Abstract | Tight sandstone possesses multiscale pores. Capturing and modeling the important pore properties into a pore network for drainage is challenging and computationally expensive. We present a method for modeling of a multiscale pore network, which enables us to handle huge rock micro computed tomography (mu CT) images with high computational efficiency and minimal experimental input data. This method uses micro-links to represent the upscaled transport properties of micropores unresolved by the image and connects pore clusters that have topological relationships in the image to extract a connected pore network from it. The size distribution of microlinks is optimized and determined by experimental permeability. The effects of the number distribution of microlinks on flow properties are investigated to obtain the robust parameter. The presented method is validated on a digital core and the published experimental data. This method is successfully applied to rapidly evaluate the influence of mineral components on drainage behavior in two tight sandstone rocks, which involves a large number of computations. The two mu CT images both contain more than 109 voxels and are handled by a personal computer, proving the potential in rapidly, accurately, and conveniently handling huge tight sandstone mu CT image for evaluating the drainage characteristics. |
