In the recently held in the 2016 annual meeting and the eighth China energy energy executives on the BBS, China petrochemical group co., LTD. (hereinafter referred to as "sinopec") deputy chief engineer Wang Zizong on geothermal energy exploitation and utilization present situation and prospects of a keynote speech.Geothermal, he said, as a potential clean and renewable energy, in the process of countries to speed up the adjustment of energy structure, will certainly play an increasingly important role.During the period of "much starker choices-and graver consequences-in", sinopec geothermal development will make "20 smokeless city", implement new heating refrigeration area of 100 million square meters, at the same time, new geothermal power installed capacity of 500000 kilowatts.
Data shows, in the energy consumption structure, and increase non-fossil energy sources such as geothermal use of each percentage, equivalent to 37.5 million tons, alternative BiaoMei emissions about 94 million tons of carbon dioxide, sulfur dioxide, about 900000 tons, about 260000 tons, nitrogen oxides to our country to adjust energy structure, energy conservation and emissions reduction, environmental improvement is of great significance.
Sinopec has become the largest domestic conventional geothermal resources development and utilization of enterprises.In recent years, sinopec plan to promote development of geothermal industry to strategic level and promote the formation of the multiple well gathering, cascade heat exchanger, comprehensive utilization, tail water purification and mining filling and combining with the application technology system for the development of geothermal resources, created the world's first geothermal heating CDM methodology (modified), realize the fast development of geothermal industry.At present, sinopec geothermal development area expanded to 14 provinces and cities, geothermal heating area of more than 40 million square meters, implement alternative BiaoMei 1.2 million tons/year, carbon dioxide 3 million tons/year, become the domestic geothermal exploitation and utilization of the largest enterprises.
Xiong county in hebei province is known as "smokeless city", the basic realizing a complete coverage of the central heating of the heat of the city.Sinopec after six years of construction, xiong county in hebei implementation geothermal heating capacity of 3.85 million square meters, and built the techniques can be successfully copied, experience, to promote "xiong county model".Now rolling development to let city, wild, xinji, dongguang, cultural and other 15 city (county) area, hebei heating area of 12 million square meters.
Wang Zizong introduction, after several years of exploration and practice, sinopec is the development and utilization of geothermal resources exploration, industry layout, business model, technical system and so on various aspects of breakthrough, plan during the period of "much starker choices-and graver consequences-in" reengineering 20 smokeless city in the country.
In terms of resources exploration, sinopec currently cultivating formed hebei plain area, shaanxi, shanxi basin, north and southwest group of four scale exploration area, in order to speed up the resources of the geothermal development laid a solid foundation.During the implementation of the "much starker choices-and graver consequences-in" target "20 xiong county" target resource, initially formed in "three north" area heating, refrigeration is given priority to the layout of the southeast coast and the Yangtze river economic belt.
In terms of industry layout, sinopec has formed the beijing-tianjin-hebei, guanzhong, lu yu, shanxi "five regional development position", the three northeast provinces, including hebei heating area of 12 million square meters, the guanzhong region heating capacity of 6.2 million square meters, shanxi district heating area of more than 3 million square meters, lu yu region heating area of 7 million square meters, the northeast region of heilongjiang lindian file, liaoning and other places to scale development.
In the core technology, sinopec exploration in geothermal resources, geothermal resources evaluation, geothermal drilling suppling technology, geothermal tail water injection, cascade utilization of geothermal resources, information systems and so on six big domain formed the core technology system, effectively support the healthy and efficient development of geothermal industry.
In terms of business model, sinopec actively extend geothermal energy industry chain, is from the geothermal heating to the industrial waste heat and comprehensive utilization of residual gas and pressure development, from the deep geothermal to pay attention to the depth, river water and ground source heat pump, by general town to the city center breakthrough, by heating to the integration of power generation, refrigeration, modern, efficient agricultural extension, "+" of the heat of the development of new energy to realize the whole industry chain integration.
Geothermal energy exploitation and utilization of vast space in our country.National energy development strategy and energy planning: the proportion of non-fossil energy to 15% by 2020, to 2030 non-fossil energy increased to about 20% of the total primary energy consumption ".Development of geothermal industry not only to adjust the energy structure, energy conservation and emissions reduction, and improve the environment is of great significance, but also for countries to foster new industries, promote the people-oriented new urbanization construction, driving the development of related equipment manufacturing localization and engineering business, as well as to increase employment have obvious pull effect, is the construction of ecological civilization, the important measures to realize green development.
To promote the development of the geothermal industry, 17-18 November 2016, "2016 China international BBS and 240th of the heat of the China engineering science and technology BBS" will be held in Beijing.The BBS by national geothermal energy exploitation and utilization of research and application technology promotion center (hereinafter referred to as "the national center for geothermal energy"), the theme of "innovation, cooperation, green, cross".BBS invited including kuang-di xu, wang jiyang, edge, and so on more than 30 members and geothermal industry experts and scholars to attend, to explore solutions to geothermal energy development and utilization in the field of forward-looking, breakthrough technology and practical problems.
