摘　　要：武乡南煤层气研究区由于煤层埋藏较深,煤质较软,在排采过程中,压裂砂、煤粉等物质随排采液进入井筒并在井底沉积,造成气井卡泵、故障停机,降低煤层气井产量。文章基于该区块煤储层地质特征及排采中存在的以上问题,研究提供了一种用于深部煤层气水平井捞砂的捞砂工艺。Due to deep coal seam burial and soft coal quality in south Wuxiang CBM research area,fracturing sand,pulverized coal and other substances enter the wellbore with the drainage fluid and deposit at the bottom of the well during drainage and production,resulting in gas well stuck pump,failure and shutdown,and reduce the production of CBM Wells.Based on the geological characteristics of block coal reservoirs in this area and the above problems existing in drainage and production,a sand bailing technology for deep coalbed methane horizontal Wells is presented in this paper.
