储层地质构造模型的三维可视化

Dimension Visualization for Geology-construct-Model of Reservoir

储层地质构造模型的三维可视化可以将测井或地震数据以直观的图形方式显示,是正确认识地下储层地质构造的重要手段。研究了地质层面、整块地质体、断层的三维可视化流程。通过对己知地质数据进行三角剖分和插值,建立了地质层面和整个地质体的三角网格模型。利用OpenGL,在场景中使用变换、投影、光照等技术,实现了储层地质构造模型的三维可视化。显示结果为从局部到整体的多种地质构造三维模型,为制定油田开发方案提供大量可靠的参考。

Three dimension visualization of reservoir geology--constructed--model is used to display the log data and the seismic data in graphics methods directly, which is an important mean to learn the reservioer geo- body structure better. Based on the triangulation and interpolation algorithm to the obtained geology data, the geology layer and hole geology body triangular grid models are constructed. Then three geology- constructed- model visualization methods, geology layer visualization, body O visualization, fault visualization, are analyzed. The data was treating OpenGL in the processes which were mentioned above, using texture, light, fog of OpenGL to make 3D geological body real display, so that three dimension visualization of reservoir geology- constructed- model has realized. In the end, visualization of various geology--constmcted--model is given.
