| 摘 要： | 应用物理模拟方法,研究了聚驱后不同化学驱提高采收率效果的差异及其驱油机理.实验过程中,利用饱和度监测技术测量物理模型剩余油饱和度的变化规律.实验结果表明,聚驱后通过井网加密和化学驱结合可进一步提高采收率,在实验设计的几种驱油方法中,三元复合体系驱油效果最好,聚驱后采收率提高值达到了17.2%.饱和度场分析表明,低渗透层主要是通过扩大波及体积,高渗透层主要是通过提高驱油效率的机理来进一步提高聚驱后采收率,所以在选择聚驱后驱油方法时应综合考虑扩大波及体积和提高驱油效率的双重驱油机理. |
| 关 键 词： | 一次聚驱 聚驱后化学驱 采收率 含水率 含油饱和度 |

| Abstract: | The results of different chemical oil displacement forms after polymer flooding and their EOR mechanisms are studied by physical simulation.The remaining oil saturation of the physical model is monitored in the simulation experiments.The results demonstrate that,the oil recovery factor could further be enhanced after polymer flooding by combining well pattern infilling with chemical flooding.Of several simulated chemical flooding forms,ASP compound system has the best oil displacement result,and it can furt... |
