METHOD OF CONSTRUCTING GEOELECTRIC SECTION BY METHOD OF REFLECTED ELECTROMAGNETIC WAVES OF COMMON DEPTH POINT (MREMW-CDP) Russian patent published in 2025 - IPC G01V3/12 G01V3/38 G01S13/89 

FIELD: physics; mining.

SUBSTANCE: invention relates to geophysical prospecting by deep georadar and is meant for studying the structure and electrophysical properties of geological layers, elements, mineral resources, as well as for detecting inhomogeneities and anomalies. Disclosed is a method of constructing a geoelectric section by the method of reflected electromagnetic waves of a common depth point (MREMW-CDP), which includes carrying out radar probing, based on recording the dependence of the electromagnetic response of the medium on the distance between the receiver and the source to obtain results of wave interaction, recording of hodographs of reflected electromagnetic signals, performing speed analysis of hodograph data with determination of vertical distribution of the effective speed of the electromagnetic signal and plotting a time section. Method also includes conversion of time section into depth section with production of vertical distribution of interval velocities of electromagnetic signal in depth, recalculation of the electromagnetic signal velocity interval values into the dielectric permittivity (DP) and specific electrical resistivity (SER) interval values, construction of geoelectric section in the form of distribution of interval values of relative dielectric permeability (DP) and specific electric resistance (SER) by depth.

EFFECT: obtaining a detailed description of the electrical properties of the section – vertical distribution of electrical parameters (interval speed, DP, SER) without drilling and without the need for prior geological information and use of inversion methods.
