| 摘 要： | 相态拟合为组分模型提供了所需的各组分状态参数，拟合的好坏决定其提供的状态参数能否准确表征实际流体性质。本文以低渗透油藏CO2驱原油相态拟合过程为研究对象，对重馏分特征化、拟组分划分、实验曲线回归计算的原则、影响因素、方法进行研究，形成了一套适用于CO2驱的原油相态拟合方法，从而提高相态拟合精度并节省相态拟合的时间。

| Abstract: | Since phase matching provides state parameters of each composition for compositional model, the quality of matching would influence the characterization precision of fluid properties by state parameters. This paper mainly discussed the rules, influence factors and method of the heavy component splitting, pseudo-component lumping and experiment curve regressing. A suit of method has been formed, which helps to promote the matching precision and shorten the matching time. |
