Summary:Abstract With the development of oil field, it enters the period of super high water cut and measuring well selection is becoming more and more difficult. In order to forecast well productivity more scientific and reasonable after fracturing, this paper presents a method of predicting production after fracturing (factor analysis-formula deduction-instance validation). Its basic idea is that, firstly analysing all factors affecting fracturing productivity, and then using the orthogonal design method to quantify the main factors according to the influence weight, again fitting production forecasting out formulas after fracturing according to the score situation by a statistical principle, finally production forecasting formulas for instance analysis to verify its rationality. The results of the research results show that the prediction method can basically accurately predict the productivity after fracturing and can effectively meet the needs of oilfield development, and provide a reliable theoretical basis for well selection and formation selection in fracturing plan.
