摘　　要：水平水井是开采浅层低渗透性含水层地下水的有效方法,水平水井施工包括钻进、护壁、扩孔、井管安装、填砾、洗井等步骤。对导向钻进铺管技术在浅层低渗透性含水层地下水开采中的工艺进行了详细探讨。通过研究,研制出了适合水平水井施工的过滤器,提出了相适应的钻进方法和成井工艺,为浅层低渗透性含水层地下水开采提供了一种新方法。The horizontal water well is effective for shallow least permeable aquifer groundwater extraction. The procedures for the construction include well drilling, bore hole reaming, well forming, gravel packing, and well development. This paper discusses the application of horizontal directional drilling technology in shallow least permeable aquifer groundwater extraction. A pre-paeked well screen is developed and a proper well drilling method is proposed for the construction of horizontal wells. This provides a new way for shallow least permeable aquifer groundwater extraction.
