摘要:

重震联合反演是多地球物理数据联合反演的重要分支.通过调研国内外重震联合方面经典和最新文献,从模型参数化、联合数据类型、反演的实现和结果评价、优势及应用等多个角度对重震联合框架和新进展进行了介绍.相比于单数据集反演,重震联合反演在减弱多解性、提高物性分辨率、提高成像质量、岩性分类和地质解释等诸多方面都具有独特优势.目前,重震联合方法和技术还处在发展阶段,在多类型数据的结合、反演及定量评价、加强实际应用等方面发展空间还很大.最后,提出了重震联合方面值得关注的几点问题和可能的发展方向.

Abstract:

Gravity-seismic joint inversion is an important branch of multi-geophysical joint inversion. By investigating the classic and latest literatures on gravity-seismic joint inversion at home and abroad, the framework and new developments of gravity-seismic joint are introduced from the perspectives of model parameterization, joint data types, inversion implementation and result evaluation, advantages and applications. Compared with single dataset inversion, combining gravity and seismic data into inversion has unique advantages in reducing multiple solutions, improving resolution of physical property and imaging quality, lithology classification and geological interpretation, and so on. At present, the methods and technologies for gravity-seismic joint inversion are still in the development stage, and there is still a lot of room for improvement on the combination of multi-type data, inversion and quantitative evaluation, and strengthening practical applications. Finally, some issues and possible directions worthy of attention in gravity-seismic joint inversion are proposed.

Key words: Seismic, Gravity, Gravity-seismic joint, Joint inversion, Application
