摘要
在水井施工中气动潜孔锤钻进是一种快速钻进方法,该方法在2010年山东省抗旱应急找水抢险施工中得到广泛应用,效果显著,但是部分钻孔出现孔斜现象。从地质、工艺和技术等3个方面分析了产生孔斜原因,提出了防斜措施,确保水井施工后续的成井工作顺利实施。
In the water well construction, pneumatic DTH hammer drilling is a kind of fast drilling method, which was widely applied in drought -resistance and water exploration emergency construction in Shandong in 2010 with obvious effects,but deviation appeared in some drilling hole.The causes of hole deviation is analyzed in aspects of geology, process and technology in this paper and prevention measures are put forward to ensure the smooth implementation of subsequent well formation construction.
