摘要
煤中裂隙是煤层气主要渗流通道。基于郑庄-樊庄区块煤的内生裂隙与煤的变质程度、显微组分、煤岩类型煤相环境指标的相关性关系,分析煤岩学特征对内生裂隙的影响。结果表明,煤中内生裂隙的发育受煤岩学特征影响强烈。
Fractures in coal are the main seepage channels of coalbed methane. Based on the correlation between the endogenetic fracture of the block coal in Zhengzhuang-Fanzhuang block and the metamorphism degree, macerals and coal facies environmental indexes of the coal rock type,analyzes the influence of the coal petrological characteristics on the endogenetic fracture. The results show that the development of endogenetic fractures in coal is strongly influenced by the characteristics of coal petrology.
