一种新的油田产量递减阶段预测模型

油田产量递减规律研究是进行产量递减预测的一项重要任务。目前,Arps递减曲线是一种非常重要而又常用的预测油田产量递减规律的方法,此外,国内提出了很多预测方法,使产量递减预测方法更齐全、使用范围更广泛、预测精度更高。基于Arps递减规律推导过程得到一种新的产量递减模型,可简化为Arps指数递减形式,经实例计算,可以用来预测油田产量,以此指导油田开发和管理。

A NEW MODEL FOR OIL PRODUCTION DECLINE PREDICTION

Research of oilfield output degression law is an important job in production decline prediction.At present, Arps decline curve is a tranditional and important method for prediction of production decline law.There are some other predicting methods available in China which make the prediction methods more complete,accurate and popularized. A new production decline model based on Arps can be simplified as Arps exponential decline form.Case study indicates that it can be used to predict oil production and guide oilfield development and management.
