摘　　要：目的利用不同驱油功能菌株构建有效复合驱油菌系。方法对不同组合的驱油菌系分别进行石油降解实验、乳化实验、表面张力测定以及岩心驱替实验等。结果通过实验得到一组复合驱油菌系,在岩心驱替实验中将采收率提高了9.6%。结论通过实验构建复合驱油菌系,得到其最佳配比以及最佳菌种比例,可有效提高石油采收率。Objective To construct effective oil displacement system by using bacterial strains with different oil displacing functions.Methods Oil degradation experiments,emulsifying experiments,surface tension measurements and core displacement experiments were performed on different combinations of oil displacement systems.Results A compound displacement system was obtained,and the recovery efficiency of which was increased by 9.6%in the core displacement experiment.Conclusion A bacterial oil displacement system with optimal combination and proportion was built,which can effectively improve the oil recovery rate.
