Study on prediction model of fracturing result in Hujianshan Oilfield

According to the problems in Hujianshan Oilfield that the formations are complex and the hydraulic fracturing results are not ideal, based on the statistical analysis of historical data of hydraulic fracturing of 117 wells, making use of gray correlation analysis, the influence weights of all factors for treatment results are obtained; and applying the method of multivariate quadratic nonlinear regression equation, the prediction model of hydraulic fracturing results is established. By practical application of this model, it is concluded that the coincidence rate is 90.8% for sample points; the prediction coincidence rate is 84.8% for newly fractured wells. The result shows that this model has strong pertinence and precision, being able to provide guidance for hydraulic fracturing optimization .
