摘　　要：使用双管并联长岩心填砂模型和五点法层间非均质模型,模拟研究聚合物溶液和微凝胶体系的流动特征、分流作用和剖面调整能力,探讨微凝胶与低浓度聚合物交替段塞组合的调驱性能和驱油效果,为提高采收率组合驱油方法提供实验依据和理论指导。The flow properties, fractional flow and profile modification effect of polymer solution and micro-gel system were tested, and combination flooding of polymer slug with micro-gel slug were experimented in parallel super-long core and heterogeneous inter-layer models. The results and mechanics of combination flooding were discussed in order to provide experimental evidence and guide for different combination flooding design for field tests. The results showed that combination flooding increased oil recovery than either polymer flooding or micro-gel flooding, because it made good use in both the in-depth profile modification of micro-gel slug and the mobility control of polymer slug properly and alternatively.
