Joint inversion of magnetotelluric and gravity data based on petrophysical property

摘要

The aim of joint inversion is to improve the reliability of inversion results and to reduce the non-uniqueness of inversion as the current research hotspot in geophysical field[1].In the practical work,lateral resolution of MT method is weak while it’s vertical resolution is better.And the lateral resolution of Gravity method is better than MT’s.MT-Gravity joint inversion can improve the vertical resolution and transverse resolution at the same time [2].In joint inversion field,the one on the basis of petrophysical property between different physical methods to implement is one of the hot spot of research in the field.
