摘要：
Nonlinear seismic waveform inversion problem is very important and difficult in oil geophysical prospecting field. In this paper, multiscale seismic waveform inversion by wavelet transform is proposed. For 1-D nonlinear seismic waveform inversion problem, wavelet, transform method is compared with direct iterative method and multigrid method. Numerical results demonstrate that this method is more efficient.
