作者以抚顺、茂名、黄县油页岩干酪根和黄县褐煤有机质为试样,采用差示扫描量热法(DSC).对干酪根的热演化进行研究,并根据干酪根结构参数的变化,讨论其母质类型及油气生成潜力.

In order to study thermodegration of kerogen,the samples of kerogen in oil shales from Fushun,Maoming and Huang Xian and organic matter of brown coal from Huang Xian were investigated with differential scanning colorimetry(DSC) technique. The relations between the types of parent materials and oil-gas generating patential were discussed based on the parameter variation of kerogen structures. There are two peaks in all DSC curves for all types of kerogens, which are combustion peaks of carbon aliphaticity and carbon aromaticity respectively. The areas of the two peaks can be used to calculate carbon aliphaticity and carbon aromaticity of structure parameters of kerogen. These two parameters are related to the types and maturity of kerogen, and to a certain extent, they may represent potential of oil and gas generation for kerogen.
