海洋可控源电磁法正反演及应用研究进展
Progress in research on the forward and inversion and its application of the elec-tromagnetic method for marine controllable sources
摘要
Abstract
Marine controlled-source electromagnetic method(MCSEM)is an important technique in seabed resource exploration.This method overcomes the shortcomings of natural field electromagnetic methods,such as weak signals and insufficient high-frequency information,and offers advantages such as wide detection range,high efficiency,and low cost.Therefore,it shows great potential in seabed resource and energy exploration.This paper first provides a brief review of the working principle and technological development of the MCSEM method,then focuses on the latest research trends in three-dimensional forward and inversion numerical simulation,elaborates on the forward and inversion methods of MCSEM,among them,geologically-guided or seismically-results-guided marine electromagnetic inversion or joint inversion can reduce the inversion multiplicity and be more advantage-ous than a single inversion observation data in geological interpretation.and presents application examples of the method in seabed oil,natural gas hydrates,and polymetallic mineral exploration.Based on the current state of re-search,this paper proposes key directions for the future development of MCSEM:improving the computational precision and efficiency of algorithms,conducting in-depth studies on three-dimensional anisotropic forward and inverse models,and enhancing data processing techniques.These strategic suggestions aim to promote the continu-ous advancement of marine electromagnetic technology and provide theoretical support and practical guidance for precise seabed resource exploration.关键词
