摘　　要：本文介绍近十几年以来大庆油田利用具有产气、降解原油、产生物表面活性剂及堵调性能的菌剂,通过地下发酵,开展微生物采油现场试验取得的进展。分析了该项技术适用的油藏条件和应用特点。截止到2012年底,应用微生物采油技术增产原油达12×104 t。其中微生物单井吞吐518口,累计增油6.3×104 t,实施微生物驱和调驱项目10项(45个井组),累计增油5.7×104 t,为大庆油田稳产发挥了重要作用。Microbial enhanced oil recovery （MEOR） is a technology that utilizes bio-gas, bio-surfactants, bio-polymers and degradation produced by underground fermentation of bac- teria for petroleum exploitation. In this study, it is introduced that progress in pilot tests of MEOR in Daqing Oilfield in recent decades, which analyzes suitable reservoir conditions and application characteristics. By the end of 2012, cumulative incremental oil production reached to 12×10^4t, including 518 wells by single-well microbial huff-and-puff with cumulative incremental oil production of 6.3×10^4t, and 10 projects （45 well patterns） by microbial flooding and profile modification with cumulative incremental oil of 5.7×10^4t. The technology plays an important role in stabilizing production of Daqing oilfield.
