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.
