摘要：

本文以济阳坳陷39个原油样和29个生油岩样的30项生物标志物指标实测值为基础数据,用广义对应分析法对这些指标进行了筛选。5α-C27甾烷的ββ/(αα+ββ)和5α-C29甾烷的20S/(20R+20S)是反映原油成熟度的主要指标,重排甾烷相对丰度、4-甲基甾烷相对丰度和Tm/Ts是原油成熟度的辅助指标。

Abstract:

Based on the data of 30 biomarker indices of 39 crude oil samples and 29 source rock samples collected in the Jiyang Depression,Huabei Basin, the author screened these indices by generalized correspondence analysis. It is suggested that the 5α-C27 Sterane ββ/(αα+ββ) and 5α-C29 Sterane 20S/(20R+20S)are the main indices of crude oil maturity, while the relative abundance of rearranged Sterane, 4-methylsterane and Tm/Ts are of secondary importance.
