摘要
地质勘查向深部拓展是大势所趋,而深部钻探复杂性和难度各具特点,其中,软弱不稳定复杂地层钻进本是钻探工程一大难点。千米巨厚松散覆盖层无套管全裸壁钻进技术是一种大胆探索,成功了即可创建比有套管支护更安全、更经济的钻进方法。
It is a major trend of geological survey to expand deep- er, but deep drilling is complex and difficult, while the drilling of unstable complex layer is a difficulty. The skill of bare wall drilling for uncovered pipe on 1000m thick covering layer is a great exploration, which will create a safer and more economical method if successful.
