Research on dynamic deconvolution and its effect analysis

The current common deconvolution methods are based on the conventional convolution model,in which before de- convolution,the amplitude compensation has to be per- formed for the attenuation seismic channel.Therefore,it is limited to enhance the seismic resolution.In the conventional convolution model,it is supposed that the wavelet amplitude do not attenuate in the spreading process.But,in fact,the wavelet attenuates gradually,so it is necessary to establish a convolution model to describe the dynamic transmission.In the theory of dynamic convolution,the seismic resolution can be obtained without conducting the amplitude compensation for the attenuation seismic channel.In contrast with spike deconvolution,the dynamic deconvolution functions appar- ently in the followings:1)to enhance the seismic resolution; 2)to compensate the amplitude attenuation due to absorp- tion.Analysis on theoretical model and calculation of case studies validate the method of dynamic deconvolution.
