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。
In this paper, the aromatics chromatographic analysis was carried out for the representative crude oil samples from continental China, and the aromatics compounds were confirmed on the aromatics chromatogram of crude oil. On the basis of this, the geochemical characteristics and applications of aromatics were discussed: (1) Methylnaphthalene , Methylphenanthrene and dimethylphenanthrene index can identify the maturity of crude oil; (2) the use of aromatics chromatography and its component distribution map can be compared crude; (3) the relative content of aromatic compounds, the difference between the land and sea Crude oil and so on. Aromatic compounds are more commonly found in continental oil, and from the aromatics chromatogram, a variety of geochemical information is available. This is a promising method.
