The invention discloses a seismic data processing method and device. The method comprises the following steps: acquiring transverse wave data and longitudinal wave data in seismic data; performing pseudo sampling processing on the transverse wave data and the longitudinal wave data to obtain the transverse wave data and the longitudinal wave data after pseudo sampling processing; the pseudo sampling processing is used for modifying a sampling interval value in a trace head and a rolling head of a data head block of the transverse wave data and the longitudinal wave data into a preset value; explaining velocity spectrums corresponding to the transverse wave data and the longitudinal wave data after the pseudo sampling processing to form a corresponding relation between time and velocity of the pseudo sampling processing data; and carrying out velocity analysis processing, residual static correction iteration processing and time domain imaging processing on the seismic data according to the corresponding relati
