Description
Technical field：
A kind of oil exploitation industry is the utility model is related to, electricity is heated more particularly to a kind of special three core of Rodless oil extraction
Cable.
Background technology：
Paraffin or paraffin deposit thing are present in the crude oil of various ranks.During exploitation, if without additionally heating, then
Oil temperature reduction since when it leaves stratum is continued until that crude oil arrives at oil plant.When temperature is brought down below wax crystal point,
Paraffin is precipitated crude oil, slowly becomes larger after forming crystallization and is deposited on inside oil extraction pipeline or oil well pipe sleeve, handles and separation is set
Inside standby internal, oil-stocking equipment.If oil well has excessive paraffin deposit thing, it is simultaneously final completely plugged that crude oil flow can be limited
Petroleum pipeline.When the small-sized micella containing paraffin such as micro- reversed-phase emulsion are suspended in recovered water, it may occur that through commonly overlooked
Another problem：When these recovered waters containing paraffin are then injected into stratum, contained paraffin can block oil pipe perforation and
Pore throat, or even block stratum.Therefore say, when the deposition of paraffin is serious, it is necessary to which oil well shutdown maintenance, directly influences
Oil recovery efficiency.
Rodless oil extraction uses electric submersible pump, latent oil and directly drives pump, reciprocating pump etc., since the deposition of paraffin needs frequent shutdown to scrape
Wax, construction is complicated and costly, carrys out many inconvenience to layered producing zones, has also affected oil recovery efficiency.
Utility model content：
Technical problem to be solved in the utility model is：Overcome the deficiencies of the prior art and provide a kind of simple in structure, logical
Cross the heat that power Transmission produces in itself to be heated, can prevent oil from blocking the special three cores heating electricity of Rodless oil extraction of oil pipe
Cable.
The technical solution of the utility model is：A kind of special three cores heating cable of Rodless oil extraction, including conductive exothermal core and
Oversheath, the conductive exothermal core is three, and is arranged on into triangle disposition in oversheath, between three conductive exothermal cores
Gap in be provided with steel wire intertwist body, the conductive exothermal core includes aluminium alloy conductor and is closed by the inner aluminium that is successively set on outward
Kapton, F46 on golden conductor layer and polypropylene inner sheath, the steel wire intertwist body are three, and in falling " product " word
Shape is set.
It is described polyimide film sintered on aluminium alloy conductor, and sinter layer is formed, the steel wire intertwist body is twisted
Steel wire.
The aluminium alloy conductor is aluminum alloy material, and the oversheath is polypropylene material, the propylene inner sheath with it is outer
Be provided with sheath work in coordination use it is annular corrugated.
The beneficial effects of the utility model are：
1st, the utility model is provided with the conductive exothermal core and steel wire intertwist body being staggered in triangle disposition, realizes cable
Heating function, while the setting of steel wire intertwist body ensure that the intensity of cable.
2nd, three conductive exothermal cores of the utility model are independently arranged, and are disposed with from inside to outside on conductive exothermal core poly-
Imide membrane, F46 layers and polypropylene inner sheath, realize the protection to conductive exothermal core, realize the effect of insulation.
3rd, three conductive exothermal cores of the utility model and three steel wire intertwist bodies are staggered into triangle disposition, reduce electricity
While cable cross-sectional area, moreover it is possible to added the intensity of cable, extended the service life of cable.
4th, the utility model propylene inner sheath be provided with oversheath work in coordination use it is annular corrugated, have limit
Bit function, by increasing capacitance it is possible to increase the frictional force between oversheath and inner sheath, prevents conductive exothermal core to be connected insecure make with oversheath
Into displacement.
Brief description of the drawings：
Fig. 1 is the structure diagram that special three core of Rodless oil extraction heats cable.
Fig. 2 is the structure diagram that polypropylene inner sheath is connected with oversheath.
Embodiment：
Embodiment：Referring to Fig. 1 and Fig. 2, in figure, 1- aluminium alloy conductors, 2- oversheaths, 3- steel wire intertwist bodies, 4- polyamides is sub-
Amine film, F46 layers of 5-, 6- polypropylene inner sheaths.
The special three cores heating cable of Rodless oil extraction, including conductive exothermal core and oversheath 2, conductive exothermal core are three, and
It is arranged on into triangle disposition in oversheath 2, steel wire intertwist body 3, conduction hair is provided with the gap between three conductive exothermal cores
Hot core includes aluminium alloy conductor 1 and by the inner Kapton 4 being successively set on outward on aluminium alloy conductor 1,5 and of F46 layers
Polypropylene inner sheath 6, steel wire intertwist body 3 are three, and are in the setting of falling triangle disposition.
Kapton 4 is sintered on aluminium alloy conductor 1, and forms sinter layer, and steel wire intertwist body 3 is braided wires,
Steel wire intertwist body 3 is poured with 2 being integrated of oversheath and is molded.
Aluminium alloy conductor 1 is aluminum alloy material, and oversheath 2 is polypropylene material, and propylene inner sheath 6 on oversheath 2 with setting
Be equipped with work in coordination use it is annular corrugated.
In use, one end of aluminium alloy conductor 1 is dived with oil pumps connection, in the other end plus three-phase voltage（Wherein voltage according to
Cable length difference is adjusted）, in galvanization, heat production can be sensed under the action of electric current, and oil is heated,
Prevent oil from occurring condensation in transmitting procedure.
The above descriptions are merely preferred embodiments of the present invention, and not the utility model is made in any form
Limitation, every any simple modification made according to the technical essence of the utility model to above example, equivalent variations with
