摘要

中—上元古界具有最古老而又未变质的沉积层系,其原生油气是一个值得关注的能源资源领域。华北地区中—晚元古代地层分布广,厚度大,地层时代老,张家口下花园青白口系下马岭组是我国华北地区从元古界到下古生界海相沉积有机质相对富集的沉积层段。为了深入研究下马岭组烃源岩的分子指纹特征,对华北中元古界下马岭组海相低熟灰质泥页岩进行了沥青质抽提、GC-MS分析。样品饱和烃的GC-MS分析数据显示,烃源岩的沉积环境为微咸化浅海/滨海相还原环境,母质输入以原核生物为主,演化程度低,未检出甾烷。表明前寒武纪地层是以原核生物为主要有机质物源的沉积岩,在一定的条件下,也可以成为好的烃源岩,具有良好的原生油气资源前景。

Abstract

Meso-Neoproterozoic had the most ancient and unmetamorphosed sedimentary strata,and its primary oil and gas were a notable field of energy resources.The Xiamaling Formation from Proterozoic to Paleozoic was widely distributed with relative enrichment of marine organic matter in North China.In order to understand the molecular fingerprint feature of the source rocks,GC-MS analyses were performed.Alkanes,isoprenoids,hopanes,alkylcyclohexanes,alkylmethylcyclohexanes and so on have been found in the Precambrian rocks which are 1 400-1 320 Ma old.The indicators of saturated hydrocarbon showed that the depositional environment of source rocks was reductive shallow sea.The input of precursor was dominated by prokaryote organisms,and steranes were not detected.The results suggest that the Precambrian rocks with prokaryote organisms can also be good source rocks,with good prospects for primary oil and gas resources.
