ON ASSOCIATION OF THE 1st KIND SEISMIC-ELECTRIC EFFECT AND PETROPHYSICAL PARAMETERS OF MEDIUM
V. V. Filatov, V. N. Savinov, O. Yu. Svetozerskiy
Manifestations of the first-order seismic-electric effect are investigated based on the results of rock samples physical modeling. The main attention was directly paid to studying processes of resistivity drop and relaxation resulting from elastic impact on a sample. It is noted that a parametrical resonance phenomenon causing a nonlinear response of the medium to acoustic excitement at different kilohertz frequencies takes place. Interrelation between seismic-electric effect characteristics and such parameters as porosity, jointing, and interval longitudinal and transverse velocities is established. It is noted that the first-order seismic-electric effect amplitude is connected with rock characters. It allows considering the intensity of seismic-electric effect as a quantitative characteristic in studying reservoir properties of the environment.
Key words: seismic-electric effect, rocks, physical properties, reservoir properties, rock characters.
