In this paper, a systematic approach which is able to consider different types of geological uncertainty is presented to model the waterflooding process. The proposed scheme, which is based on control and system theories, enables the experts to apply suitable techniques to optimize the production. By using the developed methodology, a reasonable mapping between defined system inputs and outputs in frequency domain and around a specific operating point is established. In addition, a nominal model for the process as well as a lumped representation for uncertainty effects are provided. Based on the proposed modeling mechanism, reservoir management goals can be pursued in the presence of uncertainty by utilization of complicated control and optimization strategies. The developed algorithm has been simulated on 10th SPE-model#2. Observed results have shown that the introduced methodology is able to effectively model the dynamics of waterflooding process, while taking into account the assumed induced geological uncertainty.

在本文中，提出了一种能够考虑不同类型的地质不确定性的系统方法来模拟注水过程。所提出的方案基于控制和系统理论，使专家能够应用合适的技术来优化生产。通过使用开发的方法，可以在频域中以及特定工作点附近在定义的系统输入和输出之间建立合理的映射。此外，还提供了该过程的标称模型以及不确定性影响的集总表示。基于所提出的建模机制，在存在不确定性的情况下，可以通过利用复杂的控制和优化策略来实现储层管理目标。所开发的算法已在第十个SPE-model＃2上进行了仿真。
