摘　　要：依据实验资料,研究不同注入水矿化度和岩石岩性、物性对孔隙度指数M、饱和度指数N的影响,建立了动态变化的M、N值与溶液电阻率(R_(wz))之间的解释模型。在此实验研究的基础上对阿尔奇方程进行修正,提高了油田不同注水开发期剩余油饱和度的解释精度,为油田开发测井解释提供了新的理论依据。Based on experiment data,studies on effects of salinity, lithology and physical property of different injected water on dynamic porosity exponent (M) and saturation exponent (N) are performed,and an interpretation model between the dy- namic M and N values and the solution resistivity is estab- lished.After the modification by Archie Equation,the inter- pretation precision of saturation of remaining oil at different waterflooding periods is highly enhanced.
