摘要
利用交联聚合物驱油是一种有效的提高采收率方式,为达到经济有效的驱油效果,合理设计注入参数尤为重要。以投入产出比最小为目标函数,建立了确定交联聚合物驱各段塞最佳注入参数的最优化数学模型,并将其转换为一个带有非线性约束的非线性规划问题,利用Matlab优化工具箱的fmincon优化模块对其进行了求解,并利用数值模拟方法对所求得的最优解进行了验证。
Oil displacement with crosslinked polymer was an effective way of enhancing oil recovery. It was critical important of designing rational parameters for economic oil displacement. By minimizing input/output ratio, an optimized mathematic model was determined for the optimal parameters of crosslinked polymer flood slug injection. It is transformed into programming problem with nonlinear restraint, and the problem is solved by using Fmincon optimization module from Matlab optimization tool box, and the result is verified by using numerical simulation method.
