【摘要】 用有机地球化学方法研究贵州中西部地区煤岩的生烃机理和生烃模式。石英小玻管热模拟实验和红外光谱对贵州盘县晚二叠世煤的分析表明,盘县煤的干酪根类型为Ⅲ型,主要成分是均质镜质体和丝质半丝质体,主要生成物是短链烃,显著生烃的起始温度约为300～350℃。更多还原

【Abstract】 Organic geo-chemical methods were utilized to simulate the hydrocarbon-generation modes of coal samples from Guizhou Province.High temperature simulation experiment by quartz cuvette technique and microscope analysis by FTIR were utilized to estimate hydrocarbon-generation mode and potential of local coal mine in Panxian,Guizhou Province.The results indicate that,the kerogen of Panxian coals is of Ⅲ type;the heating product is mainly gas because of the simple component of kerogen;and the mass hydrocarbon producing temperature is about 300-350℃.更多还原
