通常实验室会提供若干条各不相同的相对渗透率曲线，然后进行平均相对渗透率曲线的标准化处理，得到具有代表性的相对渗透率曲线。然而目前各方法标准化结果几乎没有学者将其与实际油田开采特征及油水运动规律结合起来，评价方法的合理性。针对该问题，文中结合实际油田生产动态，从含水上升规律、驱油效率及采收率3方面对各方法标准化结果进行分析研究，结果表明，多条曲线平均标准化方法确定的油水相对渗透率曲线更符合实际油藏渗流特征。

A lot of different relative permeability curves are provided from the laboratory. The representative relative permeability curve is obtained by standardized processing. However, no one correlates the result of each method with the production characteristics and oil-water movement law of actual oilfield to illustrate the rationality and validity of the each method. According to the problem, we study the standardization results of each method combining with the actual field performance and from the water cut rising rules, oil displacement efficiency and oil recovery. Results show that the relative permeability curve determined by the standardized curve method of mean curve is in accord with the seepage characteristics of actual reservoir.
