| 中文摘要:土耳其贝帕扎里天然碱矿采卤工程是目前世界范围内采用对接井水溶开采方法进行采矿的最大规模的天然碱采矿工程。在对接井施工过程中，由于出现了地磁变化异常和地质条件变化，致使MWD导向系统出现了一定偏差。为减少仪器偏差，设计并对仪器进行了实地校核。校核结果表明，探管的安装条件对其数据精度有较大的影响。其校核结果被应用于实际生产中，起到了良好的指导作用。 |

| Abstract:Currently in the whole world, Beypazari trona solution project is the largest mining engineering with the methods of solution mining and intersected well drilling. Due to the geological condition changes and abnormal earth magnetism behavior, some abnormal deviations happened with the MWD device. An in-situ probe calibration work is designed and preformed so as to find what influences the probe measurement precision. The calibration results show the assembly condition of MWD probes greatly contributes the deviation of measurement, thus some measures are necessarily taken to prevent from such errors in the well drilling construction. |
