基于归一化局部互相关算法的相位编码全波形反演
The Phase-Encoded Full Waveform Inversion Based on Normalized Local Cross-Correlation Algorithm
摘要
Abstract
In this paper,a method of phase-encoded full waveform inversion based on normalized local cross-correlation algorithm is proposed,which can discribe the correlation degree of modelled seismic traces and actual seismic traces in each time window,so the method is more suitable for the phase-encoded full waveform inversion of unilateral observation seismic data since the residual record can reflect the effect of velocity model perturbation on wave field accurately,Numerical experiments show that:the normalized local cross-correlation algorithm can more effectively suppress the observation residuals in the residual record of unilateral observation seismic data compared with the normalized global cross-correlation algorithm,and the inversion accuracy of full waveform inversion based on normalized local cross-correlation algorithm is obviously better than that of full waveform inversion based on normalized global cross-correlation algorithm,so it is expected to play an important role in waveform inversion of actual data.关键词
