On the basis of the actual high-precision seismic data in Yongxin area, by the degradation processing on the divisible-bin geometry, eight geometries were selected which had relatively even fold and better properties and could be deployed in the field, the authors utilized frequency spectrum estimation method to carry out analysis and statistics on SNR under the conditions of same bin with different fold, different bin with the same fold and different noise background, studied the relationship of fold and SNR. The results show that: the SNR is related to fold and almost has nothing to do with bin size; 2) the SNR of different seismic data is the same if the fold is the same; and 3) the fold of high-precision 3D seismic data should be about 200.
