摘要

摘要: 在煤层气排采分析及数值模拟研究中，煤储层结构的三维建模是数值模拟和结果分析的起点，具有关键作用。三维长方体等传统网格，难以表达地层的起伏变化，角点网格具有表达起伏变化地层的优势。从煤层气动态可视化的角度出发，基于角点网格建立了煤储层三维地质模型。研究了角点网格模型的数据特点及生成角点网格的方法，采用C#编程语言并结合OpenGL图形接口，开发了煤储层三维可视化软件模型，利用该模型表达了山西省沁水盆地潘庄区块的煤储层地质构造。结果表明，角点网格适用于煤储层三维模型的构建，能较好的表达煤层的结构特征。

Abstract: In the study of CBM's drainage analysis and numerical simulation, 3D geological model of coal reservoirs structure is the starting point for numerical simulation and results analysis, which plays an important role. Three dimensional cuboids and other traditional grid can not express the changes of strata, but corner-point grid has the advantage of doing it. From the point of dynamic visualization of CBM, the paper established a 3D geological model of coal reservoir based on corner-point grid, studied the characteristics of data and the method to generate corner-point grids of CBM, developed a three dimensional visualization interface of coal reservoir using C# programming language combined with OpenGL graphic interface, expressed the coal reservoir geological structure in Panzhuang area, Qinshui basin, Shanxi Province with the model. The results show that corner-point grid is suitable for constructing 3D model of coal reservoir, which has a good expression of the structural characteristics of coal seam.
