摘要
不同的地球物理方法有各自的应用、优势和局限性,正是因为局限性的存在,单一地球物理方法在地球物理反演中具有一定的不足,例如反演精确度等,因此将多种地球物理方法进行联合反演要比单一方法反演具有一定的优越性.本文介绍了联合反演的分类方法,说明电磁与地震理论的相似性,以及物性上的联系,重点分析近几年国内外电磁和地震联合反演的研究进展、现状及存在的问题.对于不同类型物性参数在联合反演中的耦合问题,指出岩石物理方法适用范围.最后预测电磁和地震联合反演的发展方向,包括优化算法从线性到非线性,进一步到更高级算法;进行更多方法结合的联合反演;在维度上的拓展,一维到二维、三维,甚至四维.另外,加强联合反演岩石物性等先验信息的结合以及结构法反演前景广阔,需要进行更多实际应用验证.
Different geophysical methods have different applications,advantages and limitation,it is due to the limitation,there are some shortcomings in geophysical inversion by using only one geophysical method,such as the precision of the inversion and so on,so jointing various geophysical methods is better than single geophysical method. In this paper,we will introduce the classifications of the joint inversion,explain the similarity of the electromagnetic and seismic theories and the connection of the physical property,focus on the research development, present status and the existing problems of the joint inversion of electromagnetic and seismic,both in China and abroad in recent years. For the coupled problem of the different types of physical property parameters in joint inversion,we indicate the scope of application of the petrophysical method.Finally,we forecast the development direction of the joint inversion of electromagnetic and seismic,including the optimization algorithm from linear to nonlinear,even more advanced algorithm,the joint inversion with more methods,the extension of the dimensional space from 1D to 2D,3D so far as to 4D. In addition,it have broad prospects to enhance the combination of the prior information of the rock physical property in joint inversion and structure inversion method,but these need more practical applications to verify.
