Determination of the parameters of conducting two-dimensional objects with isometric cross section according to magnetic variation in the profile data
When interpreting magnetotelluric profile data, as with other geophysical methods, a problem of accounting for inhomogeneities outside the profile arises. In this case, the analysis is an important tool for data of magnetovariational profiling (MVP). Measurements were performed simultaneously with IMP magnetotelluric sounding (MTS). This is done by adding a single channel to measure the vertical component of the magnetic field (Hz). The combination of MTS and the IMP significantly increases the possibility of excluding the anomalous bodies at the side of the profile. The authors are determined to define the parameters of 2D conductor, located in the side of the profile of the observations and parallel to the profile. Two-dimensional modeling was performed using the software package WinGLink (Geosystem). Studies have shown that if the distance from the profile to the axis of conductors is known, the depth of the upper edge is determined by the frequency characteristic of the tipper. The step-by-step method for determining the depth of the anomalous object is presented. The proposed method will help avoid gross errors in interpretation as well as form an informed model for 3D- modeling.
