According to the core data, the characteristics of resistivity variation under different porous structure and wettability are studied and explained theoretically. It is concluded that with the increase of porous structure exponent m, the resistivity increases significantly with the same saturation, and the influence is beyond imagination. With the increase of saturation index n, the resistivity increases with the same saturation. If all fixed m and n values are used to calculate the water saturation of the reservoir, the water saturation result will be very high and the hydrocarbon reservoir will be ignored. This change feature is of great guiding significance to the identification of hidden oil and gas reservoir satisfying the atypical Archie formula. |
