【摘要】 通过对国内外有关煤变质作用与煤层气形成、赋存和富集关系研究成果的系统总结,阐述了煤变质作用类型及煤变质作用程度与煤层气的生成、吸附量、煤储层孔隙-裂隙系统形成发育及煤层特性的相互关系,认为煤变质作用对煤层气赋存富集的影响集中体现在它对煤储层孔隙-裂隙系统形成发育过程的控制上。并以沁水盆地为例,探讨了高阶煤煤变质作用对煤层气赋存富集的控制作用,提出了对沁水盆地高阶煤煤层气勘探开发研究的几点思考和建议。更多还原

【Abstract】 By reviewing the current achievements in the studies of relationships between coal metamorphism,distribution and accumulation of the coalbed methane,we find that different types and degrees of coal metamorphism have different effects on the formation,transportation, and accumulation of coalbed methane.Mainly through affecting the formation and evolution of pore and track system in the coal seams,coal metamorphism is one of the most important geological factors which control the distribution and accumulation of coalbed methane.With the Qinshui Basin as a case,we discussed how the metamorphism of high-rank coal controls the formation and accumulations of the coalbed methane,and proposed some suggestions for the exploration and development of the coalbed methane in this coal field.更多还原
