In this paper,a multiscale total variation method is applied to parameter identification problems for time-lapse seismic which consists of two or more seismic surveys shooting at different calendars.For the discontinuous parameters,a total variation regularization method is introduced instead of the traditional Tikhonov regularization.Combined with a multiscale method,a multiscale total variation regularization method is put forward to improve computational efficiency and accuracy.In numerical simulation,the multiscale total variation regularization method is compared with both the multiscale-Tikhonov regularization method and a single scale total variation regularization method for time-lapse seismic inversion.The numerical results show that the proposed multiscale total variation method is more stable,faster and more accurate than other methods.
