This paper discusses the method unifying various forecast models for oil and gas field output with variable dimension fractal model(in which the fractal dimension D may be taken as power series,trigonometric series and the like about,but is not a constant),the reason for this is that various forecast models may be transformed to the variable dimension fractal model.
