In order to reveal the coalbed methane(CBM) productivity differences of typical blocks in Qinshui Basin, this study utilized the methods of theoretical analysis and numerical simulation to research coalbed methane reservoir characteristics and its effect on productivity of the typical block in Qinshui Basin. Based on CBM well production data, the study identified the productivity differences, and analyzed the main control factors that impact the CBM well productivity. The key parameters including the target coal seam resource abundance, permeability, critical desorption pressure are proposed to evaluate productivity. The results of study show that the southern Qinshui Basin coalbed methane resources are more recoverable than that of the north, a typical block exploitation prospect of CBM in ranking for Pan Zhuang, Daning, Shouyang, Gujiao.
