摘　　要：研究了两株假单胞菌K80-A、K80-B对大港油田官69原油的作用效果。实验证明,能产生乳化因子和假溶因子的K80-B菌株对原油粘度的降低率为51.6％、凝固点降低2℃;而只产生表面活性剂的K80-A菌株对同一原油的作用效果分别为43.5％和3℃。当两菌株以等比例混合共同作用原油时,以上指标均有明显提高。说明两菌株具有协同效应。矿场试验证明了混合菌种的优势。Two Pseudomonas strains, K80 - B and K80 - A, can use hydrocarbon as carbon source by two different mechanisms. Different effects can be observed when they are applied to 69-8 oil of Dagan Oil Field. The strain K80-B producing both hydrocarbon pseudosolubilizing factor and hydrocarbon emulsifying factor can decrease the viscosity and solidifying point of the 69-8 oil 51.6% and 2℃ respectively. Whereas the other can only decrease 43.5% and 3℃ respectively. When the two strains are mixed, synergistic effect on crude oil is obvious.
