摘要
通过野外剖面细测和钻井资料分析,揭示柴西阿尔金山前红沟子地区侏罗系地层中烃源岩分布特征,侏罗系地层有一定生油潜力,侏罗系大煤沟组地层可以作为生油层位。研究区浅部地层无有利的生、储、盖组合;下部地层存在非常规储层,具有较好的储集条件,侏罗系具有良好的生油岩,上部又具有较好的盖层条件,存在自生自储的组合关系。深部中侏罗统地层向上变粗的进积型扇三角洲,纵向上具有理想的生储盖组合。
According to the analysis of the geological profile and the drilling data,the distribution characteristics of Jurassic source rock,Qianhonggouzi area of Aljinshan in Caixi,has been revealed.The Jurassic formation has the resource potential.The Jurassic Dameigou formation can be regarded as the oil source layer.The upper layer has no good source-reservoir-seal assemblage.The unconventional reservoirs exists in the lower layer and have good reservoir conditions.The lower Jurassic layer has good source rocks and the upper layer has good seal conditions.They can form autogenetic and self-storing assemblage relationships.The lower Middle Jurassic is the progradational fan-delta facies,with coursing upwards,which has the excellent source-reservoir-seal assemblage vertically.
