摘要：3D seismic exploration has become a common method for seismic exploration. Conventional 2D Radon transform for multiple attenuation is only applicable for seismic data acquired in a 2D manner and does not consider the characteristic of 3D pro-pagation of a seismic wave field. Therefore, it is not suitable for 3D seismic data processing. It is urgent to explore a processing algorithm for 3D seismic data. After the systematic study of 3D Radon transform for multiple attenuation, iterative threshold shrinkage is adopted to improve the resolution of the 3D Radon transform domain. Consi-dering the characteristic of amplitude versus offset, orthogonal polynomial transformation is introduced to fit the amplitude variation of seismic data in different curvature directions. The results of synthe-tic data and real data show that the 3D high-precision amplitude-preserving Radon transform can achieve high-resolution data in the model domain and, effectively separate primaries and multiples. Moreover, the polynomial fitting can protect the amplitude of effective waves. The proposed me-thod enables multiple attenuation with high fidelity. ? 2022, Editorial Department OIL GEOPHYSICAL PROSPECTING. All right reserved.
