同径偏斜在岩风阡铝土矿钻探的应用
Application of same diameter deviation in drilling of Yanfengqian Bauxite
摘要
Abstract
During the drilling construction of Yanfengqian Bauxite,the recovery rate of the half soil Bauxite core is often insufficient or directly lost,which seriously affects the evaluation of the ore bed,and may even lead to the abandonment of the borehole.Therefore,in hole sections with insufficient core recovery rate and unsatisfactory quality,supplementary core extraction work must be carried out.The article studies the successful use of the same diameter deviation technology in ZK3607 drilling to supplement ore cores,and summarizes the use of a round steel processing deviation device to replace commonly used drill pipes or core pipes in the past.The combination form of"cement column+drill pipe+deviation device+cement column"is used to replace traditional stone feeding clamping or a single layer of cement fixed deviation device,When inserting the skewer,a new method of same diameter skewing,which replaces traditional iron wire or steel wire rope with a reverse buckle,was adopted.关键词
