For the last 20 years Shengli oilfield has done research into the application of microbial enhanced oil recovery (MEOR). The authors summarize and analyze MEOR progress in mechanism research and field application in Shengli oilfield. The results indicate MEOR could improve oil recovery after water flooding and polymer flooding with multiple mechanisms. Cumulative oil increment of MEOR application on seven blocks was 212,366 t. The research and application of MEOR should concentrate on air assisted microbial flooding and indigenous microbial flooding in the future. [ABSTRACT FROM AUTHOR]

The authors have summarized and analyzed the research and application of biological treatment on the oil production wastewater of Shengli oilfield. The results indicated that the biological wastewater treatment technology had special advantages in removing dissolved oil, emulsified oil, and other organic pollutants. By biological treatment or combining it with other process, oil production wastewater can be discharged, reinjected, or recycled effectively. Biological technology plays an important part in solving the problem of wastewater in the petroleum industry. [ABSTRACT FROM PUBLISHER]
