摘要
将样条插值方法应用于定向井井眼轨迹的计算,推导出了建立井眼轨迹插值函数的速推公式,为定向井井眼轨迹的计算提供了一个新的方法。利用插值函数可以计算井眼轴线上任一点的坐标、一阶及二阶导数,对井眼轨迹曲线给出一个完整的数学描述。
The spline interpolation method is applied to computingdirectional well path. The formulae for setting up interpolation functions of well path are derived. A new method for computing directional well path is devoleped. The interpolation functions can be applied to computing the coordinates, first order and second-order derivatives at any point in wellbore curves. This paper gives a complete mathematical description of a directional well path.
