Oil\|water relative permeability is one of the most basic input data of the reservoir numerical simulation, and also an important parameter to effect produce of oil and water. In this paper, we discussed how to choose an oil-water relative permeability curve in the region with no core data. Here, FZI index (Flow Zone Indicator) as a standard was introduced to classify the flow unit. We draw the double logarithmic diagram of RQI and to determine whether or not the similar of petrophysical properties in target zones and core sampling areas existed to affect the fluid flow. If the petrophysical property for both areas is similar, then the relative permeability of samples can be used. The method can give more comprehensive information about reservoir porosity, permeability, and tortuosity to impact ability of fluid flow.
