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Ⅲ1—Ⅲ2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。
Based on the systematic analysis of the Middle Jurassic source rocks in the drilling and peripheral outcrop sections of the Hongshan fault depression and through comprehensive analysis and evaluation of the abundances and types of organic matter, the composition of hydrocarbon compounds and the stage of hydrocarbon generation and evolution, It is concluded that the main source rocks of the Middle Jurassic in the Hongshan faulted depression are mudstone and oil shale, and the organic matter is deposited in the freshwater environment. Type Ⅱ, mudstone, carbonaceous mudstone and coal belong to Ⅲ1-Ⅲ2 type . The middle Jurassic source rocks in the surface section of Hongshan fault depression are mainly in the immature-low maturity stage, and the underground Middle Jurassic hydrocarbon source rocks are also mainly in the immature-low maturity stage, while a small number are in the mature stage. Overall, the Middle Jurassic in the Hongshan faulted depression has certain resource potential and is an exploration area worthy of attention.
