摘要： 当油藏的非均质性严重时,实测岩心相渗透率参数不具有代表性,在这种情况下,由波及系数修正法确定的水驱油藏理论含水率曲线与实际情况会有较大误差。提出用动态数据获得的相渗透率参数代替实测岩心相渗透率参数,改进了波及系数修正法。结果表明,用改进的波及系数修正法获得的水驱理论含水率能更准确地反映水驱油藏的含水上升规律。

Abstract: The relative permeability curves obtained by core testing is not representative in case of serious heterogeneity of reservoir, which tends to big error in the theoretic water cut curves of oil reservoir obtained by sweep efficiency modification method. This paper presents an improved method for substituting relative permeability curve obtained by core testing, in which the relative permeability parameter is given by dynamic data. The results show that the theoretic water cut curves obtained by this improved method is more proper to reflect the actual performance.

Key words: water cut, recovery, sweep efficiency, relative permeability curve, reservoir performance
