摘　　要：在济阳坳陷中生界古潜山油气储集系统、构造对油气成藏的控制作用等分析基础上,对油气富集规律分析认为,古潜山圈闭油气富集高产必须邻近古近系生油凹陷且位于油气运移通道系统之上、发育构造裂缝及次生孔隙的砂砾岩或火山岩储集系统、具有古近系的区域性披盖层;综合生、储、盖和构造条件分析,对中生界古潜山油藏有利勘探区带进行了预测,对下一步深层油气勘探具有一定的指导意义。Analysis of the controlling effect of reservoir system and structure on hydrocarbon accumulation in Mesozoic buried hill of Jiyang Depression indicates that buried hill traps yielding high production must be near Paleogene hydrocarbon kitchen and located on migration pathway system,be glutenite or volcanic reservoir system with structural fractures and secondary porosity,and have Paleogene regional drape caprock.Favorable exploration areas of Mesozoic buried hill reservoir have been predicted based on comprehensive analysis of source-reservoir-cap and tectonic conditions.This study provides guidance to deep oil and gas exploration in the future.
