Abstract
The present invention relates to a technique for comprehensive utilization of waste heat of oilfield produced liquid, and provides a technique with safety, environmental protection, and low operational pressure and can steadily provide hot water for an air-conditioning or industry and living. The heat of the oilfield produced liquid or oil waste water is transmitted to warming hot water and living and industrial hot water by that the present invention makes use of a heat exchanger. The warming hot water transmitted to heat exchanging equipment of a fan coil or the heat exchanger, etc. is used for production of the hot of buildings. The warming hot water is circulated in the heat exchanger after the cooling of the hot water by the buildings. The present invention absorbs the heat by making use of the fan coil or the heat exchanger pumped by an underground water pump, and the heat is delivered into a water injection well or pumped to the building and entry into the heat exchanger for the releasing of the hot by the fan coil, etc. After adopting the technical processes, the hot water ranging from 30 DEG C to 69 DEG C or chiller water ranging from 10 DEG C to 15 DEG C is provided by the waste heat of the oil well produced liquid or the oilfield waste water.
Description
One, technical field:
The present invention relates to a kind of technology of oil field produced fluid residual heat comprehensive utilization, especially a kind of oil field mining liquid, oilfield sewage waste heat system warm up, provide life, industrial hot water and groundwater refrigeration technology.
Two, prior art: there be produced-water reinjection liquid and the oil well produced liquid after crude oil is separated in a large amount of oil fields in China, and only Shengli Oil Field is with regard to 400,000,000 tons/year, and this fluid temperature has higher value between 30 degrees centigrade to 70 degrees centigrade; Utilize oil well produced liquid, oilfield sewage heat energy to provide required coupling temperature water source for building or production, life, utilize the characteristic of underground constant temperature to be architecture refrigerating, the underground constant temperature of heat energy and oil field of oil field mining liquid, produced-water reinjection liquid is efficiently utilized, and, any energy no longer burns, accomplish safety, environmental protection, the harmonious environment thermal energy that utilizes, no longer be to use compressor, and save a large amount of electric power equal energy sources, be reached for the building heating, provide temperature at 30 ℃ to 69 ℃ industry or domestic water, perhaps be architecture refrigerating summer.Utilize the warm and underground refrigeration process of oil field mining liquid, oilfield sewage waste heat system reducing potential safety hazard, environment is not had on the basis of any pollution, compare with tradition fire coal, combustion gas, fuel oil, electrical heating, heat pump, energy savings is more than 94%, and mechanical moving element is few, not fragile, life-span is long, and maintenance is convenient.
Three, summary of the invention:
The object of the invention provides that a kind of safety, environmental protection, operating pressure are low, system is simple relatively, reliable, efficient is high, operating cost is low, corrosion-resistant, good antiscale property, can stablize air-conditioning or industry, the life technology with hot water is provided.The oil field produced fluid residual heat comprehensive utilization process is to utilize oil well produced liquid or oilfield sewage through heat exchanger, send heat to heating hot water, life, industrial hot water, heating is sent to heat transmission equipments such as fan coil, heat exchanger with hot water by pipeline, being used for building heats, after heating was dispelled the heat through building with hot water, the heat to heat exchanger absorption source extraction liquid circulated again.Utilize underground water intake well to take out underground water, underground water pump to fan coil or heat exchanger draw heat, the one, heat absorption back underground water is transported to water injection well through water injecting pump; The 2nd, by the cooling water of heat exchanger, after pump to building absorbs its space heat by heat transmission equipments such as fan coils, enter the heat exchanger release heat.After adopting above-mentioned technological process, oil well produced liquid, oilfield sewage waste heat provide 30 degrees centigrade to 69 degrees centigrade hot water, with industry, heating for residential area, summer, utilize underground water to carry 10 ~ 15 degrees centigrade chilled water for building.Oil well produced liquid, the warm energy source that reaches underground refrigeration process of oilfield sewage waste heat system are heat energy, the stability of thermal source, sink temperature has determined the stability of hot water, cold water, compare with other thermals source, oilfield extraction liquid (oilfield sewage), underground water can provide stable temperature.Device therefor of the present invention is except that heat exchanger requires anticorrosion, antiscale, double-current journey, and other heat exchanger, valve, pump all do not have special removing and require.
