Abstract: The margin of the southern Qinshui Basin is confined by faulted fold belts，the enrichment region is formed in gentle slope area.By the affection of regional tectonicthermal evolution，the coal reservoirs have undergone the plutonic metamorphism，tectonicdynamic metamorphism and magmatic thermal metamorphism，and they were caused into different degrees of metamorphic and deformation.The reservoirs possess different characteristics in many aspects of physical properties，such as metamorphic and deformation，gas bearing capacity and permeability.They show obvious regional differentiation and form three NENNE structural regions of coalbed methane pool，which have the same spreading direction with the direction of synclinorium spindle and magma intrusion in Yanshan period.The structural regions are Zaoyuanfanzhuang region(TREND1)，Sidichengzhuang region(TREND2)and Zhengzhuang region(TREND3).Their gas content and permeability possess obvious distribution in EW and SN.From east to west，the gas content and permeability in TREND1，TREND2 and TREND3 reduce one by one.From south to north，the TREND1 can also be divided into three parts：Panzhuang block(1A)，Zaoyuan block and Hudipichi block(1B)and Fanzhuang block(1C).The gas content and permeability is best in 1A，medium in1B，low in 1C.
