| 摘 要： | 通过喜氧细菌对原油的模拟生物降解实验,以及对模拟产物的饱和烃色谱—质谱分析,对原油饱和烃中规则甾烷和重排甾烷的降解作用进行了研究。研究结果显示,规则甾烷先于重排甾烷发生生物降解,甾烷降解由易到难的顺序为C27>C28>C29。在甾烷被大量降解前,20S/(20S+20R)(甾烷异构化作用)等生物标记化合物的成熟度指标基本无变化,但某些用于油源对比、母源和沉积环境研究的生物标记化合物参数可能会发生变化,如:规则甾烷/17α(H)-藿烷、C27-C28-C29甾烷、C27-C28-C29重排甾烷和重排甾烷/规则甾烷等。

| Abstract: | The biodegradation of regular sterane and rearranged sterane in crude oil was studied on the basis of simulated biodegradation experiment to the crude oil.The biodegradation products were analyzed by GC-MS.Research shows that the biodegradation of regular sterane is early than that of rearranged sterane.The biodegradation ability of sterane is C27>C28>C29.Before the great biodegradation of the sterane,those maturity indicators such as isomerization of C29 steranes at C20 vary slightly.But some biomarker indicators used for the researches on oil-source correlation,oil source and sedimental environment will probably change.These indicators include ratio of regular steran to 17α(H)-hopane,C27-C28-C29 sterane,C27-C28-C29 rearranged sterane,ratio of rearranged sterane to regular sterane,and so on. |
