油水相对渗透率曲线在油气田开发中具有非常重要的作用，可以利用其分析油井产水规律，计算油井产量、流度比和确定储层中油水的饱和度分布、油水接触面位置等。目前相对渗透率曲线主要由实验室测定，然而由于储层的非均质性、实验条件等的限制制约着相对渗透率曲线的精度。本文基于分形理论，利用某海上油田实际历史生产数据计算得出了油水两相的相渗曲线，并结合实验室测试数据，证实了该方法的可靠性。

The oil-water relative permeability curve is of great importance in the field. It can be employed to analyze water-producing law of oil wells, as well as calculate oil production and mobility. It can also be utilized to determine oil/water saturation distribution and locate oil and water interface, etc. However, relative permeability curve is mainly obtained by laboratory tests, the precision of that is limited to reservoir heterogeneity and experimental conditions. Based on the fractal theory, this paper takes a certain offshore oilfield as example and calculates oil-water relative permeability curve according to production data. A combination of test data proved the reliability of fractal theory.
