model prediction
1.The results from two cases of model prediction in water environment show better prediction effect and are compared with the project pursuit regressive (PPR) model.
8.By selecting different characteristic parameters of the gen er alized mathematic model for production prediction of oil-gas fields given in th e literature,12types of related models are obtained such as Weng cyclic model,log normal distribution model,Rayleigh prediction model,Beta cyclic mo del,Hubbert resource prediction model,HCZ model,Arps decline model,Kopatov d ecline model,etc.
