| Abstract: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. |
