摘　　要：二氧化碳驱油技术是一种比注水开采更能提高原油采收率的方法。该技术既可适用于埋藏深、储油物性差的油藏,也可适用于低渗透、高粘、高凝油等难开采油层;既可适用于油田的中后期开采,也可适用于新油田的开发。自20世纪50年代美国开始二氧化碳驱油技术研究以来,我国二氧化碳驱油技术发展迅速。中原濮城油田通过在沙一油藏实施二氧化碳驱油技术,见到了明显的增油效果。目前,该技术已经成为油田驱油增产的关键技术。Carbon dioxide flooding technology is a more than water flooding that can enhance oil recovery method. The technique can be applied to deep buried reservoirs,and where reservoir physical property is poor. Also it can be applied to low permeability,high viscosity,and high pour point oil layers which are difficult to exploit. The technique is applicable to the middle and later periods of oil field exploitation,as well as the development of new oil fields. Since the study of the technology of carbon dioxide flooding in America in the 50 ＇s of the last century,the technology has developed rapidly,and obtained obvious effects of increasing oil production when implemented in Sha-1 reservoir,Pucheng oil field. Now it has become the key technology of oil production in oil fields.
