本文根据检查井水淹层岩心细菌分析结果，研究了注水油层不同类群微生物生长的特点。油层注入淡水以后，把地层水冲淡，同时也带进了微生物和其营养物质，尤其是污水回注之后更是如此，这就加强了微生物在地层中的活动。这是引起油层堵塞和设备腐蚀的重要因素。文献〔1〕—〔5〕先后研究了油层注水后细菌发育状况。
Based on the analysis of core bacteria in the water flooded layer of the inspection well, the characteristics of microbial growth in different groups of waterflooding oil layers were studied. After fresh oil is injected into the reservoir, the formation water is diluted and brought in with microorganisms and their nutrients, especially after reinjection of the wastewater, which enhances microbial activity in the formation. This is an important factor that causes clogging of the reservoir and equipment corrosion. Literature [1] - [5] has studied the development of bacteria after water injection.
