汶川地震断裂带科学钻探项目深孔取心钻探设备的研制与应用
Exploration Engineering(Rock & Soil Drilling and Tunneling)(2012)
Abstract
深孔取心钻探设备是为满足汶川地震断裂带科学钻探项目(WFSD)3000 m深部取心钻探需要而自主研制的我国首套科学钻探专用设备,包括KZ3000型全液压钻机以及深部钻探配套用高压泥浆泵和钻杆钻具等。该套设备集全液压、高速顶驱、大口径、深部取心于一身,具有综合能力强、工艺适应性广、操控智能程度高等特点,在WFSD-2孔深部取心钻探中,各项功能满足设计要求,应用情况良好。该套设备作为我国深部钻探装备的阶段性创新成果,在科学钻探、深部找矿和浅层油气钻采中,具有一定的推广价值。
