摘要 对确定注气混相驱最小混相压力(MMP)的方法进行了总结,包括实验法、经验关联法和计算法.对各方法的局限性进行了分析,并简要地阐述了多混合单元方法(MMC)的研究进展.研究结果表明,尽管细管实验法耗时、费用高、精度低,但它仍是用于确定MMP的最好的实验方法;在确定MMP的方法中,对于复杂体系,特别是三相体系,MMC模型是最简单、快速、稳健的,其计算准确度取决于使用的EOS;未来的研究方向是纳米尺度中复杂体系的MMP的确定方法. The methods for determining the minimum miscibility pressure(MMP)for gas injection miscible flooding including experimental method,empirical correlation method,and calculation method are summarized,the limitations of the methods are analyzed,and the progress of research on multiple mixing cells(MMC)method is introduced briefly.The results of research have shown that slim-tube experimental method is the best experimental method for determining MMP although it is time consuming,costly,and low in accuracy and that MMC model is a simple,rapid,and robust method for determining MMP especially in a complex system,three-phase system in particular,with its accuracy dependent upon the EOS used among the various methods for such purpose.The future research will be the methods for determining MMP in the complex system of nanoscale.
