摘　　要：为了完善水驱动态理论,建立了一个基于流管法的五点法井网的数学模型。通过对于单流管模型中驱替过程的叠加计算,求解了该流管模型,并可以计算出油藏的水驱动态参数。通过分析计算出的产油量、产水量和采出程度的动态变化,结合驱替前缘动态,发现流管中注入水的突破会影响动态结果。该研究结果为水驱开发及调整提供了理论指导。In order to improve the theory of waterflooding performance,a mathematical model of five-spot pattern is developed using stream tubes.By superposition calculation of displacement process in single tube model,the solution of the stream-tube model is obtained,and the waterflooding per-formance parameters of the reservoir can be calculated.With the analysis of the dynamic changes of calculated oil rate,water rate and oil recovery combined with the displacement front,it can be concluded that water breakthrough in the stream tube affects the changes of performance results.The results provide theoretical guidance for development and adjustment of waterflooding.
