双极预测模型在油田开发中的应用

Application of Bi-polar Prediction Model in Oilfield Development

水驱特征曲线、Gompertz预测模型在预测水驱油田开发指标中都有它们的局限性。为此 ,提出了一种适用范围更广的新的预测模型—双极预测模型。该模型可以对水驱开发油田含水率、油田的采收率以及可采储量等指标进行预测。该模型仅涉及到低渗透油田含水率与采出程度一组数据 ,同样可以推广到其它性质的油田 ,它在不同程度上反映了油田的开发效果。通过油田的实际运用表明 。

Water flooding characteristic plot and Gompertz prediction model have their limits in predicting the water flooding indexes. So this paper proposes a new one-bipolar prediction model,which can be used to predict the water cut,recovery and recoverable reserves of a waterflooded oilfield. This model only uses a set of data of the watercut and recoverable percent of reserves of low permeable oilfields,but it can also be used in other types of oilfields. The application shows the effect of the model.
