Abstract
Micron-CT technology can make up for many shortcomings of traditional rock physics experiments and provide a new platform for rock physics research. In this paper, a 3D digital core model with realistic pore structure characteristics was established using micron-CT scanning combined with advanced image processing techniques with carbonate rocks as the research object. Various morphological algorithms included in the digital core software (Avizo) are applied to quantify and characterize the pore structure of digital cores, and obtain the characteristics of total porosity, effective porosity, pore and throat equivalent radius distribution, and establish an equivalent pore network model. The absolute permeability experiment module was applied in the digital core software (Avizo) to realize the simulation of seepage on the micron scale and calculate the absolute permeability. This paper enriches the existing digital petrophysical research tools by applying digital core software (Avizo), which is of great significance to deepen the understanding of hydrocarbon storage and transport mechanisms inside the reservoir.
