摘　　要：目前,煤层气井的排水采气工艺采用了油田的有杆泵系统,存在泵阀打不开、卡泵、杆管偏磨等问题,制约了煤层气的开发。环空射流泵排采工艺具有许多优点,已在油田成功应用,特别适用于煤层气井。应结合煤层气井特点,简化地面设备,降低初期投资;改进射流泵结构,提高在小排量时的效率。At present,the rod pumping system were used in CBM wells for dewatering gas produc- tion,and there were many problems,the valve can＇t be open,pump stuck,rod and tubing partial- wear, which restricted the development of CBM. The annular jet pump dewatering process has many advantages, which has been successfully applied in the oil field, and it is especially suitable for CBM wells. What should be done is to combine with the characteristics of CBM wells, simplify the ground equipment, reduce the initial investment,and to optimize the structure of the jet pump, improve the efficiency for small displacement.
