EFFECT OF PORE STRUCTURE ON CBM TRANSPORT --TAKING QINSHUI BASIN AS THE EXAMPLE
孔隙结构在煤层气运移过程中的作用――以沁水盆地为

Through a large amount of basic research, this paper discusses the restrict relationship and degree of dual-porosity media system of coal reservoir acting on diffusion and transport of CBM. Taking Qinshui basin as the example, the different effects of pore system and fracture system on process of CBM transport are investigated, and some conclusions are obtained.
