地震走时与重力数据的联合反演

A review of cooperative inversion using seismic travel time and gravity data

对目前的地震走时与重力数据联合反演发展进行了简要的概述。首先,从两类数据单独反演的基本原理出发,对两者进行了分析比较,并由两者参数间存在的相互关系,可将两类数据归并、统一到一个系统,合理地进行联合反演。其次,根据目前国内外的相关研究,介绍了当前联合反演的两种算法:依次反演和同时反演。最后,对联合反演中存在的问题进行了讨论。

In this paper, we made a review of cooperative inversion using seismic travel time and gravity data. At first, we analyzed the similarities and differences between the seismic travel time inversion and gravity inversion. For the empirical relationship between velocity and density, we may unify the two different data and do cooperative inversion. Then, we introduce two basic cooperative inversion algorithms： sequential inversion and joint inversion. And finally, we made a discussion on the problems in the cooperative inversion.
