摘　　要：二氧化碳驱可通过二次或三次采油而应用于油田,该技术不仅可以提高采收率,而且可以解决二氧化碳的储存问题,保护空气环境,抑制温室效应。介绍了二氧化碳驱油的驱油机理,各种注入方法的特点以及国内外的应用情况。在能源短缺,节能减排的大背景下,二氧化碳具有广阔的推广和利用前景。carbon dioxide flooding can be applied to oil fields through secondary or tertiary oil recovery.This technology can not only improve oil recovery,but also solve the storage problem of carbon dioxide,protect the air environment and inhibit the greenhouse effect.This paper introduces the displacement mechanism of carbon dioxide flooding,the characteristics of various injection methods and the application at home and abroad.Under the background of energy shortage,energy conservation and emission reduction,we can see that the flooding of carbon dioxide has a broad prospect of promotion and utilization.
