聚合物微凝胶组合驱油效果实验研究

An Experimental Study on the Combination Flooding of Polymer Slug and Micro - gel Slug

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。

Abstract: 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-l
