Summary:The invention provides a scattered wave post-stack imaging method and device, electronic equipment and a storage medium, and belongs to the technical field of seismic wave imaging, and the method comprises the steps: carrying out the regional blocking of a reverse time migration image in a spatial dimension, and obtaining the reverse time migration image of each block region; performing three-dimensional discrete Fourier transform on the reverse time migration image of each area to obtain a reverse time migration image of a wave number domain; filtering the reverse time migration image of the wavenumber domain to obtain a wavenumber domain scattered wave imaging result; performing discrete inverse Fourier transform on the wavenumber domain scattered wave imaging result to obtain a spatial domain scattered wave imaging result; and splicing the spatial domain scattered wave imaging results in each block region to obtain a complete scattered wave post-stack imaging result. The device comprises a blocking module,
