A method for predicting water-cut rate of water-drive oilfield

On the base of Model Gompertz of the economic increase and oil and gas resources increase prediction,the model of predicting water-cut rate in response to the variation of de- velopment time is established for water-flood oil field.The application in Daqing oilfield and Shengli oilfield indicate that the model can predict water-cut rate in the overall progress with simple calculation and relatively accurate precision of prediction.
