摘　　要：为研究微生物降粘技术在海外河油田增油增液的效果,通过分析微生物采油技术降粘的原理,选取海外河油田六口井进行室内实验研究,分别对微生物菌种的筛选、菌群配伍性、耐矿化度性、耐温性及耐酸性等开展实验研究,筛选出适合海外河油田应用的,具有较好的配伍性、耐矿化度性、耐温性及耐酸性等性能较为稳定的微生物制剂。通过现场矿场试验微生物采油措施,有增油、增液效果,说明注入地层中的微生物起到了降低原油粘度的作用,使原油更易流入井底。Microbial oil production is a certain kind of pattern using the natural microorganisms for recovery, under the certain conditions, through metabolism to improve the crude oil recovery. By analyzing the principle of MEOR visbreaking, we made experiments in lab to research the six wells in Haiwaihe oilfield, respectively for screening, compatibility, resistance to salinity, temperature resistance and acid resistance experiments of microbial bacteria, screened for microbial preparation in Haiwaihe oil field application. Through field test, it is proved that microbial oil recovery technology can improve the productivity of measure well.
