Analysis and Application of Gray Correlation Method |

| Abstract: | Taking a block of No.2 Oil Production Site in Daqing oilfield as test site,in this paper,major factors which influence fracturing effects can be analyzed through gray correlation method.Utilizing mean transformation and range transformation methods,oil increment of sixteen wells of sample data can be respectively forecasted.Prediction models can be established by multiple regression method,and the results show that predicted values of range transformation methods are more accurate.Absolute average error of predicting wells is 0.52 t/d and the value meets the implement requirements of fracturing technique in field. |
