北美石油工业二氧化碳提高采收率现状研究

环境保护受到高度关注,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,必须采取积极有效措施。应用CO2提高采收率是埋存CO2的重要途径,美国拥有应用二氧化碳提高采收率的成熟技术。CO2提高采收率包括混相驱油和非混相驱油2种方式,实现了最大CO2的埋存和提高原油产量有机结合,改善开发效果。北美提高采收率的机理和应用思路研究,必将为全球生态保护,石油资源的高水平、高效益开发和可持续发展提供理论及实践依据。

The Status of EOR Technology Using CO2 in North American Oil Industry

It attaches an importance attention to environment protection currently. While global warming caused by massively emission of greenhouse gas is becoming more and more serious. So active and effective measures should be taken to solve those problems. CO2 injection in EOR process is an important way for its storage. The mature EOR technology using CO2 is mastered by American. EOR technology using CO2 contains two ways-miscible and immiscible displacement. The technology combines CO2 storage and output enhance- ment of crude oil together, and will improve development effect of oilfield. Research on the mechanism and strategy of EOR technology using CO2 in American, will surely provide reference both in theory and in prac- tice for ecology protection, and for efficient & sustainable development of petroleum resource all over the world.
