| Popis: | This work describes the basic approaches to the solution of three-dimensional (3D) problems of geoelectromagnetism with the use of the finite element method and the possibilities of the GeoEM program complex for its implementation. The methods of modeling geoelectromagnetic fields for the most widely known types of controllable sources and the mathematical apparatus for the solution of problems of magnetotelluric soundings are considered. Examples of the calculations of 3D fields for the horizontal and vertical electric lines in planning electric exploration works on the shelf are presented, as well as an example of the 3D interpretation of array transient electromagnetic sounding data during the search for deep-seated target objects in conditions of a mostly heterogeneous upper part of the section. |
