为了直观形象地观察钻井井眼轨迹，便于钻井井眼轨迹设计和控制，提出一种钻井井眼轨迹三维仿真方法。该方法基于MATLAB软件，采用圆柱螺线内插法进行计算，实现钻井井眼轨迹的三维仿真，并具有图形平移、图形旋转、图形缩放等功能。该方法既可以直接从EXCEL 文档中整体导入测量的离散井眼数据来实现钻井井眼轨迹的三维仿真，也可以对设计的井眼轨迹实现三维仿真；便于将设计的井眼轨迹与实际测量的井眼轨迹进行对比分析，为井眼轨迹的合理设计和有效控制、油田开发方案的制定等带来方便，具有较高的实用价值。

In order to observe well trajectory directly,design reasonably and control effectively,a feasible method to realize well trajectory three-dimensional simulation is proposed.This method bases on MATLAB and uses cylindrical helix interpolation method to calculate in order to realize the well trajectory three-dimensional simulation,and also has functions of moving,revolving,en-large and diminish.This method either can import the measured discrete data directly from the EXcellfile to realize the well traj ectory three-dimensional simulation or can realize the designed well trajectory three-dimensional simulation.This method is easy to analyze the designed well trajectory compared to the measured well trajectory,design reasonably and control effectively,and has considerable practical value.
