摘　　要：对俄罗斯西伯利亚南部原油中的细菌进行分离和培养,确定了原油中的细菌种类;将培养的微生物配制成溶液,进行模拟环境的钢铁挂片试验,并与原油钢铁挂片试验的试验结果进行对比。配制溶液中钢片腐蚀明显,而原油中因基本不含水,试片很少变化。The kinds of microbes separated from the crude oil of south Siberian of Russia were determined, Those microbes were cultivated and put into solutions. Some steel specimens were tested in the solution and in the crude oil under the same conditions for about 6 month. The corrosive behavior of microbes was compared and analyzed by observation of the corrosion characteristics on the surface of steel specimens. The steel specimens were markedly corroded in the solutions with microbes.
