Pei Zhenglin, Yu Qinfan, Mou Yongguang.Genetic evolution tomography of multiwavelet seismic waveforms in multi-scale wavelet analysis.Geophysical Prospecting, 2 0 0 2, 37 (3): 2 37 ~ 2 4 2 Cross-well seismic waveform tomography is A very complex non-linear inversion problem. In this paper, we propose a wavelet multiscale cross-well seismic genetic evolution tomography method. The genetic algorithm is improved by using two-dimensional real coding, velocity gene block mutation and multi-scale wavelet transform, which greatly accelerates the search of operator Speed, improve the stability of the algorithm and global optimization. The numerical model test results show that the imaging method has high resolution and good image quality, and has good application prospect.
