泡沫驱经验模型及其应用

气体以泡沫的形式注入油藏是一种极有效的提高采收率方法。泡沫可作为流度控制剂，也可作为封堵剂或被用来控制生产气油比。到目前为止，已有许多泡沫驱模型用来模拟泡沫驱的动态，如机理的、经验的和平经验泡沫模型。介绍了两种最常用的泡沫驱模型；ＰＢＭ模型和经验模型。其中，经验模型由于需要的实验数据量少，只需增加一个额外的表面活性剂流动方程等，所以被广泛采用。为此，开发了一个简易的泡沫驱经验模型。

A NEW EMPIRICAL MODEL AND ITS APPLICATIONS FOR FOAM FLOODING

Foam Flooding is an effective process in enhanced oil recovery for the favorable mobility control ability. In the past several decades many efforts were made to find models, including theoretical, empirical and semi-empirical prediction models, for predicting reservoir performance during foam flooding. A new empirical model was developed in this paper by adding a flow equation for surfactant element. The new model was proved to be more effective because of the less empirical data required, lower calculation cost and simpler and faster screening process.
