摘　　要：为了利用微生物技术进一步提高原油采收率,针对S12区块开发现状和地质条件,通过对油藏内部的微生物群落结构组成、地层流体的性质进行分析,确定了实施内源微生物驱油技术的可行性。通过大量室内试验筛选了可以激活油藏中利于采油细菌的营养配方,并通过物理模拟试验确定了激活剂的注入浓度,物理模拟试验结果表明,在进行水驱之后,实施内源微生物驱油技术可提高采收率9个百分点以上,在室内试验的基础上进行了现场注入试验。现场跟踪测试结果表明,注入筛选的营养剂配方以后,油藏中的细菌被激活,并代谢产生了有利于提高原油采收率的物质,起到了一定的增油效果。In view of exploitation and geology situation of S12 block,component of microbe and properties of fluid of reservoirs was studied,practicability of microbe oil displacement was identified.Nutritional formula to active microbe oil displacement was selected by laboratory experiment,and concentration of activator was simulated,test result shows that it can improve oil recovery over 9% after water flooding reservoir.Field test demonstrate that it can active bacterium of reservoir after injecting selected nutritional formula,and generated subject which can improve oil recovery.
