Abstract：In response to the problem of susceptibility to environmental interference and failure to consider time continuity in the magnetotelluric inversion method,in this paper,time constraint item was added after traditional objective function to carry out the research of time-lapse magnetotelluric simultaneous inversion method based on Tikhonov regularization theory,then the results of independent inversion and simultaneous inversion were compared through panel data model.The results shows both inversion methods can reflect the position information of anomaly body,but the simultaneous inversion method can effectively improve the ef-fect of missing data on inversion results,and the change process of reservoir resistivity is more continuous.It is found that more accurate inversion results can be obtained through the utilization of observation data in each time step in simultaneous inversion method.
