| 中文摘要:在青海埃坑南矿区钻遇含角砾石的断层泥地层，孔壁坍塌、掉块，卡钻事故时有发生，几乎无法继续钻进，使用水玻璃与相关钻井液处理剂配合使用制备水玻璃钾基抑制冲洗液，用来平衡地层压力保护孔壁，并且加大金刚石钻头及扩孔器外径，解决了钻孔坍塌、缩径以及卡钻等问题，使施工顺利进行，为后续施工提供了参考方法。 |

| Abstract:The fault gouge formation containing breccia was drilled in the south of Aikeng mining area of Qinghai Province, continuous drilling was almost impossible, because borehole collapsing, block falling and sticking often occurred. By the match usage of sodium silicate and related drilling fluid additives, sodium silicate potassium base inhibition flushing fluid was prepared to protect the hole wall by the formation pressure balance; and by increasing the outside diameters of diamond bit and reamer adjusting, borehole collapse, shrinkage, and sticking were solved. |
