摘　　要：济阳坳陷临南地区石炭—二叠系煤层分布广泛 ,其煤质优良 ,演化程度适中 ,具有形成中型煤型气藏的物质基础。该文从煤系地层烃源岩体描述、沉积埋藏及热演化史分析入手 ,通过有效生气中心确定、优势运聚方向分析、储盖组合研究及成藏后生演化的探讨 ,指出了研究区煤型气藏分布的主要控制因素 ,从而解释了近期钻探多种依据 ,并指明了下一步钻探的重点方向。The coal seam in Permocarboniferous system in Linnan area of Jiyang depression has the material base of forming middlescale coalrelated gas reservoir for its wide distribution, good quality and moderate evolution degree. It is started with the analysis on the source rocks description, sedimentary burial and thermal evolution history of coalmeasure strata in this paper. The master control factors of the distribution of the coalrelated gas reservoir in the study area are pointed out through the determination of effective gas generation center, the analysis of outstanding migrationaccumulation direction, the research of reservoircaprock assemblage and the discussion on epigenetic evolution of reservoirforming. Many foundations of recent explorationdrilling are then interpreted and the next major explorationdrilling direction is pointed out.
