Application of High Temperature Chromatography Technology to Study of the Source Rocks in Songliao Basin

Abstract

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
