基于OSG的油藏三维可视化系统研究

Study of three-demensional visualization system for reservoir based on OSG

为了直观、逼真地展现地下油藏构造的真实形态及储层物性参数的分布规律等,设计并实现了一种基于开源软件OSG的油藏三维可视化系统。该系统充分利用OSG的特点和功能,完成了三维油藏模型漫游、缩放和任意剖切等交互操作功能。同时重点研究实现了绘制油藏彩色模型、提高网格模型视觉效果等技术。将该系统应用于中石化胜利油田实际油藏区块,取得了较好的效果。

In order to show the intuitive and realistic real form of reservoir geological structure, the distribution of reserwoir physical parameter, a reservoir 3D visualization system based on open source software OSG （Open Scene Graph） is designed and im- plemented in this paper. The system makes full use of features and functions of OSG, realizing 3D reservoir model roaming, zoom- ing, arbitrary cutting functions. It also focuses on rendering reservoir color model and improving grid model visual effects, etc. Fi- nally, the system is applied to the actual reservoir block of sinopec shengli oilfield, and the results are desirable.
