Accurately predicting the water production rate of multiple-phase fluid flows through porous rock is important to many engineering and geological applications. Taking into account the irreducible water and capillary tortuosity, the equivalent rock element model of previous results has been improved. Based on the improved capillary equivalent rock element model, this study proposes a relationship model between the water production rate with two-phase fluid and the resistivity index. The relationship model is verified using rock samples, and the result shows that the water production rate calculated by the new model closely aligns with experimental values and parameter calculation accuracy is improved. And, applications of the new model to well logging data show that the calculated water production rate is consistent with the actual production situation. It is more efficient and accurate in reservoir evaluation. The new model provides a new idea for the study of rock seepage characteristics with multiple phase fluids.
