摘要
讨论了如何利用最小二乘曲线拟合对井架变形监测数据进行处理,并通过试验得到了拟合精度最高的多项式阶数和拟合曲线。最小二乘曲线拟合有效地消除了观测数据的偏差,准确地反映了井架的变形量,是井架变形监测数据处理的一种有效方法。
This paper discussed how to use the least-squares curve fitting on the derrick deformation monitoring data processing, and obtained the highest order of the polynomial curve fitting according to the experiment results. Least-squares curve fitting effectively eliminated the bias and accurately reflected the deformation of the derrick. It is an effective method of derrick deformation monitoring.
