Abstract: By choosing the possible influence factors for injection profile from geology and production, the analysis of correlation between the factors and the injection profile is made respectively. The result shows that the correlation between them is not purely ensured by functions. Prediction of the injection profile can not be conducted just by one of the factors but using non-linear method with multifactors such as permeability capacity, permeability contrast, oil-water well connected condition, sand type, connected oil wells, connecting well spacing and stimulation measures. The case study shows that this method is effective in practice.

Key words: water injection profile, geologic factor, production factor
