The results of laboratory experimental studies of the relaxation of the DC-induced polarization in saturated sand models of sedimentary rock are presented. The experimental methodology was based on registering of the relaxation IP signal (amplitude and time value) after a relatively long time of DC excitation (2-15 minutes). Depending on the chemical composition and petrophysical parameter of a rock such as the type of saturated medium (oil, electrolyte), the mechanism of polarization is different. The amplitude-time parameters of the relaxation signals depend on the petrophysical properties of the solid phase, on the salinity of porous medium, type of pore fluid and the electric field characteristics (current intensity and voltage). The Author describes the effective electrophysical characteristics of a porous medium by using well known equations. The obtained results suggest possibilities of inventing new methods in geophysical prospecting. The above experiments were the first step in this series and will be continued in the future.
Artykuł przedstawia wyniki badań laboratoryjnych nad procesami relaksacyjnymi WP (wzbudzonej polaryzacji stałym prądem elektrycznym) w nasyconych piaskowych modelach skał osadowych. Rejestrowano amplitudowoczasowe charakterystyki relaksacji sygnałów WP po stosunkowo długim czasie wzbudzenia prądem stałym (2-15 minut). Pokazano, że w zależności od składu chemicznego oraz rodzaju nasycającej cieczy porowej: ropa naftowa, elektrolit . mechanizm depolaryzacji jest inny. Amplitudowo-czasowe charakterystyki sygnałów relaksacyjnych zależą od petrofizycznych właściwości fazy stałej, rodzaju płynów porowych i właściwości pola wzbudzającego (natężenie przepływającego prądu i napięcia). Zostały teoretycznie opisane efektywne elektrofizyczne charakterystyki porowatego ośrodka. Uzyskane wyniki sugerują możliwość utworzenia nowej metody geofizyki poszukiwawczej. Powyższe eksperymenty były pierwszym krokiem z tej serii i będą kontynuowane w przyszłości.
