详细介绍了CO2驱油与埋存研究的现状。目前CO2驱油在国外已取得较好的经济效益，在国内正在进行矿场先导试验。而CO2埋存在国内外均处于探索阶段。CO2驱油与埋存研究中存在的问题主要包括提高采收率方面的扩大波及体积等关键问题、CO2埋存介质和方法的选择、CO2驱油对地层的伤害、CO2驱油与埋存的气源问题、CO2驱油与埋存产业协调和整体规划5大方面。指出了该项研究的发展趋势。图2表2参38

The current situation of CO2 displacing oil and CO2 sequestrated researches was reviewed.Nowadays,CO2 displacing oil had got good economic benefits outside and was carried out oil field experiment inside.And CO2 sequestrated researches were in exploring stage all over the world.The key problems in CO2 displacing oil and CO2 sequestrated researches contained five parts,such as enlarging sweep volume of EOR,carrier and medium choice of CO2 sequestrated,the formation damage in the process of CO2 displacing oil,air source,industrial coordination and overall planning.Finally,several development directions of CO2 displacing oil and CO2 sequestrated researches were proposed.
