摘要
本文提出模型参数估计的多步广义梯度法和建模的多层曲线拟合方法，在油田注水系统建模项目中得到成功的应用，所建模型均有很高的精度。
In this paper, a multi-step generalized gradient method estimating model parameters and a multiple stage curve fitting method building models are put forward. They are successfully applied to modeling of an oil field flood pattern. These models are with very high precision.
