摘　　要：简要分析煤层气的排采机理,并将排采曲线归纳为3种代表类型。通过对现场资料的总结分析,将煤层气井低产减产的排采因素简单归纳为4类因素。通过调整和优化,使煤层气井产气取得理想效果。The production mechanism of CBM has decided the necessity of dewatering and depressurization of the coalbed methane wells. Reasonable and refined production system which control the coalbed methane wells output is one of the key factors to ensure productivity. This paper analyzes the production mechanism in brief and well drainage curves are divided into three categories. By analyzing onsite data, we can contribute the reasons of the low yield and high yield of coalbed methane wells to four factors, moreover, we can get ideal production of coalbed methane wells through adjustment and optimization.
