摘要
分析了新疆阿舍勒矿区地层特点,从钻孔结构及钻具级配、钻探设备选择、钻进工艺技术、护壁堵漏技术及钻孔控斜技术等几方面总结了在阿舍勒矿区进行深孔钻探施工的技术经验,并针对矿区钻探施工中存在的地层复杂破碎、钻孔漏失、地层促斜严重等问题,提出了应对的技术措施。
The paper analyzes the formation characteristics in Ashele mining area of Xinjiang and sums up the deep drilling experiences in hole structure and drilling tool grading, drilling equipment selection, drilling technology, wall protection and shut-off technology as well as drilling deviation control technology in Ashele area. According to the complicated broken formations, hole circulation loss and serious deflection-promoting in strata, the relative technical measures are presented.
