【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。更多还原

【Abstract】 Based on the statistical analysis of the geochemical data of more than 192rock samples collected from 6 basins in China,the author has come to the fol-lowing conclusions:1.The parameters 17α21β-Hopane-22S/22R,17α21β-Hopane/17β21α-More-tane and 5α14α17αC₂₉-Sterane-20S/（20R+20S）are available maturity indicesof source rocks.2.The sterane ratio 5α14α17αC₂₇/5α14α17αC₂₉ is a better index of kerogentypes.3.Some parameters,as Pristane/n-C₁₇,Phytane/n-C₁₈,are of little prac-tical value.更多还原
