摘要
文中详细介绍了当前国内外采用潜孔锤钻进技术所取得的成就、发展现状及特点,针对直接影响潜孔锤钻进发展的关键技术问题,如钻进的制约因素、钻头的合理匹配、气液混合钻进的合理孔深以及对国产潜孔锤性能的评述等,进行了深入的研究探讨,提出了今后的发展方向。
In this paper achievement and development status of the down hole hammer drilling technique athome and abroad are dealt with.Technical problems having a direct influence to it's development,including controlling factors for the drilling,rational selection of bits,reasonable hole depth selectionfor air-hydraulic drilling and appraisal of the performence of home-made down hole hammers,arediscussed in detail.
