摘　　要：随着一些油田开发进入后期,注水开发以及一些三次采油技术已经不能再提高采收率,这时CO2驱作为一项提高原油采收率的技术在现场得到了广泛应用。目前,此项技术在美国、加拿大等国的应用已较成熟。我国对该技术的研究相对较晚,对该工艺还需要深入研究。在国内,随着CO2气源的发现,此项技术正在被越来越多的油田应用。本文在调研国内外大量文献资料的基础上,阐明了CO2提高原油采收率的机理,注水方式以及CO2驱提高采收率的研究现状及进展,并总结了适合CO2驱目标储层的筛选标准。With some oil-field development entered the later period,the water-injection development as well as three extraction technology already could not raise the recovery ratio any more,by now CO2 flooding technology to raise the crude oil recovery ratio,which obtained the widespread application in the scene. At present,this technology has already applied in US,Canada maturely.Our country is relatively late to this technology,also needs to be deeply researched to this craft.In China,with the discovery of CO2 source,this technology has been applied more and more in oil field.On investigating and studying massive literature materials in both the domestic and foreign,This article had expounded the mechanism of CO2 raising the crude oil recovery ratio,the irrigation way as well as the research present situation and the progress of CO2 driving to raise the recovery ratio.And summarized the screening standard goal reservoir which suited CO2 to drive.
