FIELD: geophysical exploration.
SUBSTANCE: invention relates to the field of geophysics, namely to geophysical methods for prospecting and exploration of mineral deposits, and can be used for the study of fluid-saturated rocks. A method for geoelectric exploration is claimed in which the electrical characteristics of the rock are recorded along the wellbore, including apparent electrical resistance, natural and induced polarization of the rock, while for each measurement point the following values are recorded: the values for these characteristics without acoustic and electromagnetic effects on the rock; the values for these characteristics under acoustic influence on the rock; the values for these characteristics under the influence of alternating electric current on the rock; the values for these characteristics taking into account acoustic and electric current effects on the rock; then the physico-chemical properties of the rock at each measurement point based on the differences in values for the characteristics of the rock recorded at one measurement point are determined. Unlike the prototype, the lower limit of the acoustic impact frequencies is chosen from the infra-low range, and the upper limit is no more than 1000 Hz.
EFFECT: increase in the information content of the results of geoelectric exploration.
