description The invention relates to a post-stack amplitude compensation method of seismic attributes. The method comprises: amplitude data are extracted from post-stack seismic data; a mean-square-root amplitude or absolute amplitude A of an attribute point is obtained, wherein the A is expressed by a formula 1, x and y in the formula 1 express plane coordinates of the attribute point and z expresses an amplitude value at the coordinates x and y; paleostructure in coal seam deposition is recovered, a relative elevation difference H ' is calculated based on the paleostructure, wherein the H ' is expressed by a formula 2, h in the formula 2 expresses an elevation value at the coordinates x and y and C expresses an elevation difference value of the paleostructure; a crossed analysis is carried out on the mean-square-root amplitude or absolute amplitude A of the attribute point and the relative elevation difference H ' to obtain a correction function F(H ') related to a relationship between the amplitude and the relative el
