Abstract: Prestack reflection events cannot be flatten by conventional velocity analysis and NMO,statics correction, due to anisotropy and heterogeneity of the subsurface media. This is a difficult problem for AVO attribute analysis and prestack inversion. Based on shape context and dynamic time warping(SC-DTW),a new method of prestack residual moveout correction was introduced and verified by numerical simulation(model)and example analysis. The results show that the residual moveout correction method based on SC-DTWprestack gather has better anti-noise capability,better robustness to seismic waveform distortion,and can effectively eliminate the residual moveout of prestack seismic traces. The continuous waveform of the seismic events and the amplitude characteristics are not changed,which can improve the accuracy of seismic data processing and interpretation,such as AVO attribute analysis and prestack inversion. Using waveforms similarity of prestack gathers,the method optimizes for a reference trace,and run SC-DTW calculation of each trace with reference trace in calculation window, to calculate the dynamic warping path and residual moveout correction. The utility model has better practicability and popularization value.
