| 摘 要： | 岩石是具有复杂空间几何分布和不同孔隙尺寸的多孔介质，复杂的孔隙结构不仅影响着岩石的物理性质，同时也为石油天然气等能源的开采带来困难。本文介绍一种基于三维数字岩心的新方法CDPRM，CDPRM利用CT扫描高精度、高分辨率等优点构建类似真实岩心的三维模型，利用3-matic软件将数字岩心转化为数据模型STL文件，导入3D打印机打印岩样并用于实验，同时用HYPERMESH软件对三维孔隙模型进行网格划分并导入有限元软件进行数值模拟。以砂岩为例，对CDPRM的数值模拟应用进行了初步探索。最后对CDPRM的发展做了展望，认为3D打印制作材料混合使用和其他技术（如:光弹性技术）相结合应用将是主要研究方向。

| Abstract: | Rock is a porous medium with complex spatial geometry and different pore sizes. The complex pore structure not only affects the physical properties of the rock, but also creates difficulties for the exploitation of oil and gas and other energy sources. This article describes a new method CDPRM based on three-dimensional digital core. CDPRM uses CT scanning to produce high-precision, high-resolution, and other advantages to construct a three-dimensional model similar to a real core. It uses 3-matic software to convert the digital core into a data model STL file. The 3D printer prints rock samples and uses them for experiments. At the same time, HYPERMESH software is used to mesh the three-dimensional pore model and import the finite element software to perform numerical simulation. Taking sandstone as an example, a preliminary exploration of the numerical simulation application of CDPRM was conducted. Finally, the development of CDPRM is forecasted, and it is believed that the combined use of 3D printing production materials and other technologies (such as photoelastic technology) will be the main research direction. |
