The south Qinshui basin is one of the most hot areas in the coalbed methane (CBM) exploitation and the first commercial exploitation of CBM in China. No 3 and No 15 coal seams is the developed seam of CBM, with gas production of 2 000~5 000 m3/d for single well. The permeability is generally about 1.0×10-3μm2 by input or drawdown test. Base on data of CBM production in different blocks, the permeability of coal seam is amended by historical matching of numerical simulation. The amended permeability is in range of (0.47~3.95)×10-3μm2, which is about 6.76 times than that of well test. The positive relationship between CBM production and amended permeability of coal seam exists. The permeability of coal seam in the south of Qinshui basin is high, especially at the Panzhuang and Duanshi areas.
Key words： Production data; Permeability; Historical matching; Well test.
