Abstract: In order to evaluate the field test effects of the endogenous microbial flooding in Daqing Oilfield, the oil-water interfacial tension, biochemical indexes of the produced water, bacterial community structures and oil produc-tions before and after the activation are analyzed. The results show that the oil-water interfacial tension is reduced by 25% after the injection of nutrients, some acetic acid, lactic acid and other low-molecule organic acids are pro-duced; after the activation of the nutrients, the bacterial community structures are simple and the dominant bacteria are Arcobacter sp., Acinetobacter sp., Thauera sp. and Clostridium sp.; the average daily liquid production of the block is increased from 456 t to 528 t, and the daily oil production increased from 15. 2 t to 28. 5 t. The nutrients injected in the field test have activated the beneficial bacteria and furthermore have realized the purpose of enhan cing the oil recovery.
Key words: endogenous microbial flooding (MEOR) ; field test; nutrient; bacterial community structure
