空气潜孔锤钻进技术在援豫抗旱找水成井施工中的应用

摘要

介绍了空气潜孔锤钻进技术在援豫抗旱找水成井施工中的使用情况、成井工艺及孔内事故处理情况，分析了钻探效益，总结了该次施工取得的经验，得出在河南省太行山区，在无水情况下，运用空气潜孔锤钻进成井工艺取得成功，并可大幅提高钻进效率，保证成井质量，同时降低施工成本，提出今后河南省太行山区深部打井施工中增配专门钻机和增压机的建议。%In this paper, the application of DTH hammer drilling technology in drought resistance Henan, well completion technology and downhole accident treatment are introduced, the drilling benefit studied, the experience in this project is summarized： the application of DTH hammer drilling well completi in is on technology can be successful without water in Taihang mountain area, it can raise the drilling efficiency, gran- tee the well completion quality and decrease the construction cost. It is suggested that it should fit special drill and supercharger in future well construction in Taihang mountain area.
