Rock is a porous medium with complex spatial geometry and different pore sizes. The complex pore structure not only affects the physical properties of the rock, but also creates difficulties for the exploitation of oil and gas and other energy sources. This article describes a new method CDPRM based on three-dimensional digital core. CDPRM uses CT scanning to produce high-precision, high-resolution, and other advantages to construct a three-dimensional model similar to a real core. It uses 3-matic software to convert the digital core into a data model STL file. The 3 D printer prints rock samples and uses them for experiments. At the same time, HYPERMESH software is used to mesh the three-dimensional pore model and import the finite element software to perform numerical simulation. Taking sandstone as an example, a preliminary exploration of the numerical simulation application of CDPRM was conducted. Finally, the development of CDPRM is forecasted, and it is believed that the combined use of 3 D printing production materials and other technologies(such as photoelastic technology) will be the main research direction.
