【摘要】 传统的钻进工艺要消耗大量的地表水,在干旱缺水地区钻探经常会遇到缺水问题。介绍了一种节水钻探新技术,论述了其工作原理,室内外试验表明该技术能够达到既大量节水又提高钻进效率的目的。在此基础上介绍了一种用于软-中硬岩层中回转冲击钻进的新型球体冲击器的结构、工作原理以及大幅度提高机械钻速并降低成本的试验效果。更多还原

【Abstract】 A lot of surface water will be consumed in the course of drilling when adopting traditional drilling technology,and the trouble of water shortage often occurs when drilling in droughty area.A new technology of water-saving drilling and its working principle be introduced,the results of tests indicate that drilling with the new water-saving technology can save a great deal of water and improve drilling efficiency.Also the structure and working principle of a new type steel ball percussion tools used for rotary percussion drilling in soft-middle hard formations be introduced based on the new water-saving drilling technology,tests on the new type steel ball percussion tools get the results that penetration rate be enhanced by big percentages and drilling cost be cut.更多还原
