摘　　要：根据对燕山地区地层结构和岩石组成的分析,确定了以洪水庄组、铁岭组暗色泥、页岩(生)—雾迷山组白云岩(储)—洪水庄组泥、页岩(盖),以及铁岭组、下马岭组暗色泥、页岩(生)—铁岭组白云岩(储)—下马岭组泥、页岩(盖)为主的两套生储盖组合。对泥、页岩生烃指标进行了分析,确定了洪水庄组和下马岭组泥、页岩为主的两套烃源岩。结合地质演化过程的分析,认为燕山地区中、上元古界具有很好的含油气远景。Based on the analysis of stratigraphic structure and rock constituents of the Yanshan area, the two source-reservoir-cap rock associations are determined. The one is composed of dark mud and shale of the Tieling and Xiamaling formations (hydrocarbon generating), dolomite of the Wumishan Formation (reservoir), and mudstone and shale of the Hongshuizhuang Formation (cap). The other is made up of dark mudstone and shale of the Tieling Formation (source), dolomite of the Tieling Formaton (reservoir), and mudstone and shale of the Xiamaling Formation (cap). Based on the analysis of indicators of source rock of mudstone and shale, two suites of hydrocarbon source rocks consisting chiefly of mudstone and shale of the Hongshuizhuang and Xiamaling formations and determined combined what the analysis of geologic development process, it is regarded that the oil and gas of the Yanshan area may be well preserved and that the old anticline and drape structure of the superimposition of rock strata is place advantageous fo oil and gas reservoirs. The Middle and Upper Proterozoic of the Yanshan area have significant hydrocarbon potential.
