摘要: 选择了烃源岩和原油中高分子量烃类的富集和高温色谱分析方法,可将松辽盆地北部原油中烃类检测的最高碳数从C40提高到C100通过对英15井不同层位烃源岩和英16井黑帝庙油层原油全烃高温色谱分析和地球化学特征对比研究发现,嫩二段、嫩一段烃源岩地化特征类似,嫩江组与青一段烃源岩地化特征差异明显;英16井黑帝庙油层.原油主要来自嫩江组烃源岩。高温色谱分析为油源关系、油气成因、稠油研究等提供了新方法。

Abstract: By using high temperature chromatography tool for medium-high molecular weight hydrocarbons abundance in crude oil and source rock, the carbon numbers from Co to Cr of hydrocarbons in crude oil in northern Songliao basin could be detected. It is suggested from correla-tion and study of Ying-15 Well for different horizons of source rocks and Ying-16 Well for Heidimiao formation hydrocarbons by this tool that similar geochemical features are found in Nen-1 and Nen-2 members,and clear difference of source geochemical feature occur between Nen-jiang formation and Qing-1 member. Crude oil from Heidimiao formation in Ying-16 W ell is mostly originated in Nenjiang source rocks. High temperature chromatography as a new tool for the researches of crude oil correlation, oil-gas origin and heavy oils can be applied.

Key words: crude oil, source rock, molecular weight, chromatography analysis, source correlation
