动态预测油气田产量的多层拟合方法

A multi-layer match method for prediction of production dynamic of oil or gas filed

分析了中心差分法建立的模型 ,提出了已有经典开发模型与中心差分法建立的CDM( 2 ,1)模型相结合的多层拟合预测油气田产量的方法 ,该方法能够比较准确地预测油气田产量的动态变化规律 ,消除了产量波动的影响 ,计算精度控制在

A Multi\|layer match method of combining classic development model with CDM(2,1) model established by method of cent difference is hold out based on analyzing vary models established by method of centered difference. This method can accurately predict dynamic variety law of production of oil or gas field, it can avoid effect of production wave, then, the error will be under 4%.
