Determination of reflection coefficient contrast in medium over hydrocarbon accumulation

Abstract

The article analyses the method of searching for hydrocarbon accumulation on the basis of determining the reflection coefficient contrast. Experimental research on hydrocarbon accumulation of the Republic of Belarus is carried out. Was used a method for estimating the reflectivity of the medium over hydrocarbon accumulation under the influence of electromagnetic waves with linear polarization based on the contrast of reflection coefficients between the measurement points of the investigated profile and the calibration measurement point located outside accumulation. The anomalous behaviour of the reflection coefficient contrast was found to correspond to the hydrocarbon boundary. The results of experimental research confirmed the increase in the accuracy of determining the boundaries of hydrocarbon accumulation based on the method of determining the reflection coefficient contrast. The obtained research results can be used in exploration geophysics.
