| Abstract: | For prolonged waterflood development in Pucheng Oilfield,water drive recovery factor of Oilfield is affected.Through profile control testing in many years,PI decision technique is summarized.Based on application of PI decision technique in 21 wells in the upper ES2 2 3 West Area of Pucheng Oilfield,the results show the stimulation effect is obvious.The paper presents theoretical basis,application and operational method of PI decision technique.Meanwhile,the application effect of PI decision technique in profile control well is evaluated. |
