西部特殊景观区深层地下水综合钻探技术论述

On Comprehensive Drilling Technique for Deep Groundwater in Special Sightseeing Area in Western China

西部地区水资源的短缺已严重制约了当地经济的发展,开发深层地下水已迫在眉睫。介绍了深层地下水的概念及合理的找水方法,论述了多工艺空气钻进技术体系的主要内容,同时提出液动潜孔锤冲击回转钻进技术、气举反循环钻进技术、定向分支孔钻探技术等多项先进技术可用于西部地区水资源快速勘探的观点。

The shortage of water resource in the west of China has severely limited local economic development, and the exploitation of deep groundwater became extremely urgent now. The passage introduced the concept of deep groundwater and some advisable method in water detection, explained multi-technologies air drilling technique. Some advanced technologies were suggested to adopt for exploration of water resource： hydro-hammer percussive rotary drilling, air-lift reverse circulation drilling and directional branch-hole drilling.
