摘　　要：通过对临清坳陷(东部)太原组低成熟煤系源岩加水热压模拟实验结果对比分析,发现生成的气态烃中二氧化碳的体积分数、甲烷体积分数、酸烷比及干燥系数在相同的温度点其数值差别明显,但具有相似的演化趋势;通过热模拟实验,结合研究区烃源岩特征,认为临清坳陷(东部)煤系源岩具备形成工业油气藏的物质基础。Through the comparative analysis of simulation experiment on low mature coal-measure source rock of Taiyuan Formation in Linqing Depression （eastern part） by adding hydro-thermal-pressure, it is found that the carbon dioxide content, methane content, acid alkane ratio and dry coefficient in the generated gaseous hydrocarbon are apparently different at the same temperature, but they have similar evolution trends. Through the thermal simulation experiment and combined with the characteristics of source rocks in the study area, it is considered that Linqing Depression （eastern part） has the material basis of industrial hydrocarbon reservoir.
