摘要

作者用红外光谱仪分析了泌阳凹陷生油岩干酪根

研究了干酪根中烷基、含氧官能团和芳环的变化规律。含氧官能团随埋深逐渐减少

到达一定深度后完全消失;烷基具有明显的高峰区

这个高峰与生油高峰是一致的;芳环在生油门限前后比较稳定

生油高峰过后明显增加。

Abstract

The authors studied 41 samples of kerogen from the Eogene HetaoyuanFormation in Biyang Depression

Henan by ETIR technique.Oxygen-bearingfunctional group decreases with the increase of buried depth

and completelydisappeared at 3500m.Alkyl group increases to a peak value with theincrease of buried depth

and then decreases gradually.The depth of peak-value shows identity with that of oil-generating peak.Aromatic rings showa little change near the threshold depth of oil-generation but increases obvi-ously below the depth of oil-generation peak.
