【摘要】 本文利用气相色谱法对准噶尔盆地生油岩及原油中的芳烃进行了鉴定,并根据菲系列化合物的分布特征,对该盆地原油及生油岩成熟度作了分析,进而利用三环芳烃的指纹分布,追溯了西北缘石油的油源岩。结果表明,甲基菲是良好的成熟度指标;ββ型二甲基菲可用来研究原油的初次运移效应;而菲、甲基菲和二甲基菲各异构体相对百分含量分布曲线,则是良好的油/油和油/岩对比指标。更多还原

【Abstract】 Aromatic hydrocarbons in crude oil and source rocks from Junggar basin were identified by using gas chromatography.According to the distribution of phenanthrene homologue,this paper gives a discussion on the maturity of oil and rock samples,and then proceeds to make correlations between oils from northwest margin of the basin and their source rock by means of the fingerprints of tricyclic aromatic hydrocarbons.Preliminary evidence indicates that methylphenanthrenes are useful indicators for the maturity of oil and source rocks,and ββ bimethylphenanthrenes are of use for the study of pri- mary migration,while the relative percentage contents of phenanthrene, methylphenanthrenes and bimethylphenanthrenes are available for use in the correlations of oil/oil and oil/source rocks.更多还原
