Abstract: Flooding process enlarges the porosity and air-permeability of reservoir,but it doesn't change the relations between them and their log response.The result of rock resistivity experiment on simulated flooding process indicates that the parametersbandnof Archie equation are not constants,and the changing of parameterFis not only because of the difference of the function of pore structure,but also the change ofRwin water flooded zone.Unified Archie equation established on this base may be adapted to all stages in the flooding process.The linear model of water cut vs.water saturation makes it possible to analyze the relations of reservoir and fluid characteristics with water-cut.Unified water-cut equation established on this base may be adapted to describe the flooding process.Such unified equations have a theoretical and more practical value.
