| 摘 要： | 提出了一种基于多孔介质二维薄片图像和多点统计方法的多孔介质三维重构方法.将微米精度的多孔介质二维薄片图像作为初始的训练图像,利用多点统计方法重构其下层图像.将每次获得的下层图像作为新的训练图像,利用多点统计方法继续重构该训练图像的下层图像.二维重构图像的每个像素对应成三维空间的一个体素,依次叠加每层的二维重构图像得到最终的三维多孔介质图像.将该方法应用于砂岩样品的三维重构,通过与真实情况下砂岩体数据的比较发现,该方法重构的多孔介质具有与其相似的孔隙结构特征.

| Abstract: | A method using a two-dimensional thin section image of porous media and multiple-point statistics to reconstruct the three-dimensional structures of porous media was proposed.A two-dimensional thin section image of porous media with the resolution of micron was used as an original training image.The two-dimensional reconstruction image of the next layer obtained each time was taken as a new training image.Multiple-point statistics is used to reconstruct the image of the next layer of the new training image.... |
