摘要
阜阳地区石炭-二叠系煤系地层发育，但由于勘探程度较低，对该区煤系地层烃源岩的生烃潜力认识不清，严重制约了该区的油气勘探。在已有资料的基础上，通过有机地球化学和有机岩石学方法并结合模拟实验，探讨了该区煤系烃源岩的生烃潜力。研究结果表明阜阳地区石炭-二叠系煤系烃源岩有机质丰度达到中等-好烃源岩标准，有机质类型以腐殖型为主，盆地模拟结果显示阜阳地区石炭-二叠系煤系地层油资源量为（30．47～152．33）×10^6t，气资源量为（266．7～1333．7）×10^8m^3，展示阜阳地区石炭-二叠系煤系地层具有较好的生油气潜力。
The Permo-Carboniferous coal measure formations are highly developed in Fuyang area. However, understanding of the hydrocarbon generating potentials of the source rocks in these coal measure formations is poor due to the low maturity of exploration, thus exploration in this area is severely constraint. Based on the available data, this paper discusses the hydrocarbon generating potentials of the coal measure formations in the study area, through integrating organic geochemistry with organic petrology and in combination with simulation experiments. The study results show that the organic matter abundance in the study area reaches the standards of moderate-good source rocks and the organic matters are mainly of type Ⅲ. Basin modeling shows that the oil and gas resources in the study area are estimated to be in the range from 30.47 to 152.33 million tons and from 26.67 to 133.37 billion cubic meters, respectively, indicating the relatively high hydrocarbon generating potentials of the Permo-Carboniferous coal measure formations in Fuyang area.
