线性Radon变换在地震面波压制中的应用
Application of linear Radon transform in seismic surface wave suppression
摘要
Abstract
Strong surface wave of high amplitude,energy and dispersion property reduces the reflected signal to noise ratio of seismic record.In order to suppress the surface wave reflection record information,and improve the signal-to-noise ratio of the reflection data,this paper used the finite difference of several kinds of typical geological model for the forward modeling.With the help of linear Radon transform surface wave suppression for synthetic records,the curve velocity filtering is used to reduce Radon transform the endpoint effect and the effects of aliasing.Through a large number of theoretical model,using the Radon transform to suppress coherent noise in seismic data processing has good application and can effectively suppress the seismic surface wave interference.Finally,the actual seismic data linear Radon transformation method is applied to suppress the surface wave,and analyze the data after processing,better processing results are achieved.关键词
