摘要:
井眼轨迹测量过程中存在测量误差,为实现井眼轨迹科学可靠的还原,针对测斜仪测量误差推导出应用于定向井测量环境的误差模型,为促进救险井相交和丛式井防碰提供可靠依据。用实测数据进行计算机仿真,优化后的模型应用到陀螺测斜仪测量数据后,井眼坐标系3个方向的椭球半轴长度都随着测深的增加呈增长趋势,符合测量误差传播的一般规律。研究给出的概率为73.9%的概率密度椭球可真实反映测斜仪在测量过程中存在的测量误差。
Abstract:
Measurement errors exist during the borehole measurement process. Aiming to obtain a scientifically reliable trajectory, an error model for directional measurement environment was derived in this paper. The result could be a reliable basis to promote the relief wells intersect and the cluster wells anti-collision. The new model was simulated in Matlab platform and validated with the field data. The results prove that the semi-axis lengths of three directions have sounding increases with the measured depth increase, in line with the general law of error propagation. The article gives a 73.9% probability density ellipsoid in every survey point which can truly reflect the measurement error during the inclinometer measuring process.
