Research methods of geological structures over hydrocarbon accumulation

Abstract

The article presents the results of research methods of geological structures over hydrocarbon accumulation. Measurements of the characteristics of these structures at the Geological hydrocarbon accumulation of the Republic of Belarus are made. Irradiation with a dual-frequency electromagnetic wave and reception of the reflected wave in modes with the low-frequency signal exceeding 10 times the highfrequency signal and the high-frequency signal exceeding 10 times the low-frequency signal were used. It has been established that measurement of reflection coefficient contrast between a geological structure and a homogeneous underlying profile increases the accuracy of hydrocarbon isolation. Methods of hydrocarbon deposit search based on the measurement of phase components of surface impedance in the mode of amplitude-frequency-modulated signals and determination of reflective properties of the medium over hydrocarbon accumulation in the mode of dual-frequency signals have been developed. The data of the obtained studies can be used to develop methods of hydrocarbon deposits detection.
