Interlayer multiple suppression method, device and equipment and storage medium

The invention discloses an interlayer multiple suppression method, device and equipment and a storage medium, and the method comprises the steps: determining a primary wave reflection coefficient of each target horizon according to the obtained logging data of the target horizon of an earthquake work area, and carrying out the forward synthesis of a primary wave model; performing forward modeling on the acquired to-be-predicted single shot gather data, and synthesizing a multiple model of a single shot gather; fusing the primary wave model and the multiple wave model to obtain a full-wave seismic model; determining a cross correlation coefficient between a forward modeling record of each wave in the full-wave seismic model and an actual seismic trace; according to the cross correlation coefficient, identifying a horizon generating multiple waves; and performing multiple suppression on the seismic data of the horizon to obtain the suppressed target seismic data, thereby realizing accurate identification of the
