Magnetotelluric Inversion Method Based on Layer Constraint

摘要

At present,most of magnetotelluric inversion methods are based on the purpose of obtaining smooth geoelectric model,and the model parameter is uniformly modified at the same time or it is modified according to different weight factors,which is lack of pertinence to a certain degree.In order to obtain a clearer geological interface,aimed at the problem of difficultly selecting the modified parameters correction of magnetotellurie inversion model,in this paper,we propose an inversion method based on layer constraint.This method put forward to applying constraints of some or all layers.When we modify the model parameters,the model parameter is adjusted by constraints.This paper elaborates the implementation process of magnetotelluric inversion method that is based on layer constraint,the result of the calculation and analysis of examples shows this method is effective.
