| 摘 要： | 小秦岭金矿田地区地质构造较为复杂，破碎漏失地层厚度大，该矿区钻探施工多次出现不同程度的烧钻事故，严重影响了钻探效率和钻探成本。针对Q8ZK801钻孔烧钻事故，通过反卸钻杆和磨铣事故钻具的方法，并配合加工的简易绳索打捞器、磨铣导正器进行处理，取得了良好效果，成功解决了烧钻事故。本文就该次事故发生的原因及事故处理方法做了详细的分析与总结，并对烧钻事故的预防进行探讨，为该矿区钻探施工提供参考，并为此类事故的处理提供借鉴。

| Abstract: | The geological structure is very complex in Xiaoqinling area with thick crushed stratum. Different degrees of bit burning accidents often appear in the drilling construction in this area, which seriously affected the drilling efficiency and drilling cost. For bit burning accident in Q8ZK801, through the methods of reverse screwing the pipe and milling the drilling tools matched with processed simplified wire-line fishing tool and milling centralizer, the accidents have been successfully resolved with good effect. This paper analyzes and summarizes the accident causes and bit burning accident handling methods in detail and discusses the prevention to provide reference to mining area drilling. |
