地质工程一体化油藏模型高效可视化技术

Efficient Visualization Technology of Geology-Engineering Integration Reservoir Model

针对实时绘制大规模油藏地质网格模型存在速度慢、效果差等问题,在分析Eclipse油藏网格模型存储格式、网格模型的表示及单元格排序规律的基础上,提出一种新的网格模型消隐算法,对原始网格数据进行优化,从而提高油藏网格模型的绘图显示速度。通过油藏地质模型与井轨迹三维可视化软件的具体实现,验证了消隐算法的正确性和效率。软件中首先通过预处理有效减少了显示网格的数量,采用WPF和Helix三维图形技术,实现了油藏模型的高效显示。对不同规模的油藏模型进行对比测试,证明了该方法可减少85%以上的点和面数据,显示速度和优化效果显著。软件有助于钻井解释与决策,为钻井过程提供合理的随钻跟踪地质目标钻井方案,实现地质工程一体化的无缝衔接。

In view of the slow speed and poor effect of real-time rendering of large-scale reservoir geological grid model,a new grid model hidden algorithm is proposed by analyzing the storage format,grid model representation and cell sorting rule of Eclipse reservoir grid model,which optimizes the original grid data and improves the rendering speed of reservoir grid model.The correctness and efficiency of the hidden algorithm are verified through the visualization realization of reservoir geological model and well trajectory using 3D visualization software.In the software,firstly,the number of display grids is effectively reduced by preprocessing,and the high-efficiency display of reservoir grids is realized using 3D graphics technology of WPF and Helix.The comparison test of different scale reservoir models shows that the method can reduce the point and surface data by more than 85%,and shows that the speed optimization effect is significant.The software is helpful for drilling interpretation and decision-making,provides reasonable drilling scheme for tracking geological targets while drilling,and realizes the seamless connection of geological engineering integration.
