Based on the application of non-stop pump cleaning technology in coalbed methane wells in Guizhou over the past nine years as well as the research on theoretical and practical improvements,this paper summarizes and analyzes the situation in which the non-stop pump cleaning technology applied for 289 times across 77 vertical or directional coalbed wells in Guizhou.This technology effectively solves the pump failure issues caused by powdered solid substances and significantly reduces the frequency of pump inspections and greatly extends the inspection cycles,ensuring the continuity and stability of coalbed methane well drainage.This approach prevents the decline in gas production caused by pump inspections due to powdered solid substances,saves substantial production costs,and improves the efficiency of coal-bed methane exploration and development from multiple dimensions.
