【摘要】 随着我国深部找矿、科学钻探以及新能源勘探等深孔钻探需求逐步增长,同时人工成本也大幅提升,亟需开发自动化程度较高的深部钻探成套装备。本文对国家重点研发课题"5000 m地质岩心钻机关键技术与装备研制"样机研制情况进行了概要介绍。该钻机双速顶驱等主要钻进部件采用交流变频驱动,自动井架工、铁钻工、猫道机等井口自动化作业装置采用液压驱动,钻进过程智能化控制,管柱作业基本实现自动化,可以满足金刚石取心钻进和牙轮全面钻进等多种施工工艺要求。更多还原

【Abstract】 With the gradually increase in demand of deep drilling in China, such as deep prospecting, scientific drilling and new energy exploration, and the substantial increase in labor cost, it is urgent to develop a complete set of deep drilling equipment with high degree of automation. In this paper, the authors briefly introduce the development of prototype in the national key research and development project “Key Technology and Equipment Development of 5000 m Geological Core Drill”. The main drilling components of this core drill, such as double-speed top drive, are driven by alternating current(AC) frequency conversion, and the automatic pipe handling system, such as automatic derrick man, iron roughneck and catwalk machine, are driven by hydraulic pressure. With intelligent control of drilling process and basic automation of string operation, this core drill can meet various construction technology requirements such as diamond coring drilling and roller-bit full-face drilling.更多还原
