摘要
基于油水两相的驱替理论和实验研究成果,即巴克莱·利弗雷特(Buckley-Leverett)的水驱油非活塞式理论,韦尔杰(Welge)的平均含水饱和度方程以及艾富罗斯(Эфрос)的实验理论研究成果,推导出经典水驱油理论所对应的含水率与采出程度关系曲线、水驱特征曲线以及含水率上升曲线。该方法推导过程中虽未引入油水两相相渗函数,但亦能导出累计产油量与累计产液量的关系式,与以往水驱曲线推导方法有很大差异。经油田实际应用证明,该方法效果很好,值得推广应用。
Based on Buckley-Leverett theory of water displacing oil in non-piston, Welge＇s average water saturation equation and Efros＇ experimental results, the water cut vs recovery efficiency curve, the water drive characteristic curve and the water cut rising curve corresponding to the classical water displacing oil theories are derived in this paper. Although the oil-water two-phase relative permeability function is not introduced in the process of derivation, the cumulative oil production vs cumulative liquid production can also be given from the theoretical and experimental research results, which has a big difference with previous derivation methods for water drive type curves. Through field application, the effect is very good and worthy of popularization and application.
