摘　　要：对近临界流体的特殊性质进行了描述,并对近年来经典和非经典状态方程在近临界流体PVT相态特征模拟计算方面的发展及应用现状进行了总结,指出要找到适用于近临界流体的状态方程还有很多工作要做,需要大量的实验数据支持以及理论上的突破。同时它的发展在近临界油、气藏开发工程、注气驱油藏开发工程中具有广泛的应用前景。In this paper, we describe the characteristics of near critical hydrocarbon system and summarize the development and application of empirical and unempirical EOS in near critical fluid about PVT phase analog. A lot of experiments should be done in the future in order to find out an EOS which is suited to near-critical hydrocarbon system and obtain a theoretical breakthrough. Meanwhile, the EOS application should have a widespread prospect in near-critical hydrocarbon development and injection gas displacement development.
