鄂尔多斯盆地石炭-二叠纪煤的生烃性能研究

Study on Hydrocarbon-generating Characteristics of Carboniferous Permian Coal in Ordos Basin

对鄂尔多斯盆地石炭-二叠纪煤进行深入的生烃性能研究,通过煤岩、煤质、热解试验结果,分析影响煤的生烃性能的主要因素,探讨各种技术参数间的相关关系。研究认为煤的生烃性与煤的有机质类型、镜质组含量、煤的变质程度等密切相关,煤型成烃母质为腐植型有机质,主要生成气态烃,是天然气的重要物源。

Through deepened study of Hydrocarbon generating characteristics of Carboniferous Permian coal in Ordos Basin and based on the results of coal petrological, coal quality and pyrolysis tests, the paper analysed the main factors influencing hydrocarbon - generating characteristics of coal, and discussed the relationship of different technical parameters. It is believed that the hydrocarbon-generating characteristics of coal are closely related to organic type, vitrinite content and rank of coal. Humic organic materials constitute hydrocarbon - grnerating source of coal mainly generate gasous hydrocarbon and are important material source of natural gas.
