Abstract: The information and results of MEOR study and application have been compiled in this paper. In China,great progress have been achieved on research of strains and mechanism in laboratory,many kinds of formation have been candidates as field pilots to conduct microbial treatment or microbial enhanced waterflooding. The results show microorganism can increase oil production and decrease water cut. The technology of MEOR will become an important method in improving oil recovery in China.

Key words: microbial enhanced oil recovery, strain, mechanism research, field test

摘要： 简要阐述了微生物采油技术、微生物采油技术的发展及微生物采油优势。介绍了用于微生物采油的自然菌和工程菌以及我国微生物采油菌的分离、筛选、产物分析、提高采收率机理研究的方法、采用手段和所取得的研究成果,在对微生物采油机理研究基础上提出了微生物采油数学模型。分析我国微生物采油矿场试验的成败后,指出微生物采油更适合于我国下列油藏;小于40℃的低温油藏;普通稠油油藏;含蜡油藏;含水小于80%的断块小油藏。
