一种预测水驱油田含水率的新模型

在水驱油田开发中,预测含水率随开发时间的变化规律具有重要的意义.基于水驱油田含水率上升规律,将一种预测油气田累积产量的模型用于含水率的预测,从而建立了一种新的预测水驱油田含水率的模型,且该模型可以简化为Logistic模型.运用二元回归法求解该模型.用胜利胜坨油田和河南双河油田的实际含水率数据对该模型进行了验证,通过对...

A new model of predicting water cut of the water flooding oilfield

It is significant for predicting the changing law of water cut with different development time in water flooding field.A model for predicting cumulative production was used for predicting the water cut based on the increasing law of water cut of water flood field,then a new model of predicting water cut for water flood oilfield was developed,and the model could be simplified into Logistic model.The model can be solved by the binary regression method,which was verified by using the actual water cut data of Shengtuo oilfield in Shengli and Shuanghe oilfield in Henan.By compa-ring with the predicting results of Logistic model and Gompertz model,it shows that the model is more accurate.So it can be use to predict the water cut of oilfield and guide the development of water flood oilfield.
