摘　　要：产表面活性剂菌在微生物采油特别是稠油微生物开采领域起着重要作用。通过稠油微生物乳化降粘试验,筛选培养出高效、广谱的产表面活性剂菌种(WS-SPB);分析了影响WS-SPB生长的因素,初步得出其最佳生长条件;进行了WS-SPB稠油乳化降粘试验研究,评价其稠油降粘效果;对其现场应用潜力进行分析,对进一步优化培养优良产表面活性剂菌菌种提出了建议。Surfactant producing bacteria plays an important role in microbial enhanced oil recovery,especially in the field of viscous oil exploitation by bacteria.By the experiment of emulsifying and deviscousing to viscous oil by bacteria,we have selected and fostered the high and extensive efficiency surfactant producing bacteria(WS-SPB);have analyzed the factors which affect the growing of WS-SPB,initially obtained its best conditions of growth;have run the experimental study of emulsifying and visbreaking viscous oil,and evaluated its effects of visbreaking viscous oil;at last,we have analyzed its applying potential capacity in field,and proposed how to further optimize and foster the excellent surfactant producing bacteria.
