Based on beta function of distribution density in probability statistics and derived densityfunction by tranformation,a beta cyclical model was developed and a method extracted for the model pa-rameters was presented. By using this model, predictions of production and recoverable reserves in Ninghaioilfield were made. The results showed that the model is suitable for prediction of some other field's pro-ductions and recoverable reserver.
