摘　　要：CO_2混相驱油方法被认为是现代驱油技术中,比较好的提高采收率方法。检测一个油藏是否能达到混相的条件是这个油藏的地层压力与最小混相压力进行比较,看是否高于最小混相压力。如此说来,确定最小混相压力就显得很有实际意义。通过研究最小混相压力,分析组分、温度、CO_2的不纯度对混相压力的影响。In recent years, CO_2 miscible flooding method is considered as a better enhanced oil recovery method in modern flooding technology. Detecting whether a reservoir to achieve miscible conditions is to compare the formation pressure with the minimum miscibility pressure, so to determine the minimum miscibility pressure has very practical significance. By studying the minimum miscibility pressure, effect of component, temperature and CO_2 purity on the miscible pressure was analyzed.
