一种油田产量的拟合并应用于预报的方法

A Method of Fitness and Its Application in the Prediction of Oil-Field Output

本文首先介绍了油田产量数据的预处理方法;在油田产量数据预处理基础上提出了一种参数化的Weibull模型,这种模型对于预处理的产量数据具有很好的拟合性态,利用这种拟合可以简单地给出油田产量原始数据的一种非时变预报,这种方法较之时变参数预报法既简便又可达到同样的预报精度。

A method for preprocessing the data of oil field output is described in this paper. On the basis of preprocessing the oil output data, a parametric model-Weibull model is presented. This model has good fitness for the preprocessed output data. By using such fitness, non-time varying prediction of the original oil field output can be easily given. Compared with the time-varying parametric predition method, this one is easier and practicle. Examples are given to show the reliability of this method.
