大地电磁与地震联合反演研究现状与展望
|
摘要
由于大地电磁探测和地震勘探各自存在优势和局限,因此联合反演比单独一种地球物理资料反演更优越.本文剖析了联合反演的两类分类方法,指出大地电磁与地震方法具备联合反演的基础-理论上相似,物性上有联系,并重点分析国内外大地电磁与地震数据联合反演的研究现状与存在问题,总结层状均匀和非均匀两种介质结构的电震联合反演算法.对于如何耦合不同类型的物性参数这一联合反演的核心问题,指出目前广泛使用的岩石物理法和结构法两类方法的适用范围.最后提出大地电磁与地震联合反演的发展方向:层状均匀介质结构要优化线性迭代技术;非均匀的复杂地质结构,需加紧非线性反演理论向非线性反演发展,其中结构法反演前景广阔,要加强实际资料的运用;此外,电震联合反演也需与岩石物性等先验地质信息相结合.
Considering the advantages and limitations of magnetoelectrotelluric detection and seismic exploration,this paper states joint inversion more superior than a single geophysical data inversion.Two kinds of classification methods of joint inversion are analyzed,and the foundation of joint magnetoelectrotelluric and seismic inversion is pointed out,including the similar in theory and the relations on physical property.This paper surveys the research status and existing problems of joint inversion with magnetoelectrotelluric and seismic at domestic and overseas,and summarizes its two algorithms in homogeneous and heterogeneous medium.As the key of joint inversion is to coupling of two different physical property parameters,we discuss the applicability of rock physical method and structure method which are widely used.At last,we propose on joint magnetoelectrotelluric and seismic inversion.Linear iterative technology must be optimized in homogeneous medium,and nonlinear inversion theory need step up to the nonlinear inversion practice in complex geological heterogeneous structure.As structure method inversion has broad prospects,the actual data utilization needs to strengthen.It is also necessary to combination geological information including rock physical property on joint magnetoelectrotelluric and seismic inversion.
