石油钻井井眼轨迹三维可视化建模

Modeling of 3D Visualization for Wellbore Trajectory

为便于钻井人员直观地观察、分析及有效地控制井眼轨迹,该文从基于切片建立三维几何模型的思路出发,根据不规则三角网（TIN）构网和三维几何变换提出了一个新的筒状井眼轨迹的三维可视化建模方法。该方法不需要对井眼轨迹弯曲处进行插值圆滑处理,高效快捷地实现了筒状井眼轨迹的无缝连接。详细描述了井眼轨迹的建模方法,为＂临境＂观察、控制石油钻采的三维可视化打下了基础。

In order to directly observe,analyze and effectively control the drilling trajectory for the drill staff,this paper puts forward a new method for the tubular wellbore trajectory which bases on slices modeling,Triangulated Irregular Network（TIN） and 3D geometric transformation.The method implements the 3D tubular wellbore trajectory seamless connection efficiently and conveniently without interpolation smoothing treatment of the wellbore trajectory＇s bender.It also details in the wellbore trajectory modeling and also lays the foundation for the ＂person on the scene＂ observation and controlling three-dimensional visualization of oil drilling.
