摘　　要：目前水井及地热井钻探效率不高已成为影响水资源开发利用进程的主要因素之一。在分析水井、地热井钻探效率低下原因的基础上,针对不同影响因素,并结合生产施工实际,从优选钻井工艺方法、完善钻井设备配套方面进行论述。提出了大力推广应用地下水开发快速钻进技术——气动潜孔锤钻进技术和气举反循环钻进技术的建议。Low drilling efficiency in water well and geothermal well is one of the main factors affecting development and uti-lization process of water resources.On the basis of the analysis on the causes of low efficiency of water well and geothermal well drilling, according to different affecting factors and combining with the production practice of construction, the paper discusses the optimization of drilling process and improvement of drilling equipment, proposes the popularization of fast drilling technologies of pneumatic DTH hammer drilling and air-lift reverse circulation drilling for groundwater development.
