SIMULATION OF ELECTRICAL PROPERTIES OF ROCK SATURATED WITH MULTI-PHASE FLUIDS USING LATTICE GAS AUTOMATION
饱和多相流体岩石电性的格子气模拟

We use lattice gas automation to simulate the electrical transport properties of saturated rocks by computer with different water saturation and porosity, grain shape of matrix. The result shows the nature of non-Archie relation between resistivity index and water saturation. Saturation exponent n is not a constant as the traditional idea expected but a function of water saturation and porosity. It is a reflection of complexity-change rate of conductive path with water saturation. A new method is presented in this paper to calculate water saturation. The high efficiency of this method can be proved by comparing calculated result with rock experiments in field application.
