摘　　要：L型套管压裂水平井在低渗或深部煤层气田开发上具有很大的技术优势,电潜螺杆泵举升工艺为水平井排采的重要方式之一,具有排量大,设备占地面积小,调参方便,自动化程度高等技术优势。通过现场270余口井的排采实践,发现该类泵型存在卡泵、烧泵等5类故障,分析总结了各类故障发生前后的生产特征及原因,提出4类针对性预防及后期治理对策,研究结果为电潜螺杆泵在沁水煤层气田的稳定排采奠定了基础,同时也为其他煤层气区块的开发提供了借鉴经验。L-type casing fractured horizontal wells have great technical advantages in the development of low-permeability or deep coalbed methane fields.As one of the important methods for horizontal well drainage and production,the electric submersible screw pump lifting process has technological advantages such as large displacement,small equipment footprint,convenient parameter adjustment,and a high de-gree of automation.Based on drainage and production practice from over 270 wells on site,it is identified that this type of pump has 5 types of faults such as pump jamming and pump burning.The production characteristics and causes before and after each type of fault are analyzed and summarized,and 4 targeted prevention and later treatment measures are proposed.The research results lay the foundation for stable drainage and production of electric submersible screw pumps in the Qinshui coalbed methane field,and also provide a reference for the development of other coalbed methane blocks.
