重磁电震联合反演研究进展与展望

重磁电震等地球物理勘探成果的联合反演是解决复杂地质问题所用的综合地球物理解释方法,是目前可信的定量的综合地球物理解释技术,是联合应用多种地球物理信息,通过反演地质体的岩石物性和几何参数来求得同一个地下地质和地球物理模型的技术.本文综述了从上世纪80年代以来,地球物理场联合反演技术取得的长足发展,主要表现在两个方面:一是在地球物理场综合应用基础上,发展了两两地球物理参数之间互为约束的反演的技术,二是是反映了联合反演计算方法的进步,如线性与非线性反演比较、反演方法选择等.综述了联合反演的思路与对策,提出了联合反演的发展方向.

Joint inversion of gravity-magnetic-electrical-seismic combination survey: progress and prospect

Joint inversion of explor production of Gravity-Magnetic-Electrical-Seismic survey is Integrated Geophysics interpretation method,it is integrated geophysics interpretation technique of only believable quantification at present,and it is combine application multi-geophysics information,through Inversion petrophysical property and geometric factor of geologic body get technique of one and the same underground geological and physical geography model.Text sum up development of Joint inversion technique of physical geography from the eighties of the 20th century,mostly represent a couple of side :the first to develop inversion technique at each other obligation of both parties of physical geography parameter on the basis of comprehensive applications of physical geography field.the second to advancement about joint inversion count methodological,for instance linearity inversion in contrast to nonlinearity inversion,choice of inversion means etc.sum up thought and countermeasure of Joint Inversion,put forward grow way of Joint Inversion.
