Abstract

Summary

In the situation of thin-interbed reservoirs, the common seismic deconvolution can’t effectively improve the resolution because of the impractical assumptions of white noise to reflectivity and zero phase or minimum phase to seismic wavelet. In the paper we propose a method of seismic deconvolution which can improve the resolution obviously. Firstly we estimate the wavelet accurately based on the fourth-order cumulant and without these impractical assumptions. Then use the estimated wavelet to construct the shaping filter operator by the least-squares method, at last apply the shaping filter operator to seismic deconvolution and improve the resolution. The synthetic example and some real data results show the method can obtain the deconvolution result more closer to the reflection coefficients, and the recognition of thin-interbed reservoirs is enhanced obviously.
