A New Method to Predict Polymer Flood Performance

Through using frontal advance theory and empirical regression comprehensively, a model of forecasting the production of polymer and rule of change water cut. When this method is used, the pressure is changing, suppose a given liquid producing capacity that is “constant production to calculate pressure”. The established method is used to match and predict the change rule of the water cut and oil production in the twenty polymer flooding blocks. The result shows that the average relative error of oil production per month, water cut and accumulative oil production is less than 12%, 3% and 5% respectively. The accurary of this method is very high and can meet the demand of fleld application.
