| 中文摘要:根据沅陵官庄金矿区施工钻孔要求斜度大（最小45°）、矿区岩层岩性复杂、钻进中常遇10～70 m厚破碎带、有较大漏失现象、掉块比较严重、有时有轻微坍塌等情况，有针对性地进行钻头选用、施工工艺选择，并对泥浆配置技术、配制工艺进行研究应用，有效地减少了孔内事故的发生，满足了岩(矿)心采取率要求，大大提高了台月效率。 |

| Abstract:The borehole of Guanzhuang gold field in Yuanling was drilled with high inclination(45°), complex rock lithology, 10-70m fracture zone, serious leakage and block-falling. Drilling bit, construction technology, mud configuration and confection process were studied and selected to avoid the accidence in borehole with satisfied core recovery and increased drilling efficiency. |
