having improved this charge bearing detecting cable cable greatly in the down-hole.
4. because the carbon fiber wire layer has than the better resistance to wear of existing wire armoring layer, do not have the situation of noticeable wear under the situation about using repeatedly in the down-hole yet, thereby this charge bearing detecting cable is prolonged useful life.
5. because the density of carbon fiber wire layer is little, and its density is 1/4 of steel wire density, its diameter is 1/20 of a steel wire, can effectively reduce to have this charge bearing detecting cable own wt, reduces raw-material use, thereby can practice thrift cost.
The access times of the utility model charge bearing detecting cable surpass 800 wells, improve more than 50% service time than existing cable, and be significantly improved useful life.
