摘要
SmartMag定向中靶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等组成,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。介绍了SmartMag定向中靶系统在土耳其贝帕扎里天然碱矿采集卤钻井工程中的工业性入井试验的应用情况。该系统在前期研发中打下了良好的技术基础,因此在首次入井试验中就取得了一次中靶的良好效果。
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 guidance system interprets the geometry position correlation between the drilling bit and the sensor set in the target borehole and finally guides the drilling reaching or avoiding the target area.The paper introduced industrial test trial on SmartMag target-hitting guidance system.Based on the earlier researches,the successful operation results have been achieved during the practical test trial of the system.
