Research on heterogeneous reservoir grid model 3D visualization optimization method

在油藏三维建模和数值模拟软件中,网格模型在存储格式、网格排序等方面存在较大差异,且大规模网格模型将占用大量存储空间同时需要运算大量数据,限制其绘制速度。为此,提出了异种油藏网格模型三维可视化优化方法,加载异种油藏网格模型,并实现网格模型消隐算法,提高油藏网格模型的绘制速度。实验结果表明,该方法能够加载异种油藏网格模型,与优化前的网格模型相比,优化后的模型在存储、绘制速度和效果上有着明显的优势。

In both 3D reservoir model building and numerical simulation software , different grids models have various differ-ences on storage formats and grids sorting , and large-scale grid model will take up huge storage space and need to compute large amounts of data , which limits the drawing speed of the grid model . To this end , this paper presents a 3D visualization optimization method of heterogeneous reservoir grid model . This method can load heterogeneous reservoir grid model , and realize the grid model blanking algorithm to improve the drawing speed of reservoir grid model . The experiment results show that the method can load het-erogeneous reservoir grid model , and compared with un-optimized grid model , the optimized grid model has a distinct advantage on storage , speed and effect of drawing .
