摘　　要：CO2是重要的工业产品,具有较高的商用价值,也是三次采油技术中应用较为广泛的注入剂之一。通过对CO2自身相态特征、开发过程、关井过程中地层流体相态特征研究,利用饱和蒸气压和临界条件辨别CO2在井筒内的相态,对CO2气藏的有效开发具有一定的指导作用。CO2 is not only an important industrial product with high commercial value but also one of the most widely-used injectants applied to tertiary recovery. According to a research on the phase-behavior property of CO2,and that of formation fluid during development and shut-in,our study distinguishes the phase behavior of CO2 in wellbore through saturated vapor pressure and critical condition. It provides guidance for effectively developing CO2 gas reservoir.
