多尺度碳酸盐岩的传输特性预测孔隙尺度模型，重建使用连续几何建模技术。该方法结合微晶信息从二维高分辨率图像与沉积相关性从三维低分辨率微计算机断层扫描（micro-CT）图像，以产生校准的孔隙度，结构相关性，并在任意分辨率的传输特性的岩石样品。重建模型的合成micro-CT图像与不同分辨率的实验micro-CT图像匹配良好，从而可以在更高的分辨率下预测物理输运参数。
Transport properties of a multiscale carbonate rock are predicted from pore scale models, reconstructed using a continuum geometrical modeling technique. The method combines crystallite information from two-dimensional high-resolution images with sedimentary correlations from a three-dimensional low-resolution microcomputed tomography ( micro-CT) image to produce a rock sample with calibrated porosity, structural correlation, and transport properties at arbitrary resolutions. Synthetic micro-CT images of the reconstructed model match well with experimental micro-CT images at different resolutions, making it possible to predict physical transport parameters at higher resolutions.
