大型深水导管架井口导向同心度的计算方法

Calculating Method for Conductor Guide Deviation of large jacket

描述了一种大型导管架井口同心度的计算方法，用最小二乘法将各层井口中心点坐标拟合成一条空间直线，再计算各个井口导向中心到拟合直线的距离，从而准确地判断井口是否偏离最佳拟合直线。利用VBA编程软件，可以非常快速地计算出结果，大大提高了效率。

Calculating method for conductor guide deviation of large jacket is introduced in this paper, A straight line in space is fit with least square method, and then the distance between the center of the conductor guide and the best fit straight line can Be calculater. So the magnitude of the conductor guide deriation from the best fit straighe line can Be judged, At last, the program is made with AUTOCAD VBA ,which can Be used for calculating the offshore enginteering very guikly and efficienty.
