12种预测油气田产量模型之间的关系

针对 文献1]提出的油气田产量预测广义数学模型,通过对待定参数取不同的特征值,可以得到Weng旋回模型、对数正态分布模型、瑞利Rayleigh)预测模型、贝塔旋回模型、预测资源量的Hubbert模型、HCZ模型、Arps递减模型和Kopatov递减模型等目前已出现的多种产量预测模型;Weng旋回等产量预测模型是文献1]中的产量预测广义数学模型的特例。因此,文献1]中的广义数学模型通式”的推出,使各类预测模型与广义预测模型之间有机联系起来,使产量预测模型研究提升到了更高的层次,必将产生积极的指导意义。

The Relationship among 12 Generalized Models for Production Prediction of Oil-Gas Fields

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.,among which Weng cyclic model and others for production pre diction are the special cases of generalized mathematic model in the literature .Therefore,the general formula for generalized mathematic model can be u sed to establish relations between other models for production prediction and ge neralized mathematic mod-els,hence helping upgrade to a higher level for study of the production predictions,which is of positive significance for field use .
