摘　　要：山西腰站矿区地层破碎,钻进中钻井液漏失严重。本文首先分析了漏失原因,在采取惰性材料架桥堵漏、水泥堵漏方法达不到堵漏效果的时,采取有机凝胶快速堵漏方法取得了一定的成效,在钻孔施工中多次使用,降低了施工成本,保证了成孔质量。The strata are broken and the drilling fluid leakage is serious during drilling at Yaozhan mining area in Shanxi Province.In this paper,the causes of leakage are analyzed firstly.When the plugging methods with inert materials or cement can not achieve the plugging effect,rapid plugging method with organic gel has achieved certain results and has been used many times in drilling construction.The construction cost is reduced and the drilling hole quality is guaranteed.
