Реферат: The present study investigates the influence of wettability on the hysteresis of electrical parameters through numerical simulation of drainage and imbibition processes. Using a three-dimensional digital sandstone sample and numerical algorithms for simulating two-phase filtration and electric current flow, a series of numerical experiments are conducted over a full range of contact angles. The dependence of the resistivity index on the water saturation is then established for each value of angle, and the parameters of Archie’s law – namely, the saturation exponent and the saturation distribution factor – are estimated. The principle objective is to derive functional relationships between these parameters and the contact angle. The resulting dependencies are constructed as piecewise linear functions, exhibiting different trends for drainage and imbibition. Validation at intermediate contact angles revealed that the relative errors of the estimates remain below 3%.
