| 摘 要： | 根据渤海SZ36-1油田H区块水驱油藏条件、水质及基础菌群特征,为提高微生物驱油效果,采用室内实验方法筛选了营养凝胶类型,并评价了其性能和配伍性。采用岩心驱替实验和数值模拟方法,优化了营养凝胶和微生物驱剂段塞组合和注入体积,结果表明,营养凝胶辅助微生物驱油效果最好,营养凝胶可以增大微生物驱剂在油藏中的滞留时间,同时产生营养成分缓释作用,激活油藏深部微生物菌群。

| Abstract: | According to water drive reservoir conditions,water quality and basic flora characteristics of H block in Bohai SZ36-1 oilfield,in order to improve the effect of microbial oil displacement,the indoor experiment method has been adopted to screen out nutritious gel type,and then its performance and compatibility have been evaluated.With the core displacement experiment and numerical simulation methods,the combination of nutritious gel and microbial flooding agent slug,and the injection volume have been optimized.The results indicate the nutritious gel-assisted microbial flooding on oil displacement effect is the best,and it can prolong the retention time of microbial flooding agent in oil reservoir,meantime,it can produce nutrients to activate microbial flora in deep reservoir. |
