摘要: 按Cotterman等对PHC方程的普遍化方法针对烃类将立方扰动硬链方程进行了普遍化,并按Pedersen等对“+”馏分的特征化方法将其应用于油藏原油的饱和压力、恒组成膨胀和微分释放过程的预测,所得计算结果与SRK、PR、PT和DG方程相比是令人满意的.通过计算实例,还阐明立方扰动硬链方程与范德华型方程相比是一种更为适用油气藏流体相态预测的热力学模型.

Abstract: The pure substance parameters determined for cubic simplified hard chain equation of state were generalized for hydrocarbons as functions of molecular weight,as coupled with the characterization procedure for C7+-fraction proposed by Pedersen et al.,the CSPHC EOS has been applied to predict the phase behavior of reseYvoir crude mils.The test results indicate that,the comparable or better predictions can be achieved as compared with SRK,PR,PT,and DG equations of state,the CSPHC EOS can be applicable to reservoir engineering.
