摘要
模型和实验研究证明,岩石润湿性对原油和地层水在孔隙系统中的分布有重大影响,因而能改变岩石电阻率、电阻增大系数和饱和度指数与含水饱和度的关系.在含水饱和度和地层、水电阻率相同的条件下,油湿和水湿岩石的电阻率相差很大。
Model and experiment studies have shown that wettability of a porous rock can strongly affect the distribution of formation water or oil in pore system,and change the dependence of resistivity,resistivity index and saturation exponent on water saturation.Resistivity of a oil-wet rock can be much higher than that of a waterwet rock with the same water saturation and water resitivity.This is of great importance to quantitative interpretation of electrical logging.
