Abstract
The utility model relates to a heating cable, in particular to a carbon fiber heating cable special for exploiting heavy oil and high-pour-point oil. The carbon fiber heating cable for oil exploitation has the following structure that: a core of the carbon fiber heating cable for oil exploitation is a framework (1); a carbon fiber heating wire (4) is inlayed on the framework (1); the framework (1) is wrapped with a layer of insulating strip (2); and the insulating strip (2) is wrapped with a layer of steel armor (3). The cable has high efficiency in electricity-heat conversion and can generate more heat under the condition of consuming the same electric energy; the outer steel armor is a whole, so the cable is high in reliability; the cable is light in weight and is half lighter than a copper-core iron-armor cable; and the energy saving effect of the cable is quite obvious.
Description
Technical field
The utility model relates to a kind of heating cable, particularly relates to a kind of viscous crude and the high special-purpose oil recovery carbon fiber heating cable of oil exploitation that coagulates.
Background technology
Viscous crude and high coagulating when oil is exploited must be adopted special-purpose heating cable, so that improve the flowability of crude oil.At present, extensively the heating cable that adopts is a kind of intermediate frequency heating cable, is commonly called as copper core iron armour cable.The SMIS of cable is a copper, and crust is a mail, between copper core and the mail crust insulating barrier is arranged.Copper core iron armour cable is put into hollow rod, with copper core and mail short circuit, make copper core and mail constitute a galvanic circle in the lower end of cable.When heating cable applies voltage of intermediate frequency about frequency 500Hz～1000Hz, voltage 1200V, just can flow through the same frequency electric current in the heating cable.Because skin effect, mail resistance increases, thereby has a resistance heating.Change frequency of supply, can change the resistance of mail, thereby change the caloric value of mail.
Because the restriction of heating principle and cable construction, there is following problem in this intermediate frequency heating: 1, must the assembling high-power medium-frequency transformer.Because the overall electrical resistance of immediate frequency cable is bigger,, need intermediate frequency transformer to provide sufficiently high supply power voltage for immediate frequency cable for necessary load current is provided.Because the operating frequency of transformer is higher, make the loss of transformer increase, thereby reduced the whole heating efficiency of heating cable to a certain extent, also increased equipment volume, weight and cost simultaneously; 2, heating cable is from great, 1000 meters nearly 1.5 tons.In oil recovery process, heating cable is dragged to do by motor with the pump housing and sucker rod and pumps.The deadweight of heating cable is high more, and is also just high more to the power requirement of motor, also increased the electric energy of electrical consumption simultaneously; 3, this cable is by 8 meters one section, and one section one section welds, and insulating properties is bad, and often by voltage breakdown, failure rate is very high in the on-the-spot use.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of heavy crude producing and the high special-purpose oil recovery carbon fiber heating cable of oil that coagulates, and its purpose is: improve the electric conversion efficiency of heating cable, realize energy-conservation target; Simplify the heating cable power supply unit, reduce supply power voltage, improve the reliability of heating cable and control system thereof; And saved supply transformer.
For reaching above-mentioned purpose, the utility model is achieved by the following technical solution:
Recover the oil and use the carbon fiber heating cable, its structure is as follows: its core is a skeleton, is inlaid with carbon fiber heating line on the skeleton, and the outer bread of skeleton is established one deck insulating tape, and the outside bag of insulating tape is established one deck steel armour.
The external diameter of described skeleton is 12-14mm.
Described carbon fiber heating line evenly distributes along the skeleton excircle.
The thickness of described steel armour is 0.8-1.2mm.
Because adopt said structure, make the utility model heating cable have following advantage and effect: 1, supply power voltage is low, power supply does not need output transformer to boost, and has both reduced the energy consumption of transformer, provides cost savings yet.
2, this kind cable is in light weight, has only half of copper core iron armour cable weight, and energy-saving effect is also very remarkable.
3, outer steel armour is an integral body, and the reliability of cable has improved.
4, adopt the utility model cable can improve the electric conversion efficiency of heating cable; Simplify the heating cable power supply unit, reduce supply power voltage, improve the reliability of heating cable and control system thereof; And save supply transformer.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, skeleton; 2, insulating barrier; 3, steel armour; 4, carbon fiber heating line.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, but protection range of the present utility model is not limit by embodiment.
As shown in Figure 1, the utility model recovers the oil and to use the carbon fiber heating cable, and its structure is as follows: its core is the skeleton 1 that heat conduction, insulation, exotic material are made, and external diameter the best of skeleton 1 is 13.5mm; Be inlaid with carbon fiber heating line 4 on the skeleton 1, carbon fiber heating line 4 evenly distributes along the skeleton excircle; Outer bread one deck insulating tape 2 of skeleton 1, insulating tape 2 requires heat conduction and high temperature resistant, and the external diameter the best of having wrapped insulating tape 2 is 14.0mm; Outside bag one deck steel armour 3 of insulating tape 2, thickness the best of steel armour 3 is 1.0mm, the outside diameter of cable the best of having wrapped steel armour 3 is 16.0mm.
Above-mentioned skeleton requires high temperature resistant, and has good insulation performance performance and good heat-conducting.Skeleton not only plays the support fixation effect to carbon fiber, can also make between the carbon fiber simultaneously to insulate.The heat that the skeleton good heat-conducting can make carbon fiber send is evenly distributed in each place of cable inside.Carbon fiber is a heater.Insulating barrier makes carbon fiber and outer steel armour mutually insulated.The effect of steel armour has two, and the one, the carbon fiber of cable inside is shielded, prevent that exterior object from damaging carbon fiber, prevent that also oil, water etc. from entering cable inside simultaneously.Second effect of steel armour is load-bearing.The length of heating cable is between 800m～1500m, and the weight of cable is about 500Kg～1000Kg, and load-bearing relies on the steel armour of cable outer layer fully.The heat conductivility of steel is fine in addition, can apace the heat of cable inside be transmitted to the outside of cable.
