摘要: 随着石油地球化学研究的深入和现代分析测试技术的发展,生物标志化合物参数越来越多。在已有明确地球化学意义的参数基础上,选用南阳凹陷 27 个原油生物标志化合物分析的 30 个油气地球化学指标,运用灰色关联分析方法,对现有指标的地球化学意义作出评价,归纳为反映有机质生源特征的、衡量有机质热演化成熟度的以及两者兼有的 3 种类型,并遴选出 m(β锥满烷)/m(α+β锥满烷)、m(βα娠甾烷)/m(αβ娠甾烷)、m(奥利烷)/m(γ-蜡烷)、m (8, 14–断藿烷 C29)/m(C30)等新的油气地球化学指标,对油气地球化学深入研究有一定意义。

Abstract: With the development of petroleum geochemistry and improvement of modern analytical technology, more and more biomarker parameters of petroleum are available.This paper selects 30 biomarker indices from 27 oil samples in Nanyang depression on the basis of some well known biomarker indicators and using the grey correlation analysis, and classified into three types related to original organic matter, organic matter maturity and both of them.Such new geochemical indices as m(β-drimane)/m(α+β-drimane),m(βα-pregnane)/m(αβ-pregnane), m(oleanane)/m(gammacerane), m(8,14-secohopane C29)/m(C30) are proposed in this paper.They will support the in-depth study of the molecular parameters in geochemistry.

Key words: molecular biomarkers, biomarker parameters, grey correlation analysis, Nanyang depression
