| 摘 要： | 通过大量非均质和均质岩心物理模拟实验，给出了三元复合驱和聚合物驱替原油时的合理流度比，对于非均质岩心，三元复合驱和聚合物驱的流度比应控制在0.50-0.25。此时，三元复合驱采收率介于20.6%-24.0%之间；聚合物驱采收率介于13.3%-16.8%之间，对于均质岩心，三元复合和聚合物驱流度比应控制在0.50-d0.33，此时，三元复合驱采收率介于17.0%-19.1%之间；聚合驱采收率介于11.8%-13.1%之间。实验结果为矿场试验选择合适的驱替液粘度提供了依据。

| Abstract: | This paper performs a large number of heterogeneous and homogeneous core physical simulation experiments and gives the reasonable mobility ratio of polymer flooding, ASP flooding and oil displacement. The mobility ratio of ASP flooding and polymer flooding of heterogeneous core should be controlled between 13.3% and 16.8%. The ratio of homogeneous should be controlled between 0.50 and 0.33. At this time, the recovery factor of ASP flooding is 17.0%～19.1%, the recovery factor of polymer flooding is 11.8%～13.1%. Experimental result provides evidence for the selection of proper polymer fluid viscosity of pilot test. |
