Abstract
The phase characteristics of the surface impedance of the medium above hydrocarbon deposits were studied in the mode of their interaction with amplitude-frequency-modulated signals. The characteristics of the geological profile above oil and gas deposits were investigated depending on the carrier frequency, modulating frequency and modulation index. The rationale for using sounding with amplitude-frequency-modulated signals for practical implementation in order to increase the information content and accuracy of determining hydrocarbon boundaries was provided. A method for geoelectric exploration was developed to determine hydrocarbon boundaries using amplitude-frequency-modulated signals based on measuring the phase characteristics of the surface impedance of the medium above the deposits. The results obtained can be used for exploration geophysics in order to detect oil and gas deposits.
