| 中文摘要:在介绍朱溪矿区钻遇地层特点的基础上，系统分析了钻孔深度大、易斜，相对浅孔而言地层更复杂，钻孔质量要求尤其是孔斜要求更为严格等施工难点，总结了主要钻探装备选用和钻探施工管理工作，以及钻进方法、钻孔结构、钻头选用、钻进技术参数、冲洗液选用、护孔堵漏措施等。建议今后深孔施工中必须提高钻探装备的施工能力、遏制重大孔内事故发生、坚持预防为主治理为辅的孔斜防治原则、抓好泥浆护孔等工作。 |

| Abstract:Based on the introduction of drilled strata characteristics of Zhuxi mining area, the construction difficulties are analyzed systematically in the aspects of deep drilling depth and easily being inclined, more complex formation comparing with shallow drilling, higher requirements of drilling quality, especially for hole inclining and some others. This paper summarizes the main drilling equipments selection, drilling construction management works and major technologies including drilling methods, hole structures, drill bit selection, drilling technical parameters, flushing fluid selection and hole wall protection and plugging measures; suggests improving construction capability of drilling equipments, curbing serious downhole accidents in future deep hole construction, insisting on the control principle of prevention first and treatment secondary and being prepared for hole wall protection with mud. |
