Combustible ice-mining technology has reached the international advanced level in China reserves than oil | combustible ice _ news

[Observers network] ice breakthrough advances in mining technology in China! According to Xinhua News recently, after more than 10 years of research, Jilin University research team developed key technologies of thermal recovery of cold gas hydrate drilling on land, fill the domestic gap in this area, generally reached the international advanced level. In addition, this technology won the 2016 State technological invention award.
Combustible ice found in deep-sea sediments or terrestrial permafrost, is from natural gas and water in class ice-like crystals formed under conditions of high pressure and low temperature materials, combustion will generate only a small amount of carbon dioxide and water, much less pollution than coal, oil and natural gas, but 10 times times more energy.
In addition, the combustible ice huge reserves, which is equivalent to the total organic carbon resources known coal, oil and natural gas twice times the amount, is internationally recognized for the replacement of oil and natural gas energy.
Jilin University in China since 2004, combustible ice drilling project on land development, capturing the high altitude and cold area and a number of technical problems, successfully developed the first at home and abroad flammable cold with independent intellectual property rights of key technologies of thermal recovery of drilling.
Muli basin, Qinghai province, at an altitude of 4000 meters, team drills for the first time using this technology by terrestrial physical samples of combustible ice, and land successfully test-fire ice mining, breaking the monopoly of foreign gas hydrate drilling sampling tech.
International universal "packing insulation passive sampling" drill, different, new technology first "active cooling freezing sampling principle", invented the drilling mud intensive cooling method, hydrate hole fast freezing sampling method and the end of mining technology of high-temperature pulsed thermal excitation, the main technical indicators than similar foreign technology.
China geological learned hired China engineering hospital academician Su Yi brain, and Kang Yuzhu,, Chinese Academy of Sciences academician Li Tingdong, on project research results for identification, and made evaluation, gas hydrate of drill mining is General gas development in the of worldwide problem, the project for this a major strategic technology reserves needs for technology research, for China land domain gas hydrate of major found and success try mining provides technology support, General reached international advanced level.
At present, in the exploration of combustible ice research, United States Japan and other countries have achieved great results, but failed to realize the large-scale exploitation of combustible ice. This stage converted to commercial-scale development and production phases, as well as economic, geological disasters, the environment and other issues to consider.
The team also said that because of natural gas hydrate resources found mainly in the waters next team will research on marine gas hydrate drilling and production technology, to contribute to the early realization of commercial exploitation of natural gas hydrate in China, and "along the way" strategy.

中国可燃冰开采技术达到国际先进水平 储量远超石油|可燃冰_新闻资讯

[观察者网 综合]中国可燃冰开采技术获得突破性进展！据新华社近日消息，经10余年技术攻关，吉林大学科研团队研发出陆域天然气水合物冷钻热采关键技术，填补了国内该领域空白，总体达到国际先进水平。此外，该技术还获得了2016年国家技术发明奖二等奖。
可燃冰分布于深海沉积物或陆域永久冻土中，是由天然气与水在高压低温条件下形成的类冰状结晶物质，燃烧后仅会生成少量的二氧化碳和水，污染比煤、石油、天然气小很多，但能量高出十倍。
此外，可燃冰储量巨大，所含有机碳资源总量相当于全球已知煤、石油和天然气总量的两倍，被国际公认为石油、天然气的接替能源。
中国吉林大学从2004年开始开展陆域可燃冰钻采项目研发，攻克了高海拔和严寒地区施工等多项技术难题，成功研发了国内外首创的具有自主知识产权的可燃冰冷钻热采关键技术。
在海拔4000公尺的青海省木里盆地，科研团队利用该技术首次钻获陆地可燃冰实物样品，并成功实现了陆地天可燃冰试开采，打破了国外水合物钻探取样技术的垄断。
与国际上通用的“被动式保压保温取样”钻探原理不同，新技术首次提出“主动式降温冷冻取样”原理，发明了钻井泥浆强化制冷方法、水合物孔底快速冷冻取样方法和高温脉冲热激发开采技术，主要技术指标超过国外同类技术。
中国地质学会聘请中国工程院院士苏义脑、康玉柱，中国科学院院士李廷栋等对项目研究成果进行鉴定，并做出评价，天然气水合物的钻采是非常规天然气开发中的世界性难题，该项目针对这一重大战略性技术储备需求进行技术攻关，为中国陆域天然气水合物的重大发现和成功试采提供技术支撑，总体达到国际先进水平。
目前，在可燃冰的勘探研究上，美国日本等国家都获得了长足的研究结果，但是都未能实现可燃冰的大规模开采。这个阶段转换到商业规模的开发生产阶段，还有经济、地质灾害、环境等问题需要考虑。
该研究团队也表示，由于天然气水合物资源主要分布于海域，下一步该团队将针对海域天然气水合物钻采技术开展研究，为中国天然气水合物早日实现商业化开采做贡献，并为“一带一路”战略服务。
