斜度超限的钻孔,不但影响地质勘探质量,而且会给钻探施工在技术上造成许多困难,严重者甚至导致钻孔中途报废。对此钻探工作者普遍较为重视,在长期的实践中,也探索、积累了不少防斜纠斜的方法。近年来,我队在赣西巨源和青山矿区外围深部钻探中,也遇到孔斜问题。由于地质 Bored slopes exceeding the limit not only affect the quality of geological exploration, but also cause many technical difficulties in drilling construction. In severe cases, drilling holes can even be abandoned halfway. Drilling workers generally attach more importance to this, in the long-term practice, but also to explore and accumulate a lot of anti-skew correction methods. In recent years, our team also encountered hole inclination problems in the deep drilling of the Gansu Giant Resources and Qingshan Mining Area. Due to the geology
