Yanchuan south block of coallbed methane production wells for coal from the row in the coal separa- tion to cause frequent card pump shaft screw pump, prosecutors pump cycle is short, unable to realize the con- tinuity of the coalbed methane in row. This paper introduces Yanchuan south block CBM row production Wells technology situation lifting, and find out the screw pump row in the process of mining, the main problems of the corresponding technical countermeasures to improve the whole block Yanchuan CBM development level has certain directive significance.%延川南区块煤层气部分排采井因煤粉从煤层中析出至井筒造成螺杆泵频繁卡泵,检泵周期短,无法实现煤层气的连续性排采。文中介绍了延川南区块煤层气排采井举升工艺技术现状,找出螺杆泵排采工艺中存在的主要问题,提出相应的技术对策,对提高延川南区块煤层气整体开发水平具有一定的指导意义。
