| 摘 要： | 在好氧及厌氧实验条件下发现,烃氧化菌和硫酸盐还原菌(SRB)的混合菌可以直接消耗原油,使原油的组分发生变化。对经微生物处理后的原油进行了气相色谱分析,结果表明:烃氧化菌可以降解原油,使轻组分相对减少、重组分相对增加;硫酸盐还原菌在厌氧条件下也可以降解原油,但与前者的结果是有差别的。在塔里木盆地一些油气藏的地层水中检测到的硫酸盐还原菌的含量高达104个/ml,支持了这些油气藏中的H2S为生物成因的观点。 |

| Abstract: | In the aerobic condition, the structure of crude oils were changed by hydrocarbon-oxidizing bacteria. The structure of crude oils was also changed by sulphate-reducing bacteria in the anaerobic condition. Sulphate-reducing bacteria can make use of crude oils as sole carbon source. After treatment of crude oils, the sample was analyzed with gas chromatograph(GC).The result of GC show the lighter compounds of crude oils decrease, but the more high weight compounds increase. The sulfate-reducing bacteria were detected in the oilfield water of Tarim basin. Its numbers were up to 10~(4) cells/ml. The results support the view that H_(2)S is the origin of biology. |
| Keywords: | Anaerobic bacteria Sulphate-reducing bacteria Model test Crude oil H_(2)S. |
