摘要

在红山断陷内钻井及周边露头剖面中侏罗统烃源岩系统分析的基础上,通过对其有机质丰度和类型、烃类化合物的组成及其成烃演化阶段进行全面分析与评价,认为:红山断陷中侏罗统主要的烃源岩类型为泥岩和油页岩,有机质沉积于淡水环境,其中油页岩属Ⅱ型,泥岩、炭质泥岩和煤多属于Ⅲ1—Ⅲ2型。红山断陷地表剖面的中侏罗统烃源岩主要处在未熟—低熟阶段,地下中侏罗统烃源岩也主要处在未熟—低熟阶段,少量处于成熟阶段。总体来看,红山断陷中侏罗统具备一定的资源潜力,是值得重视的一个勘探区。

Abstract

This article based on the drilling in Hongshan sag and the systemic analysis of middle Jurassic hydrocarbon source rocks surrounding outcrop profile,the abundance of organic matter and types,the composition of the hydrocarbons and evolutional stages of alkylation were comprehensive analsed and evaluated,the analysis shows that the major type of middle Jurassic hydrocarbon source rock is mudstone and oil shale in Hongshan sag,the organic matter deposits in fresh water environment,there into oil shale is Ⅱ,shale,carbonaceous mudstone and coal are mostly Ⅲ1-Ⅲ2.The most of middle Jurassic hydrocarbon source rocks in the surface profile of Hongshan sag belong to unbaked to low maturity,the underground middle Jurassic hydrocarbon source rocks also mainly belong to unbaked to low maturity,and a little of the organic matter belongs to maturity.Overall middle Jurassic of Hongshan sag has certain resource potential,which is an appreciable exploration area.
