摘要: 由累积产水量(Wp)与累积产油量(Np),或水油比(WOR)与累积产油量(Np)在半对数坐标纸上构成的关系图,人们叫做水驱曲线。对于预测水驱油田的未来开发动态和最终采收率,这是一个很重要的方法。因此,在国内外得到了广泛的应用。在本文中,基于油水两相流动的驱替理论和方法,包括巴克莱·列弗雷特和韦尔杰分别提出的驱动前缘方程和平均含水饱和度方程,以及艾富罗斯提供的经验方程,本文导出了水驱曲线的不同关系式。其中包括童宪章命名的甲、乙和丙型水驱曲线。

Abstract: Plots constructed on semilog coordinate paper for cumulative water output (Wp)vs cumulative oil output (Np), or cumulative water-oil ratio (WOR)vs cumulative oil output (Np) are called water drive curves,a useful tool for making predictions of the performance and ultimate recovery factor of an oil field that has been widely adopted. Based on the displacement theory for two-phase flow,including the frontaldrive equation and the average water-saturation equation proposed respectively by Buckley-Leverett and Welge, also the empirical equation by Ilflos, several different relationship of water drive curves, including types A, B and C as defined by Tong Xianzhang, are derived.
