Analysis Method Of Seismic Data In Time Domain And High Resolution Processing Technique

First the paper introduces the frequency analysis of design ideas and all the linear relationship between the methods of frequency analysis, advantages and disadvantages. By introducing short-time fourier transform, wavelet transform and S transform(including generalized S transform) the concept of comparative advantages and disadvantages of three kinds of transformation during the seismic data analysis.By S transform detail, clearly show the advantages of S Transform: fourier Transform it has a direct contact, non-destructive reversible, but also a linear time-frequency representation; S can transform a good balance between time and frequency resolution. Because of these advantages of the S transform text on its basis of generalized S transform has been improved and simplified, improving the generalized S transform in signal processing flexibility and practicality and accuracy of data processing.According to seismic wave propagation in inhomogeneous medium, the introduction describes seismic wavelet degeneration dynamic convolution model is proposed based on dynamic deconvolution of seismic data generalized S transform method. The main idea is to conventional static wavelet fourier transform, the numerical value of the complex reflection coefficient of the formation of generalized S transform decay product family function, when non-stationary signal after generalized S transform spectrum to be replaced.Dynamic deconvolution method can improve the resolution of seismic data based on generalized S transform seismic data, seismic wave energy also can be caused by the formation of the absorption attenuation compensation. The method is applied to the high resolution processing of the real seismic data and the extraction of the seismic instantaneous parameters.
