摘　　要：国外注CO2混相和非混相驱油技术已在低渗透油藏中得到了广泛的应用。本文在阐述CO2混相和非混相驱提高采收率原理基础上,系统整理和归纳了实施CO2驱油藏的适应性和混相驱、非混相驱筛选标准。通过国内外低渗透油藏注CO2驱提高采收率应用情况分析,指出CO2驱能起到明显的增油降水和提高采收率的效果,提出应积极开展注CO2驱油技术的研究和现场试验的建议。Carbon dioxide miscible and non-miscible flooding technique has been widely applied abroad in low permeability reservoirs.In the paper,carbon dioxide miscible and non-miscible flooding mechanism of EOR is discussed,and reservoir adaptability by carbon dioxide flooding and the corresponding screening criteria are systematically summarized.According to actual application analysis of carbon dioxide to enhance oil recovery in low permeability reservoir at home and abroad.It is put forward that carbon dioxide can increase oil and decrease water,and enhance oil recovery.In addition,Suggestions of actively developing carbon dioxide technique research and field test are offered in the end.
