三维水平井轨道优化对齐设计模型

3D Trajectory Optimization Alignment Design Model for Horizontal Well

针对现有三维水平井轨道计算方法程序复杂,迭代计算过于繁琐的问题,形成了基于空间圆弧曲线优化对齐方法的水平井轨道优化设计模型和简易算法。将水平井的轨道设计问题,转化为带有三角函数的多元一次方程组求解问题。根据该算法,只要确定了造斜点、靶点,并预设合理的第一、第二圆弧段狗腿度,就可以精确计算出水平井的各项轨道参数,参数求解具有唯一性。为轨道设计和软件编程人员提供了一种新方法。

A horizontal well trajectory optimization design model and simple algorithm based on the spatial arc curve optimization alignment method are formed in order to solve the complexity and too cumbersome iterative calculation of the existing 3-D horizontal well trajectory calculation method.It transforms the trajectory design of horizontal wells into the solution of multivariate linear equations with trigonometric functions.According to the algorithm in this paper,As long as the deflecting point and target point are determined,and the reasonable dogleg degrees of the first and second arc segments are preset,the trajectory parameters of the horizontal well can be accurately calculated,and the parameter solution is unique,which provides a new method for horizontalwell trajectory designers and software programmers.
