摘要：

本文通过对冀中坳陷霸县凹陷岔河集油田渐新统东营组和沙河街组几层具有相同来源的原油的分析对比,探讨了运移对甾烷、萜烷类生物标志物分布特征的影响。研究结果表明,C21—C22低碳数甾烷、重排甾烷、甾烷ααα-20S异构体和αββ—(20R+20S)异构体的相对丰度,以及三环萜烷的相对丰度,均随运移而增加。在确定油源和母岩成熟度以后,这些生物标志物相对丰度可以作为运移指标。

Abstract:

The authors studied the biomarkers in Oligocene crude oil and source rocks ofChaheji oilfield ln Hebei Province, and found out that the values or the para-maters such as C21+22 sterane/C27+28+29 sterane, ααα-20S-C29 sterane/ααα-(20R+20S)-C29 sterane, αββ-(20R+20S)-C29 sterane/ΣC29 sterane, rearranged sterane/regular sterane and tricyclic terpane/pentacyclic terpane increase as the migration distance increases.
