摘　　要：浅层低渗透性含水层埋深浅、渗透性低,难以用常规管井开采。利用水平定向钻井技术,可在含水层内长距离铺设过滤器,从而增大水井出水量。研制的贴砾过滤器,其性能经水平井试验验证满足水平井成井要求,取得了良好的试验效果。Horizontal water well is effective for shallow low permeable aquifer groundwater extraction.The construction procedures include well drilling,bore hole reaming,well forming,gravel packing and well development.The technical issue of horizontal directional drilling technology is discussed in the paper,pre-packed well screen was developed and proper drilling method for horizontal well construction was proposed.It provides a new way for shallow low permeable aquifer groundwater extraction.
