【摘要】 通过对平顶山、郑州和南票3大矿区石炭二叠纪含煤岩系中高煤级烟煤和无烟煤的热解成烃潜力分析,探讨了构造煤热解产烃潜力与原生结构煤的不同演化特征及其影响因素。结果表明,构造应力,尤其是剪切应力对煤大分子聚合物的侧链及官能团,具有一定的降解能力,促进了成烃的演化速率。更多还原

【Abstract】 Through Rock-Eval analysis of Carboniferous-Permian bituminous coal and anthracite in Pingdingshan mine, Zhengzhou mine and Nanpiao mine, the evolution character of pyrogenation hydrocarbon generating potential of deformed coal and undeformed coal and their effecting factors are studied. As a result, it is showed that the tectonic stress, especially shear stress, results in degradation of side chains and functional groups of coal large molecules polymer, and accelerating evolution of hydrocarbon generation.更多还原
