摘　　要：对比研究了山西沁水盆地李雅庄煤矿、寺河煤矿和附城七一煤矿煤岩的地球化学特征,讨论了煤岩的热演化程度、可溶有机质含量、生物标志化合物特征。在此基础上,分析了热成因煤层气与次生生物成因煤层气的气源潜力,对研究区煤层气勘探有实际意义。The geochemical characteristics of coals from Liyazhuang coal mine, Sihe coal mine and Fucheng coal mine of Qinshui Basin, Shanxi Province, were comparatively studied, and the thermal evolution degree, the contents of soluble organic matter and the biomarker characteristics of coals were discussed. Based on this, the potential of thermogenic and secondary biogenic coalbed gases were analyzed and it is of practical significance for the coalbed gas exploration in the studied area.
