Abstract: Based on the analysis of the production dynamics of coalbed methane wells in the Fukang mining area, in combination with the production characteristics of gas wells in each coal seam, three types of coalbed methane production models were established in the Fukang mining area and subdivided into six subcategories.The key researches on the geological and engineering factors that affect the coalbed methane production in the Fukang mining area have been conducted.Findings are that:in geological factors, the coalbed methane production is proportional to the depth of the coal seam, and the greater the depth, the greater the yield; the gas production is inversely proportional to the thickness of the coal seam, and the analysis considers that it is related to the heterogeneity and perforation range of the coal seam; ; among the engineering factors, multiple layers are combined and the inter-layer interference is serious; the gas production volume is proportional to the fracturing output, and the larger the output, the better the production capacity.
