摘　　要：排采设备的选择是否合理是保障煤层气井连续、稳定、合理排采的前提条件。煤层气井井型种类多,部分井轨迹复杂,采用的主要排采设备有杆式抽油泵、管式抽油泵、顶驱螺杆泵、电潜螺杆泵、水力同心型无杆泵等多种。根据不同排采设备不同的排采原理,以及它们的优缺点和适用条件,对它们在潘庄区块不同条件的煤层气井的应用情况,从检泵周期、检泵原因以及防偏磨、防煤粉、能否满足沉没度要求等多角度进行了适应性分析,总结出了考虑地面、井筒、储层、费用等多因素条件下各排采设备对煤层气井的适用条件,为潘庄区块及类似煤层气井排采设备的优选提供了重要的参考价值。The reasonable selection of drainage equipment is a prerequisite for ensuring continuous,sta-ble,and reasonable drainage and production of coalbed methane wells.The main drainage equipment used in coalbed methane wells include rod pump,tubular pump,top drive screw pump,electric submers-ible screw pump,hydraulic concentric rodless pump,and other types.Elaborated on the different princi-ples of drainage equipment,as well as their advantages,disadvantages,and applicable conditions.And the application of different drainage equipment in different conditions of coalbed methane wells in Pan-zhuang Block was analyzed.Adaptability analysis was conducted from multiple perspectives such as pump inspection cycle,pump inspection reasons,and prevention of eccentric wear,coal powder,and whether it can meet the requirements of submergence depth.The applicability conditions of various drainage equipment for coalbed methane wells were summarized considering multiple factors such as ground condi-tions,wellbore conditions,reservoir conditions,and cost.This provides important reference value for the optimization of drainage equipment in Panzhuang Block and similar coalbed methane wells.
