The present invention relates to the field of geological exploration seismic data processing method and particularly relates to a non-consistent time-lapse seismic bin matching method based on wave field continuation compensation. The overall scheme comprises a step of analyzing the bin sizes of first period data and second period data, and making a compromise treatment according to the bin positions and sizes of two periods, a step of carrying out rarefying treatment on the data with a smaller bin such that the data satisfies an intermediate bin size, and a step of carrying out gather compensation treatment on the data with a larger bin such that the data is matched with the intermediate bin size, wherein a 3D wave field continuation method is employed by the gather compensation treatment, firstly the seismic data is subjected to Fourier transform, then a spectral domain is subjected to the interpolation between shot gathers, and then the Fourier transform is carried out to obtain a compensated shot gather record. Compared with a conventional bin matching technology, according to the non-consistent time-lapse seismic bin matching method based on wave field continuation compensation, the data information of two periods are fully utilized, and good time-lapse seismic analysis and identification effects can be obtained.
