摘要
提出了采用动态驱替实验数据——岩芯末端的流体产量(或采收率)作为宏观拟合变量计算油水相对渗透率曲线的最优化方法(也称自动历史拟合方法),编制了相应的计算软件AMK2-1。并且,利用正常情况的实验数据对该软件进行了验证;然后,对用E.F.Johnson等人的方法求出的相对渗透率曲线异常的情况进行了实例计算,计算表明该软件的应用效果良好。
An optimistic method (called also automatic history matching method) for calculatingoil and water relative permeability curves from dynamic displacement experimental data——fluid production or recovery at the outlet end of the core is developed.The correspondingcalculating software AMK2-1 is worked out. Morever, the software is tested with thenormal experimental data. Then, the software is used for some cases in which the oil-waterrelative permeability curves are abnormal if JBN method is used.The results show that thesoftware is efficient.
