| Abstract: | 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. |
