摘要
经过4年的攻关,国家"863"计划重点项目"2000 m地质岩心钻探关键技术与装备"研制取得了多项创新成果,主要包括:完成了地面钻探设备及孔内钻探取心器具集成配套,形成了深部岩心钻探施工和示范能力;完成了山东金青顶矿区危矿专项ZK43-1钻孔施工,终孔深度2212.80 m。全孔平均钻进时效为1.65 m,岩心采取率为98.6%,钻孔质量优良;创造了3项钻深和套管下入深度全国记录;在大项目运作机制、产学研合作模式及钻探技术示范方式等方面积累了一些经验。详细介绍了项目的研制情况及取得的主要成果。
This paper introduced the main achievements of ＂key technology and equipment of 2000m core drilling＂ in the ＂863＂ project ： integration of drilling equipment and core drilling apparatus has been completed to form the ability of deep core drilling construction and demonstration; the specific project of crisis mine ZK43 - 1 construction in Jinqingding mine was finished with good borehole quality of termination depth 2212. 80m, average drilling efficiency 1.65m/h and core recovery 98.6% ; in this borehole construction, 3 pieces of record of depth in drilling and casing in China were created; and some experiences were accumulated in large project operating mechanism, industry-university-research cooperation mode and drilling technology demonstration mode.
