摘　　要：鄂尔多斯北区油气勘探开发进入了一个试验开发新阶段。在钻井实践中,发生了大量的钻具失效事故,极大地影响了钻井速度。通过对鄂尔多斯北区钻具失效事故的数据统计,对钻具失效形式进行分类,分析了钻具失效的主要机理;提出了预防和减少钻具失效的技术措施。现场应用后,大幅度减少了钻具失效事故,对今后在该地区钻井施工有一定的指导作用。Oil/gas exploratory development has entered into a new stage in North area of Eerduosi. During drilling, a mass of drilling tool malfunction accidents were occured, it has affected severely the drilling speed. Based on the data statistics of drilling tool malfunction accident, the drilling tool malfunction modes were the classified in the North area of Eerduos, and the main mechanisms of drilling tool malfunction were analyzed. At the same time, and the prevention and improvement measures for reducing the drilling tool malfunction have been proposed. Through field application, drilling tool malfunction accidents were reduced by a big margin.
