摘　　要：借助于多元线性拟合,根据油田生产动态数据,推导出油水相对渗透率与含水饱和度的定量关系式。实例分析表明,利用该计算方法得到的相渗曲线能够更好地反映油藏的整体特性,该计算方法可对油藏的含水上升规律做出较准确预测。Oil-water relative permeability data is indispensable for calculating development parameters,which makes dynamic analysis and numerical reservoir stimulation,so it is critical to obtain relative permeability data effectively.The relative permeability curves obtained by laboratory experiments in oil industry can not properly reflect reservoir integrity attributes and present measured deviation because of the impact of formation heterogeneity and core pollution during coring.Therefore,a new method should be considered to resolve it.Combined with field performance data,the research based on field performance data and linear fitting can acquire the relationship between oil-water relative permeability and water saturation.After studying field case,this paper gets justifiable relative permeability curve by theoretical calculation which can reflect reservoir integrity attributes,then based on it,water holdup can be predicted.
