A method to construct high-precision complex pore digital rock
X-ray CT scanning is one of the main methods to study the pore structure of the rocks. However, low
resolution is currently one of the major challenges of this method, which does not allow for the
identification of microscopic pores. Even though adopting images of higher resolutions could reflect
the microscopic pores of the rocks, due to the small size of the scanned rock sample in the x-ray CT
scanning method, the rock parameters cannot be effectively obtained, especially for the rocks with
strong heterogeneity. This would cause the loss of important pore information, such as fractures’
information. Focusing on this problem, the current research tries to propose a method for
constructing high-precision digital rocks of complexly porous rocks. This method is based on the
simultaneous application of x-ray CT scanning images, nuclear magnetic resonance measurements, as
well as mercury injection experimental data and fractal discrete fracture network. These methods
effectively com...
