Abstract: Mary mathematic models have been applied to forecasting production rate and cumulation of oil and gas reservoir.It is difficult for oil engineers to use the models correctly because these formulae are miscellaneous,isolated each other,and have no any relationship among them.This paper presents a generalized model of forecasting production rate of oil and gas reservoirs.The model was deduced analytically and inductively based on life-limit system theory.By the way,the widely used twelve models in life-limit system theory can be obtained by selecting reasonable constant of the model.The simplified twelve models include famous economis increasing Gompertz model,Logistic Model widely used in society field,Arps hyperbolic decline model in petroleum engineering,Gamma Model and HCZ Model which covered the common branch of life-limit system theory.
