The recent victory oil field has been demonstrated through a project called "feasibility study on the feasibility study of steam thermal extraction technology". Researchers will clean nuclear power for the first time the introduction of oilfield development, the project research at home and abroad is first, if you can implement at home and abroad to fill in the application of thermal recovery of heavy oil development in this field blank.
Thermal recovery of heavy oil development is a "hot oil change" development mode, with shengli oilfield as an example, the annual output of 5 million tons of annual average steam injection of over 9 million tons, mainly USES the fuel system of boiler steam/coal way, high energy consumption, pollution, high cost of steam. The research shows that the cost of the viscous oil injection system is more than 65 percent of the cost of heavy oil. The method of conventional exploitation of light oil is not suitable for the exploitation of viscous oil, so it is urgent to solve the problem of the technology of heavy oil extraction. Way along with the development of heavy oil conversion and the enhancement of environmental protection standard, the traditional way of making steam already can not meet the current low oil prices decline, the urgent request of the efficiency, energy conservation, environmental protection and so you need to break the traditional thinking, develop the new system of energy conservation and environmental protection, low cost of steam method.
The use of clean nuclear energy instead of organic fuel for heavy oil extraction has been put into the researchers' field of view. The high energy of high temperature and high pressure small nuclear reactor, less material consumption, low cost, low radioactive source and high security, for thermal recovery of heavy oil development provides a new type of thermal recovery. According to one kilogram of uranium fission, which is equivalent to 2, 500 tons of high quality coal, it will save a lot of the fossil materials and liquefied fuels used in heating, and reduce the pollution of the environment.
Oilfield based on the actual needs, research and development of the small pile of high temperature gas cooled module is capable of producing 16 million mpa, 950 ℃ of supercritical thermal steam for thermal recovery of heavy oil development, at present the technology to convert the steam cost is 108 yuan, equivalent to the original use half of the cost of steam injection boiler. But the high temperature supercritical state challenges the new understanding of the process and mechanism of thermal extraction. It will greatly improve the economy and the way of oil production, as long as we overcome the high temperature and high pressure and high pressure technology of heat extraction process.
