Zusammenfassung:The invention discloses a seismic data processing method and device. The method comprises the steps: obtaining original seismic data, and acoustic wave time difference curves and density curves of a plurality of logging points; determining seismic wavelets according to the original seismic data; according to the seismic wavelets, carrying out deconvolution processing on the original seismic data, and determining a stratum reflection coefficient frequency spectrum of the seismic data; determining a stratum reflection coefficient frequency spectrum of the logging data according to the acoustic wave time difference and the density curves of the plurality of logging points; determining a filtering operator frequency spectrum according to the stratum reflection coefficient frequency spectrum of the seismic data and the stratum reflection coefficient frequency spectrum of the logging data; performing convolution processing on the original seismic data according to the filtering operator frequency spectrum, and dete
