Description
Technical field
The utility model relates to the heating tube field, is specially the high-power heating tube of a kind of oil well three-phase overlength.
Background technology
At present, oil recovery by heating mainly is by some technological measures reservoir temperature to be raise, oil well is if heat about 300 ℃, need with the heating of large-tonnage oil burning boiler, HTHP mass dryness fraction steam (320 ℃) is from the ground under the pipeline input well, and approach is long, heat-energy losses is big, power consumption excessive fuel consumption, contaminated environment, equipment are huge, difficult, maintenance is big, time-consuming, expense is high, deficiency in economic performance.Heat more than 300 ℃, all can't realize below 500 ℃.
The U.S. You Nisi fireflood production technique of introducing is to apply chemical combustion adjuvant under these conditions to light inflammable gas and liquid in the oil reservoir, and is combustion-supporting under a large amount of injections of pressure-air, makes oil reservoir burning heating, and ignition temperature can reach 800 ℃.Solidify oil and under HTHP drives, begin diluent stream to producing well, its shortcoming is that to light probability general, burn a large amount of energy, discharge a large amount of waste gas after burning and pernicious gas even acid solution, with the diffusion of combustion front, the material after the duration and degree of heating burning forms burnt shape thing and stops up fluid passage, air flue, a large amount of injections of cold high pressure air are meanwhile condensed the reservoir temperature sharp fall that burnt, influence oil flow greatly, influenced tar productivity, not very good.
The high-power device of single-phase extraordinary heating, equipment complexity, cost height, the high-power single-phase transformer of needs, and distribution facility, because power is too big, the phase line load is excessive, it is big that national grid is damaged, even damage, other various heaters all can't use under this environment, and the existing power supply facilities majority in oil field can't satisfy the instructions for use of single-phase heating at home.
For solving the existing great drawback of above-mentioned heating exploitation technology, how a kind of three-phase electrical equalization, high-power, overlength (more than 50 meters) are provided, high-quality specific use heating tube, the product tape that fills the domestic gaps is given the user.The inventor makes great efforts in seeking the perfect solution that prior art and overlength heating tube are made always.
The utility model content
The purpose of this utility model is to provide a kind of oil well three-phase overlength high-power heating tube, has enriched domestic oil field oil recovery heating technique.Can be at narrow and small bore pipeline, special environments such as high temperature, high pressure, high humidity, liquid, high corrosion use, and heat gas injecting mining as oil well, peat, the low-quality coalfield, unprofitable coalfield system air to open is adopted etc., comprises the special environment heating of heating.
Through a large amount of trial production processes repeatedly, the inventor leads high temperature heating magnesia heating tube and the three-phase oxidation magnesium cable from single-phase unskilled labourer and obtains enlightenment, found that vitrification magnesia (high insulation, heat-resisting good heat conductivity) merges technology mutually with high temperature heating metallic conductor and protective metal shell, the high-power Y of the three-phase of producing connects heating tube and has overlength heating (500 ℃), performances such as tension is shock-resistant, resistance to deformation, high temperature resistant, high humidity, high pressure, high corrosion.
According to this discovery; the insulation relation that reaches between the three-phase heating metallic conductor metal protection protector is reasonably handled in success; make Y connect the three-phase heating conductor and be wrapped between the protective metal shell, solved the difficult problem that three-phase power heats in the adverse circumstances of high temperature, high pressure, high humidity, high corrosion in the densification of vitrification magnesia.I have obtained brand-new breakthrough in manufacture craft is used, finally successfully develop the high-power heating tube of oil well three-phase overlength.
The technical solution of the utility model is:
The high-power heating tube of a kind of oil well three-phase overlength, this heating tube is bonded with each other by generate heat metallic conductor, magnesia, protective metal shell of high temperature, makes the overlength heating tube;
By the fine and close parcel of magnesia high temperature heating metallic conductor, high temperature heating metallic conductor triangularity safety equidistantly is fixed in the protective metal shell.
Protective metal shell is seamless, no leak source, and tension is shock-resistant, resistance to deformation, high temperature resistant, high humidity, high pressure, high corrosion.
High temperature heating metallic conductor Y connects end and is sealed in the heating tube termination, and fine and close rescue bag is rolled in the magnesia.
The beneficial effects of the utility model are:
1 heating tube is safe and reliable.This product is high temperature resistant, high pressure, high humidity, corrosion-resistant, shock-resistant, fire prevention, explosion-proof, anti-fracture, highly desirable mechanical strength and physicochemical property are arranged, install and use very convenient.
2, the high-power heating tube of three-phase overlength can be in long-term work below 500 ℃.The three-phase electrical equalization has the comparatively ideal thermal efficiency.
3, heating tube life-span height, its high temperature heating metal material has completely cut off air through the vitrification magnesia parcel of densification, makes it add the thermal life and prolongs greatly, can work under the condition of high temperature reliably and with long-term.Because the heating tube jacket portions has adopted alloy material, has stronger physicochemical property.
4, heating tube is easy to processing and manufacturing.That heating tube has is simple in structure, material purchases convenient, be easy to characteristics such as processing and manufacturing.
5, the operability of heating tube manufacturing.Heating tube is a machining, and streamline production alleviates manual labor, and it is safe and reliable, convenient to ensure the quality of products.
6, heating tube energy-conserving and environment-protective safety and environmental protection.The length of heating tube is similar to core intersection, is seated in oil layer section or coal seam section, heat is directly effectively brought into the place that needs heating with high pressure air drives.The heat waste of heating process is extremely low, thermal efficiency height.According to the oily situation in oil field, directly high temperature heats or lights fireflood and heat.There is above-mentioned several oil field heating production technique not have the advantage of comparable U.S..Because heating tube overlength performance need not just can reach the ideal long-term result of use to environmental disruption in special environment for use.
7, heating tube economy.The utility model is compared half the advantage with low, easy for installation succinct, safe and reliable, not enough other cost of cost with other oil well heating means, this heating tube be used for oil field heating exploitation, and low-quality coal system air to open adopt, hot spring adds to be pined for.
The factory that the utility model can be widely used in heating tube makes and the manufacturing of special cable factory, as: the overlength heating tube.
In a word, the utility model has been filled up the high-power specific use overlength of the three-phase heating tube blank of domestic production, have 200 ℃-500 ℃ of heating-up temperatures, high temperature resistant, high pressure, high humidity, corrosion-resistant, explosion-proof, fire prevention, anti-fracture, superpower tension, environmental protection, in light weight, applicability is wide, the life-span is high, workable and be easy to characteristics such as processing and manufacturing.
