预测水驱油田含水率的Usher模型

Usher Model for Water Cut Prediction in Waterflood Field

预测水驱开发油田含水率随开发时间的变化规律具有重要意义。基于水驱油田含水上升规律,将广泛用于经济和资源预测的Usher模型用于含水率的预测。通过对Usher模型的分析,指出目前用于含水率预测的Logisitic模型和Gompertz模型为Usher模型的两种特殊形式,并结合矿场应用实例证明了该模型的实用性和有效性。

It is significant for predicting watercut vs time in a waterflood field.Usher model,a model for general prediction of petroleum economy and resources,is used to predict watercut based on the increasing watercut in waterfood field.By analysis,this paper points out that available Logistic model and Gompertz model are the specific ones of Usher model.And field application indicates the practicality and validity of Usher model.
