description The invention relates to a method for analyzing the preservation or not of early particle dissolution pores of a sandstone in the burial compaction process. The method concretely comprises the following steps: S1, preparing an earth surface modern deposit sample having the same structural fabric with a middle-deep stratum sandstone rock; S2, obtaining the real stratum water density of the actual stratum of the middle-deep stratum sandstone, the overlying stratum density, the earth temperature gradient and the earth surface average temperature, and calculating the pore fluid pressure, the static rock pressure and the stratum temperature meeting actual geologic conditions; S3, carrying out a mechanical compaction simulation experiment meeting the actual geologic conditions on the sample; S4,processing the sample after the experiment; and S5, analyzing the experiment sample and experiment data. The method can truly reflect the final preservation condition of the early particle dissolution pores after the modern
