摘　　要：攀枝花地区米易县白马钒钛磁铁矿整装勘查工作是四川省地勘基金启动项目,任务重、时间紧,加之所在区域地层复杂,上部漏失,下部多遇断层破碎带,造成钻孔事故频发,钻探效率低下,甚至无法施工,严重阻碍了勘查工程的顺利推进。针对这一施工难题,通过反复试验研究,探索出了一整套行之有效的深孔复杂地层护壁堵漏技术体系,确保了整装勘查项目的顺利完成。详细介绍了该矿区泥浆护壁堵漏技术及其效果。The borehole accident frequently occurred in the whole mount exploration in Baima vanadium-titanium of Panzhihua area with leakage in upper part and fault fracture zone in lower part.The low drilling efficiency brought along seriously affected the exploration construction.According to this difficult problem,by the repeated tests and studies,a set of effective wall protection and leakage control technical system was developed to ensure the successful accomplishment of whole mount exploration.Mudding leakage control and wall protection technology and the effect in this area were presented.
