利用切片法仿真模拟井眼轨迹的三维可视化

论述了基于井筒切片技术的三维井眼轨迹软件在WPF中的设计思路与实现过程。首先采用三次样条插值法模拟井筒轨迹曲线,然后构建井筒截面切片,最后依次连接各切片并对连接处作贴图渲染处理。可利用导入的参数绘出三维井眼轨迹图,还可利用鼠标操作来实现对三维图形的缩放和视角变换等功能。油气井井眼轨迹的三维可视化以一种直观、逼真的效果呈现给工程技术人员,使其摆脱了抽象和枯燥的井眼数据的束缚,可以更好地解决钻井过程中遇到的各种技术难题。现场数据的测试结果表明,软件能较为精确地反映井下状况,并且操作简便,符合钻井作业的实际需求。

Using the method of slices to simulate well track 3D visualization

This paper discusses the design idea and implementation process of a three dimensional hole trajectory software which is based on the technology of OpenGL in WPF.First of all, the cubic spline interpolation method is used to simulated wellbore trajectory curve.And then, the shaft cross-section slice is built.Finally, it connects each section and does texture rendering with joints.User can use this software to import the necessary parameters.Software will display three dimensional hole trajectory accurately.And users can use the mouse to zoom 3D graphics or change perspective.Tested by site data,this software can show the underground condition accurately, and it is user-friendly controlled.It fits the actual need of drilling operation.
