全球气候变化是人类迄今面临的既重大又复杂的环境问题,由于温室气体大量排放而引起的全球气候变暖问题日趋严峻，正在严重地威胁着人类赖以生存的环境，国际社会必须采取积极有效措施。2006年中国国家科技部批准国家“九七三”项目——温室气体提高石油采收率的资源化利用及地下埋存研究。建立适合中国国情的CO₂高效利用和埋存体系；实现CO₂减排的社会效益和CO₂高效利用的经济效益；发展适合中国国情的CO₂埋存地下理论、多相多组分相态理论、多相多组分非线性渗流理论和CO₂捕集与储运理论。通过上述基础研究，形成具有自主知识产权的CO₂地质埋存和高效利用的综合技术，使中国CO₂安全埋存—高效利用研究处于国际水平。必将为全球资源和环境的高水平、高效益开发和可持续发展提供理论及实践依据。

Global warming is the most serious environmental problem that we ever had. One of the reasons for that focus on the mass emission of greenhouse gas has made the cosmopolitan warming problem more and more serious. It is such a great threaten to our environment that the international community must take active and effective measures. In 2006, a 973 project named "Research for Utilizing Greenhouse Gas as Resource in EOR and Storaging It Underground "  was authorized by The Ministry of Science and Technology of the People's Republic of China. The researches include establishing a system suits China`s national conditions and sequestrate CO₂ effectively, obtaining society benefit from reducing CO₂ emission and obtaining economic benefit from CO₂ utilization, developing CO₂ storage theories, phase state of multiphase and multicomponent mixtures, nonlinear percolation mechanisms of multiphase and multicomponent mixtures and CO₂ capture & transport.. In China the CO2 sequestration security and the efficient use of research is at the international level. From those basic researches above, it is expected to get state owned CO₂ storage and utilization technology, which will be served as useful theory and practice basis for efficiently global resource & environment development and sustainable development.
