钻孔漏失是钻探工程工艺中重要技术问题之一，它直接影响到钻进效率，阻碍钻探经济效果的进一步提高。对于钻孔漏失的预防和处理，一直是我局存在的一个技术关键课题，通过多年探索与实践，在一些较有代表性的矿区取得了点滴经验。
Drilling hole leakage is one of the important technical problems in the drilling engineering process, which directly affects the drilling efficiency and hinders the further improvement of the drilling economic effect. The prevention and treatment of the drilling loss has always been a key technical issue for our bureau. Through years of exploration and practice, we have gained some experience in some representative mining areas.
