| 摘 要： | 提出了用细管驱替法测定ＣＯ＿２与正辛烷、正十四烷最小混相压力的方法，研究了液相的组成和温度对最小混相压力的影响；将所测定的值与前人所建立的有关关联式、关联图的预测结果做了比较。结果表明，细管法是可靠的，可推广应用于混相驱生产方案的制定；由实验结果发现，油相组成对注ＣＯ＿２体系最小混相压力的影响很小，但随着温度的升高，最小混相压力增大。

| Abstract: | The minimum miscitility pressure(MMP)of CO_2-normal octane and nofmaltetradecane systems were measured and the effect of liquid composition and experimentaltemperature on the MMP were investigated.The measured results are compared with theexisting correlations.An experimental method for determining MMP of driving gases inreservoir flulds by slim tube displacement method was established.The molecular weight ofthe solvents has only a slightly effect on the MMP,while the MMP will be increased with theincreasing of temperature. |
