摘要:
以碳酸鹽巖為主體的復雜儲層,其多元的孔隙結構和強烈的非均質性導致經典的阿爾奇方程產生非阿爾奇特性。基于2 028塊巖心巖電實測數據,結合三維數字巖心微觀數值模擬,深入分析組成碳酸鹽巖多元復雜孔隙空間的不同“元素”(基質孔隙、裂縫與溶孔、洞)各自的導電特性及其對m、n值的影響,闡述了它們的分布特點和變化規律。認為碳酸鹽巖m值的分布與變化雖然是多種影響因素的交織,但主要受巖石孔隙結構控制,其物理意義在于表征孔隙結構對巖石導電性的影響,可定義為孔隙結構指數。在影響碳酸鹽巖n值變化的諸多因素中,主導因素是巖石的潤濕性,導致巖石儲集空間油氣微觀分布狀態的差異性。n值的物理意義在于表征與描述微觀孔隙中油氣分布狀態的差異性對巖石導電性的影響,應定義為油氣飽和度微觀分布狀態指數(飽和度指數)。在此基礎上,為拓展阿爾奇方程在碳酸鹽巖等復雜儲層的應用提出可行的思路與方法。
Abstract:
A nonArchie phenomenon, where the saturation exponent varies with the water saturation, has been observed for carbonate rocks. It is caused by complicated pore structure and heterogeneity in texture. It is critical to explain the nonArchie phenomenon exactly and find out how to modify it. We assume the pore space of carbonate is composed of different kind of elements, such as matrix pore, fractures, vugs. The effect of pore space elements on the value of m and n were studied by numerical simulation of electrical conductivity of carbonate based on 3D digital cores and experimental electrical measurements of 2 028 carbonate samples. The results indicate that the value of m for carbonate reservoir is dominated by the structure of pore space. The parameter of m describes the effect of pore space on electrical conductivity of carbonate. So it can be defined as exponent of pore structure. Many factors have effect on the value of n. The wettability of rock has the greatest impact on the value of n because the wettability determines the micro distribution of oil (or gas) in pore space. The value of n is to describe the effect of pore fluid distribution on electrical conductivity and can be defined as exponent of saturation. A new method is proposed to modify the Archie’s equation in order to apply it directly to complex carbonate reservoir.
