Error compensation method of mine-used drilling trajectory measurement system
-
摘要: 介绍了随钻轨迹测量系统构成和测量原理,从传感器自身误差、工况环境误差、传感器安装误差3个方面详细阐述系统误差来源及其补偿方法。通过模拟水平定向钻进物理场景并分析比较误差补偿前后的姿态角可知,对不同误差源作出相应的误差补偿可以提高姿态角测量精度。Abstract: The paper introduced structure and measuring principle of drilling trajectory measurement system, and elaborated error sources and compensation method in details from three aspects including sensor itself, environmental conditions and sensor installation. The simulation of the physical scene of horizontal directional drilling, and analysis of attitude angle before and after the error compensation show that making appropriate error compensation for different error source can improve the accuracy of attitude angle measurement.
