After nearly half a century of development, microbial enhanced oil recovery technology has a great progress. Field trials and studies have shown that microbial enhanced oil recovery technology can better fit a certain type of reservoir, and is easy to operate, and its cost is lower, and it has no pollution to the environment, so it has broad application prospects and has been concerned at home and abroad. Oilfield chemical is an important factor to affect the microbial metabolism. How to play the role of chemicals in microbial enhanced oil recovery process and minimize its negative effects is an important part of the microbial enhanced oil recovery technology.% 经过近半个世纪的发展，微生物采油技术已获得了较大的进展，现场试验和相关研究表明，微生物采油技术能够较好的适合一定的油藏类型，且操作简便，费用较低，对地层与环境无污染，具有广阔的应用前景，受到了国内外的广泛关注。油田化学剂是影响微生物新陈代谢的重要因素，如何在微生物采油的过程中发挥化学剂的促进作用，减少其不利影响，是微生物采油技术的重要环节。
