摘　　要：随着油田开发的进一步深入,油藏属性参数变化规律及其变化机理的研究越来越重要.油水相对渗透率曲线是油水两相渗流特征的综合反映,是油藏数值模拟工作最基础的资料之一,如何准确认识、合理选取并处理油水相对渗透率曲线越来越得到重视.准确计算相对渗透率,确定相对渗透率曲线能够有效确定油气水在储油层中的分布、利用相渗透率资料分析油井产水规律.国外在研究方法和手段上取得较大进展,相对渗透率计算方法主要分为分析法、半分析法和历史拟合法3类,分别具有优缺点,对中国一些经过长期注水开发的成熟油田后期开发具有指导和借鉴意义.With the further development of the an oilfield, the studies on the changed laws and mechanism of the reservoir property parameters become more and more important. 0il-water relative permeability curve is the integrated reflection of the filtration characteristics of the oil and water phases and one of the basic data of the reservoir numerical simulation. , so more and more attention has been focused on how to accurately understand and reasonably select and deal with the oil-water relative permeability curve. Accurate calculation of the relative permeability and mapping the curves can effectively determine the distributions of the oil, gas and water in the reservoirs, and ana- lyze the water producing rules of the oil wells by means of the relative permeability data. Great progresses on the studies of the methods and approaches have been made in foreign countries. The calculating methods can be classi- fied into the following three kinds ： analyzing method, semi-analyzing approach and history matching, each of them possesses its own merits and dismerits, all the achievements can guide and present the references for the later devel- opment of some mature long-period waterflooded oilfields in China.
