A method and a system for measuring the pore structure of tight sandstone are provided. The method comprises the following steps: carrying out the desorption experiment of a core sample saturated by a specific gas containing isotope element to obtain the pressure of the specific gas and the total isotope ratio at each sampling moment; acquiring a single isotope ratio of each pore diameter at each sampling moment according to a physical model containing pore diameter parameter and the pressure of the specific gas at each sampling moment; and obtaining the proportion of a pore of each pore diameter in the core sample. The method and the system for measuring the pore structure of the tight sandstone provided by the disclosure can quickly obtain the pore distribution of the tight sandstone without damaging a sample.
