摘　　要：陕北石炭二叠纪煤田矿区位于黄土高原地区,绳索取心深孔施工极易出现全漏失、冲洗液失效等难题,在总结以往该地区常规钻探施工和多年工作经验的基础上,ZK1号钻孔使用施工能力强的设备,并优化钻孔结构,优选钻头工具,应用耐高温冲洗液,提高了生产效率,实现了安全终孔。The Carboniferous Permian coalfield mining area in northern Shaanxi is located in the Loess Plateau area,where the construction of deep wire line coring holes is prone to full leakage,failure of flushing fluid and other problems.On the basis of summing up the previous conventional drilling construction in this area and our team’s years of work experience,ZK1 borehole uses equipment with strong construction capability,optimizes the drilling structure,optimizes the drilling tools,and applies high-temperature resistant flushing fluid,which improves the production efficiency and realizes safe hole finishing.
