Abstract:

In the process of geophysical exploration, observation data are limited and errors exist, leading to the presence of non-unique inversion results. In order to solve the problem of non-uniqueness, the authors study the mathematical theory of cross-gradient, and achieve the joint inversion of 2D magnetotelluric and first-arrival wave seismic traveltime with cross-gradient. At the same time, we establish two models. Through test of each model and comparison between the two models, it is proven not only that the result of the cross-gradient joint inversion is better than the single inversion in remediation on geometry and physical property parameters, but also that the cross-gradient is independent from the petro-physical properties. Further, the cross-gradient figure evidences the high similarity of the joint inversion models, and the cross-plot of joint inversion presents a better correlation with physical properties. These, in turn, prove the validity of the joint inversion.

Key words: magnetotelluric, first-arrival wave seismic traveltime, cross-gradient, joint inversion
