The invention provides a three-dimensional seismic horizon attribute slice quantification color code correction method, and belongs to the technical field of oil and gas field development. Firstly, three-dimensional seismic attribute slice data and logging data of a target area are acquired; establishing a well-seismic time-depth relationship between the two layers, determining depth data of the top and the bottom of the logging layer, and determining reservoir parameters within the depth range; respectively setting a plurality of threshold values to divide the seismic attributes and the reservoir parameters, and performing cross calculation on the coincidence rate of the seismic attributes and the reservoir parameters corresponding to each reservoir parameter threshold value under each seismic attribute threshold value division; and finally, selecting a threshold value corresponding to the optimal coincidence rate to adjust a three-dimensional seismic attribute slice color code value, and realizing three-dim
