The invention discloses a gas-water two-phase microcosmic flow simulation model construction method considering distribution of different partition plates, which comprises the following steps of: respectively constructing a semi-permeable partition plate and a semi-closed partition plate in a partition-free geometric model based on a pore geometric shape of a real rock core two-dimensional slice and in combination with pore permeability characteristics of the semi-permeable partition plate and the semi-closed partition plate in a gas reservoir development process; the reliability of the model is proved after verification of a two-phase flow experiment and microscopic flow simulation, and finally geometric parameters of different partition plates are determined. The method is easy and convenient to operate, can be used for gas-water two-phase flow simulation of different partition plate types, can also be used for simulation research of parameters such as gravity, displacement pressure difference, wettability
