摘　　要：针对试验区油藏地质情况,从室内保藏菌种筛选出降解原油性能突出菌、产酸性能突出菌和产生物表面活性剂性能突出菌等不同驱油菌种;模拟试验区油藏条件,进行了室内微生物驱油试验,考察了不同功能菌种的驱油效率,菌种和营养剂不同注入方式的驱油效率,不同菌剂段塞质量分数的驱油效率,菌种在岩心中不同发酵时间对驱油效率的影响,菌种产气量与驱油效率的关系等。In view of the candidate reservoir geological conditions in pilot area of Karamay field, several bacteria species are screened from MEOR lab for hydrocarbon degradation, which have properties of producing the acids and the bio-surfactant, etc. The reservoir geological conditions in pilot area are simulated and the experiment for lab microbiological oil displacement is made, in order to detect the oil-displacing efficiency for such bacteria species in function, injection period and plug concentration, and their effect on the efficiency in different fermentation time as well as the relationship between gas volume produced by the bacteria species and corresponding oil-displacing efficiency.
