大直径贯通式潜孔锤局部气举反循环钻进工艺的试验研究
摘要:试验在厂内50 m试验井进行,试制SH25H液压风动冲击钻机。配置可伸缩式钻杆保证连续进尺,采用大直径贯通式气动潜孔锤组合局部气举反循环钻进工艺。试验表明,钻进效率和钻孔质量显著提高,为多工艺冲击回转钻进技术增砖添瓦。
Abstract:Through actual drilling tests in the 50 meters wells, the SH25H hydraulic pneumatic impact drill was trial manufactured with the pneumatic DTH and local inverse circulation rotary drilling technology, and continuous footage was ensured by retractable drill pipe. The multi-techniques drilling technique is developed with high drilling efficiency and high quality of borehole.
