摘要
SmartMag钻井中靶引导系统由安装于钻头后部的磁信标、安装于靶井中的磁信号采集探管、地表接口箱和磁信号解析软件所组成,它通过测量磁信标在钻进过程中所产生的动态磁场,从而解析出钻头和靶点之间的相对位置参量,最终引导钻进进入靶区或避让靶区。
Built with a magnet beacon sub,a magnetic signal acquisition unit,a magnetic sensor probe and a set of professional analysis software,SmartMag target-hitting guide system interprets the geometry position correlation between the drill bit and the sensor set in the target borehole and finally guides the drilling reaching or avoiding the target area.
