摘　　要：根据胜利油区已实施微生物驱油矿场实践认识,对影响微生物驱现场试验效果的主要因素进行了分析。从微生物驱油藏开发效果改善和微生物见效特征两方面,评价了现场试验明显见效区块的提高采收率潜力和见效特征,表明在现场实施工艺配套的基础上,微生物驱油技术能够改善油藏环境的微生物生态结构,抑制综合含水上升,提高试验区采收率,在水驱开发后期具有良好的应用前景。According to the field practice and recognition of microbial flooding in Shengli Oilfield,the main factors influencing the effect of microbial flooding in the oilfield were analyzed. From the aspects of improvement of development effect of microbial flooding and microbiological responding characteristics,the potential and microbiological responding characteristics of oil recovery improvement were evaluated. The result shows that on the basis of its matched techniques,the techniques of microbial flooding can be used to improve the ecologic structure of reservoirs inhibit the increase of integral water cut and raise the oil recovery ratio in tested area and it has good application prospects.
