摘　　要：针对油层原油性质 ,在室内模拟井下条件 ,通过测定处理前后油井产出的原油组成 (含蜡量和烃组成 )和物性 (凝固点、粘度 )、原油伴生水中有机酸的含量和水的表面张力的变化 ,在室内将油井产出的含水原油与微生物混合后测定生成气体的组成 ,研究了微生物在油层生存繁殖及对原油的作用机理。现场试验见到了明显的增油效果。In order to improve reservoir recovery factor,microbiological production technology is developed.On the basis of the property of crude oil in Pucheng Oilfield,through simulation bottomhole condition is laboratory,the composition and physical characteristics of crude oil are determinated.The content of organic acid in associated water of crude and the variation of surface tension of water are presented.The paper studies the procreation principle of microorganism in reservoir and action on crude. Throrgh field test,the effictiveness of microbial enhanced oil recovery is obvious.
