Blind Extraction Technology of Independent Spectrum Component Based on Generalized s Transform
Zedong Zhan · Journal of Oil and Gas Technology · 2011
Generalized S transform had good time-frequency focusing property,and it could be used to obtain the single-frequency data volume for studying the stratum information characteristics.But the overmuch single-frequency data volume would cause inconvenience to seismic data analysis.In additional,if signals were too close or even overlay,it would create difficulty for signal research.The algorithm based on the blind signal processing can extract some effective independent frequency spectrum components distinguishing with the useful characteristic information of seismic profile from the numerous single-frequency data volume.On the basis of simulation test,the method is applied in Triassic in TH Area.It is contrasted with other related analyses,it is confirmed that the method is validate.
