| 摘 要： | 为了评价JYC聚合物微球乳液调驱技术在非均质油藏中的适应性,通过室内物理模拟实验,测定了纳米级JYC微球乳液在非均质物理模型中分流量的变化规律;通过并联模拟岩心驱油实验,分析了不同浓度和注入量的微球乳液提高采收率效果,优化注入段塞.实验结果表明:新型微球乳液性能稳定且注入性良好;能够有效改善注入水在非均质储层中的分流量,扩大波及体积,启动低渗层原油,且能提高水驱后高渗层的驱油效率;适宜注入质量浓度为2 000 mg/L,注入量大小和储层非均质性密切相关.该调驱技术能够有效改善非均质油藏开发效果,进一步提高原油采收率. |

| Abstract: | In order to evaluate the adaptability of JYC polymer micro-sphere emulsion flooding in the heterogeneous reservoirs,the variation of the fraction flow rate of the polymer micro-sphere emulsion is measured in heterogeneous physical simulation through physical simulation experiments.The effects of the concentration and injection volume of the emulsion on recovery factor are analyzed through the parallel simulation core flooding experiments,and the injected slugs are optimized.The results show that:JYC micro-s... |
