摘要
使用Ｐ－Ｒ立方型状态方程和作者提出的Ｐ－Ｒ方程新的混合规则预测了三元非对称油藏流体ＣＯ＿２－ＣＨ＿４－ｎ－Ｃ＿１６Ｈ＿（３４）的高压汽液平衡，并与试验数据进行比较，其泡点压力的平均绝对百分偏差介于３％和１２％之间，较好地改进了Ｐ－Ｒ方程对多组份油藏流体高压汽液平衡的预测功能。
In this paper,high pressure vapor-liquid equilibria are calculated for a ternary asym-nletrical reservoir fluid CO_2-CH_4-n-C_16H_(34) using P-R equation of state and new mixing ruleswhich are proposed by the authors.The results are compared with experimental data. Theabsolute average percentage deviations of bubble point pressure are between 3%and 12%. This method markedly improves the prediction of vapor-liquid equilibria for multi-component reservoir fluid.
