Taking the coalbed methane wells in Panzhuang as an example,and based on the develop-ment characteristics of coalbed methane wells,a"522"optimization strategy for the drainage system is proposed.By using classification and big data statistics methods,the drainage system of coalbed methane wells in different types and coal seams is optimized from two dimensions:pump inspection cycle and gas production rate.This study presents a quantitative optimization method for the drainage system of coalbed methane wells at different drainage stages.The findings provide valuable insights and references for the quantitative optimization of coalbed methane drainage system,especially for the extraction of deep coal-bed methane with relatively limited extraction experience.
