Multi-scale singularity detection and its application to seismic facies analysis
多尺度奇异性检测及其在地震相分析中的应用

This paper discusses the singularity of seismic trace. WTMMLA (wavelet transform modulus maxima line amplitude) can been extracted along WTMMLs (wavelet transform modulus maxima lines) of seismic traces by virtue of wavelet transform. This attribute embodies the essential characteristics of seismic signal in the time-frequency domain and can be used to differentiate from two adjacent seismic traces easily. Therefore, based on the singularity, a new method of seismic faceis analysis is proposed integrated with Kohenon net. This technique has been tested on the theoretical model and then successfully applied to the practical data. This approach has not only succeeded in seismic facies analysis, but also has some ability of tolerance with the horizon interpretation.
