Practical Testing of a Method for Recording Hydrocarbon Boundaries Based on Measuring the Deposits’ Own Radiation

Abstract

The article provides a theoretical analysis of the interaction of dual-frequency and modulated electromagnetic waves with anisotropic media above hydrocarbon deposits and computer modeling. The frequency range of changes in the electrodynamic parameters of the environment above the deposit with the manifestation of anomalies in the electric field strength has been established. Recommendations are given for the use of modulated signals to improve the accuracy of determining the boundaries of hydrocarbons based on measuring the phase characteristics of the surface impedance of the medium above the hydrocarbons. A hardware and software complex has been developed for recording the electric field strength in the modes of receiving probing signals and the natu ral radiation of hydrocarbon deposits. Experimental studies were carried out in gas fields of Syria. Methods are shown to increase the information content of the developed method and equipment when carrying out prospecting work at hydrocarbon sites. The research results can be used in devices for identifying oil and gas deposits in geophysics.
