摘要
华北地区中上元古界生油岩及热模拟实验表明,在有机质热演化的三个阶段中,正、异构烷烃在主峰碳位置,Pr/nC_(17)与Ph/nC_(18)值等方面具有不同特征。本文重点揭示了过成熟阶段正、异构烷烃特征的某些“逆反”现象。
A thermal simulating experiment on the samples from the middleupper proterozoic source rocks in North China has shown that in the three stages of thermal evolution of organic matter nor- and iso-alkanes show some differences in main carbon peak, Pr/nC17 and Ph/wC18. In this paper emphasis is placed on the reversibility of the characteristics of nor- and iso-alkanes at the stage of over maturation of organic matter.
