A Discussion of Wavelet Shaping Based on Single-channel Seismic Survey
摘要
Abstract
In marine geology survey,high-resolution digital single-channel survey is an important method.Single-channel seismic usually adopts single-source to produce a wavelet.Based on this way,the source-wavelet appears a lot of sidelobe,which leads to the produce of a plenty of in-phase axis,thus affect the seismic interpretation.For suppressing the wavelet's sidelobe effectively,the paper uses homomorphic deconvolution to estimate wavelet,and dose wavelet shaping processing to improve the vertical resolution of the seismic by usingthe statistical wavelet.The feasibility of using homomorphic deconvolution to reconstruct the seismic wavelet is proved by the simulation experiment.In the end,it is shown in practice that the statistical wavelet has brought good application effect in wavelet shaping processing.关键词
