摘　　要：文章通过对近9年煤层气井不停产洗泵技术在贵州地区的应用及理论和实践改进的研究,总结分析了在贵州地区77口煤层气直井或定向斜井运用煤层气井不停产洗泵技术289次的情况,其很好的解决了粉末状固相物质导致的泵故障问题,大幅降低了检泵频率,将检泵周期极大幅延长,很好的保证了煤层气井排采的连续性和稳定性,避免了粉末状固相物质导致检泵给井产生的产气下降等伤害,同时节约了大量生产成本,多维度提高了煤层气勘探开发效益。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 coalbed methane exploration and development from multiple dimensions.
