摘要
在水驱油田动态分析、产能预测以及规划方案编制中,含水率与时间变化规律是最常用的预测方法之一。基于描述物理和化学反应的非线性Logistic模型,建立了水驱开发油田含水率随开发时间变化的预测模型。最后,通过该模型与常用的线性Logistic、Gompertz和Usher等模型进行对比,提出的新模型预测精度更高。
In the process of dynamic analysis,production forecasts and planning of waterflood oilfield,the change rule of the water content with time is one of the most commonly used methods.In the light of the Logistic model of the physical and chemical reactions description,the model of predicting water content change with development time was established for water-flood oilfield.Finally,compared with the commonly used linear Logistic model,Gompertz model,Usher model and other models,the new model has higher prediction accuracy.
