为了研究济阳坳陷石炭–二叠纪煤系泥页岩生烃潜力，应用地球化学、石油地质学及煤地质学等方法，从济阳坳陷石炭–二叠系残留地层分布、泥页岩有机地球化学特征和泥页岩生烃潜力对比等方面进行研究。研究结果表明：济阳坳陷石炭–二叠系残余地层厚度一般在200~800 m，最厚可达900 m；煤系泥页岩有机质丰度较好，为Ⅲ型干酪根，有利于生气，有机质成熟度达到成熟–较高成熟阶段；本溪组和太原组生烃潜力较好；山西组烃源岩各凹陷均可见中–好油气源岩，但范围局限，整体评价仍为中等。与我国其他地区对比发现，济阳坳陷石炭–二叠系煤系泥页岩生烃能力总体处于中等水平，具有一定的页岩气勘探潜力。

In order to study the hydrocarbon potential of mud shale of Permo-Carboniferous coal-bearing measures in Jiyang depression, distribution of residual stratum, organic geochemical characteristics of mud shale and hydro-carbon generation potential comparison of mud shale of Permo-Carboniferous in Jiyang depression were studied in this paper with the methods of geochemistry, petroleum geology and coal geology. The results showed that residual stratum of Permo-Carboniferous in Jiyang depression was thicker in the south than in the north and distributed in large expanse. The residual thickness could generally reach to 200~800m, the thickest could reach to 900m. Abundance of organic matter of shale was better. Kerogen was of type III and conducive to generate gas. Maturity of organic matter reached to mature-higher mature stage. Hydrocarbon potential of Benxi Formation and Taiyuan Formation was better and mainly distributed in northern basin. Hydrocarbon potential in Dongying, Huimin, Chezhen and Zhanhua got bet-ter in turn. There were medium-good quality oil and gas source rocks in each sunken of hydrocarbon source rocks of Shanxi Formation. Comparing the characteristics of the clay shale in the study area with those in other regions in China, hydrocarbon generation ability of coal shale of Permo-Carboniferous coal beaaring-measures in Jiyang depres-sion is of the medium level. There is certain shale gas exploration potential.
