| 摘 要： | 通过对胜利油田四个正常原油样品微生物作用前后的族组分及饱和烃色谱质谱分析,发现实验室条件下微生物对原油有明显的降解作用。微生物作用以后的原油族组分其饱和烃相对含量降低,饱/芳比也明显降低,而芳烃、非烃和沥青质的相对含量都不同程度的升高。通过饱和烃色谱-质谱分析,发现微生物作用以后原油正构烷烃被严重降解,姥/植(Pr/Ph)比值和∑C21-/∑C22+比值都明显降低。微生物作用原油后能产生表面活性剂,造成了培养基表面张力的降低。

| Abstract: | Based on the analyses of the four crude oil samp les in Shengli oil fields, it is found that microbe can degradate the crude oil in laboratory. After the microbe degradation, the crude oil samp les have low saturated hydrocarbon contents and low saturated hydrocarbon / aromatic hydrocarbon ratios, and high aromatic hydrocarbon, non-hydrocarbon and asphaltene. It also shows that the normal paraffin hydrocarbon of crude oil has a deep degradation aftermicrobe degradation, and a low Pr /Ph value and a low ΣC21 - /ΣC22 + ratio. After the action of microorganisms on crude oil, some surface-active substances produced, and caused low surface tension. |
