The embodiment of the application provides a seismic data processing method and apparatus. The method comprises: seismic data of a target area are obtained; a first seismic wavelet is extracted from the seismic data; the first seismic wavelet in a time domain is compressed to obtain a second seismic wavelet; according to the seismic data, the first seismic wavelet, and the second seismic wavelet,an inversion objective function is established; and processed seismic data are determined based on the inverse objective function. Because the processing method and apparatus are based on the inversion principle and the processed seismic data with high resolution are obtained based on the inversion objective function, unstable data processing caused by an inverse wavelet operator is avoided, technical problems of low accuracy and low reliability of seismic data processing in the prior art are solved, and a technical effect of acquiring preserved-amplitude high-resolution seismic data stably isrealized.
