Abstract: Water displacement characteristic curve is a useful tool in reservoir engineering.It can be used to predict recoverable reserves,recovery efficiency and future reservoir performance in a water drive oilfield.Therefore,it has been widely used in practice.Based on the Buckley-Leverett,one-dimensional displacement theory of oil-water two phase flow,a new relationship between the cumulative produced liquid and the cumulative produced oil is provided in this paper.The application of this expression with actual data indicates that the relationship is applicable and effective.

摘要： 水驱曲线在油藏工程中是一个很有用的工具.它可以用于预测水驱油田的可采储量、采收率和未来的开发动态.因此,在实践中得到了广泛的采用.本文基于Buckley-Leverett的油水两相流动的一维驱替理论,提供了累积产液量和累积产油量之间的一个新型水驱曲线关系式.实际资料的应用表明,该法是有效的.
