| 中文摘要:山西腰站矿区施工的ZK6004钻孔，设计孔深1450 m，地层复杂，而且全孔漏失，极易发生烧钻事故。就该孔连续发生的2次烧钻事故，进行了事故原因分析、处理方法的经验介绍。2次烧钻事故的处理过程中，根据实际不同情况，分别采用了掏眼法和冲砸法。这是深孔烧钻事故处理新方法、新尝试。同时总结了漏失深孔烧钻事故的预冲孔经验及预防措施。对于今后在复杂漏失地层深斜钻孔的施工有一定的借鉴价值。 |

| Abstract:The designed depth of ZK6004 was 1450m in Yaozhan mining area of Shanxi with complex formation and hole leakage, the bit burning occurred easily because of this situation. The paper introduces the treatment experience of 2 bit burning accidents in this hole with the analysis on the causes. According to the different conditions, new methods of hole cutting and impacting were adopted. At the same time, the paper also summarizes the experience of pre-washing and the preventive measures for bit burning in deep hole with circulation loss, which can be reference to deep inclined borehole construction in leakage formation. |
