Abstract: By selecting different characteristic parameters of the general ized mathematic model for production prediction of oil-gas fields given inthe literalture [l], 12 types of related models are obtained such as W eng cyclic model, log normal distribution model, Rayleigh prediction model, Betacyclic model, Hubbert resource prediction model, HCZ model, Arps decline model, Kopatov decline model, etc., among which W eng cyclic model .and others for production prediction are the special cases of generalized mathematic model in the literature [1]. Therefore, the general formula forgeneralized mathematic model can be used to establish relations between other models for production prediction and generalized mathematic tipgngeleteadgilavelforltlye therpreodegfefieigligiureicdifofigieiyiveignience fotfefedeuse.
