ANALYZING METHOD AND APPLICATION OF THE INSTANTANEOUSATTRIBUTES FOR THREE-PARAMETER WAVELET TRANSFORMATION
摘要
Abstract
In views of characteristics of the quickly changed amplitudes and frequency components in reflected seismic signals in thin formations, the new analyzing wavelet-three-parameter wavelet is studied and moreover on the basis of the transformation of the above wavelet, the method of calculating seismic instantaneous attributes within the facies space is presented. There are three adjustable parameters in the three-parameter wavelet, therefore there is greatly high freedom when analyzing the signals with the help of the wavelets, and furthermore the seismic wavelets or given effective signals can be much better matched; by comparing the three-parameter wavelets and BM-SW wavelet or other wavelets, there are much better partialized properties in the time domain. The actual practical effects show that there are greatly higher signal-noise ratio and resolution for seismic instantaneous attributes by three-parameter wavelet transformation comparing with the instantaneous attributes by Hilbert transformation. The analyzing method of seismic instantaneous attributes based on three-parameter wavelet transformation is an effective way to identify the sandbodies in thin formations.关键词
