摘　　要：通过井眼位置进行监测,对轨道偏移进行提前预测,能够很好地对井眼轨道控制提供判断依据.综合考虑导致轨道偏移的系统、仪器等各方面因素,对误差椭球三个半轴的计算进行研究,加入绕主法线旋转角度,使得误差椭圆角度更准确.利用OpenGL技术,实现了误差椭球的三维可视化,从而能够直观地看出误差的大小以及下一步发展方向,为井眼轨道控制以及井眼防碰提供参考.By verifying the well bore position and predicting the error of well trajectory, the direction of well trajectory is better controlled. Taking account of the facet of system and instruments which influence the error of well trajectory, three semiaxises of error ellipsoid are calculated. Angle rotating based on normal direction is adopted to improve the accuracy of the ellipsoid. Using the technology of OpenGL, 3D visualization of error ellipsoid is realized, which can show the size and direction of well trajectory error, and provide references on controlling well trajectory.
