【摘要】 本文对我国陆相代表性原油样品,进行了芳烃色谱分析,并对原油芳烃色谱图中的芳烃化合物进行了确认,在此基础上探讨了芳烃的地球化学特征及应用:(1)甲基萘、甲基菲及二甲基菲等指数可以识别原油的成熟度;(2)应用芳烃色谱及其组分分布图可以进行原油对比;(3)应用芳烃化合物的相对含量的差异,区别海陆相原油等。陆相原油中较普遍存在着芳烃化合物,而从芳烃色谱图中,可获得多种地球化学信息。这是一种有应用前途的方法。更多还原

【Abstract】 Representative aromatics samples of terrestrial crude oil of our country have been analysed by gas chromatography and aromatic peaks of crude oil have been identified in this paper,Based on this observation,geochemical characteristics and applications of aromatics have been studied.(1) The methylnaphthalene,the methylphenanthrene and the dimethylphenanthrene index can identify maturity of crude oil.(2) Aromatic gas chromatogram and (?)istribution patter can be used as fingerprints for oil-oil correlation.(3)Using the differnces of the relative content of aromatics can identify terrestrial or marine crude oil et al.Because aromatic hydrocarbones are generally present in terrestrial crude oil,more information about petroleum geochemistry can be obtained from aromatic GC,so it is a me- thod having prospects.更多还原
