摘要：

本文用数理统计方法对21项生物标记物指标进行了初步筛选。基础数据主要是我国6个盆地192个生油岩样品的数据。C27规则甾烷/C29规则甾烷是反映干酪根类型的较好指标。αβ升藿烷系列22S/22R、(降)藿烷/(降)莫烷、αααC29甾烷20S/(20R+20S)是反映生油岩成熟度的较好指标。某些生物标记物指标没有明显的实用价值。

Abstract:

Based on the statistical analysis of the geochemical data of more than 192 rock samples collected from 6 basins in China,the author has come to the following conclusions:1.The parameters 17α21β-Hopane-22S/22R,17α21β-Hopane/17β21α-Moretane and 5α14α17αC29-Sterane-20S/(20R+20S)are available maturity indices of source rocks.2.The sterane ratio 5α14α17αC27/5α14α17αC29 is a better index of kerogen types.3.Some parameters,as Pristane/n-C17,Phytane/n-C18,are of little practical value.
