气动潜孔锤钻进工艺在动力头钻机上的应用

Discussion on the Application of DTH Drilling Technology in Well Drilling

气动潜孔锤钻进工艺具有钻进效率高、排屑能力强、清碴速度快、清孔干净、成孔质量好、钻头寿命长、辅助时间少和劳动强度低等优点,所以在水文水井、建筑和桥涵基础工程孔、矿区普查孔的钻探施工中被广泛采用,优势是明显的,因此深受国内外钻探行业的重视.正反循环两种钻进技术结合使用,具有得天独厚的优势,不仅具有显著的技术优势,而且可创造可观的经济效益,可大幅度提高市场占有份额,完成更多的项目施工任务.

The drilling technology with pneumatic DTH hammer used in well drilling process,can greatly improve the quality of well drilling,shorten drilling time,thus,the drilling cost is reduced greatly,which is favored by both domestic and foreign researchers.This technology has such ad- vantages as ability of great removal,high drilling efficiency,long bit life,good-quality well,less auxiliary time and low labor intensity,therefore,used in water well drilling,its advantages are ob- vious.The combination of thes drilling technology and the reverse one,not only has significant technical advantages,but also can create considerable economic benefits,greatly increasing the market share,and completing more project construction tasks.
