本文根据双金刚烷的形成机理、各同分异构体之间的热演化关系以及西藏双湖地区Ｔ－Ｊ系烃源岩饱和烃组分中双金刚烷类化合物气相色谱－质谱实际检测结果，提出了５项双金刚烷指数，通过与Ｒｏ进行相关性分析，初步确定甲基双金刚烷指数ＭＤ１１可作为一种新的烃源岩成熟度参数应用。根据广西百色褐煤的（Ｒｏ＝０．４６％）热模拟实验，探讨了ＭＤ１１指数的热演化规律：ＭＤ１１指数与Ｒｏ具有良好的正相关性，相关系数为０．８３，作为有机质热成熟度指标，其应用范围在成熟和高成熟阶段。
Based on the formation mechanism of the bimamantane, the thermal evolution relationships among the isomers and the actual results of the double-adamantane GC-MS in the T-J hydrocarbon source rocks in the Shuanghu area, Tibet, , 5 biadamantane indices were proposed. According to the correlation analysis with Ro, it was preliminarily confirmed that the methyl-2-adamantane index MD11 could be used as a new maturity parameter of source rock. According to the thermal simulation experiment of Guangxi Baise brown coal (Ro = 0.46%), the thermal evolution of the MD11 index is discussed: the MD11 index has a good positive correlation with Ro, and the correlation coefficient is 0.83. , Its application in the mature and highly mature stage.
