Application of catastrophe theory in identifying geological anomalous bodies with Seismic Data
Fengkui Zhang · Progress in geophysics · 2009
Point catastrophe theory is detailed in this paper. The point catastrophic model is described here. And the seismic signal is transformed into the standard form of cusp catastrophe by establishing the cusp model. The parameters of catastrophe, such as time-domain catastrophe potential, time-domain catastrophe time, layer catastrophe degree, frequency-domain degree and so on, are used to study real seismic data interpretation and test the feasibility of the theory. The results show that the position of abnormality of the catastrophe parameter profile or curve is related to the location of the geological anomalous body. It is effective to automatically pick up geology information and improve the precision of interpretation in seismic data. The catastrophe theory will provide a potential method for seismic interpretation.
