【Abstract】 The paper shows how to construct a parent wavelet function based on Bubble function according to feature of seismic event and fault. After using Gauss function as a parent function, a 2 D wavelet analysis has been conducted from seismic data and edges information of seismic event has been detected, which became a two valued image by two valuedness, then joint component with small extension (noise) has been deleted from the picture using CB shaping filtering. Theory and real data showed that the technique has excellent result.更多还原
