Visual micro-pore structure simulation physical model and manufacturing method thereof

The invention mainly belongs to the technical field of oil and gas field microcosmic mechanism research and particularly relates to a visual micro-pore structure simulation physical model and a manufacturing method thereof. The simulation physical model comprises a primary board and a secondary board. The secondary board comprises an injection port and a recovery port. The primary board is formed by mixing epoxy resin and a curing agent. The secondary board is formed by processing planar optical glass. The primary board comprises a pore network structure which is composed of three parts. The front ends of the three parts of the pore network structure are connected with the injection port through a common throat, and the tail ends of the three parts of the pore network structures are connected with the recovery port through a common throat. By means of the method, the throat diameter, any throat-to-pore ratio and various coordination numbers under micrometer size can be achieved, and the manufactured physical model is good in transparency, high in visualization and low in manufacturing cost.
