摘要
回顾总结了汶川地震断裂带科学钻探(WFSD)项目钻探装备的研制和改造过程,详细描述了2种高速顶驱式岩心钻机的总体方案、应用效果和存在问题,简要分析了高速顶驱钻进、顶驱/转盘双回转钻进以及交流变频电驱动技术在深部复杂地层钻探领域的应用前景,对建立我国深部钻探装备体系具有一定的参考价值。
This article gives us a review of research and development of a deep hole drill rig developed for Wenchuan Earthquake Fault Scientific Drilling Project,introduces the scheme of high-speed top-drive rig for deep core drilling( including hydraulic drive and AC VFD),analyses the application perspectives of high speed top-drive,dual rotary system and AC VFD in deep hole coring and in complicated formation condition.
