摘要
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。基于物理学中的简谐振动原理,提出了把阻尼振动方程中的临界阻尼振动方程变形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。
Arps decline curve is a well-known reservoir engineering method for prediction of production decline low of oilfield. Also, there are many other predicting methods available in China, which allow such methods to be more perfect in technique, more widespread in applied field, and higher precision in prediction. Based on theory of simple harmonic oscillation in physics, this paper presents a novel model for production decline prediction given by deformation of critical damping oscillation equation which is predigested to Arps exponential decline form. The case study indicates that this model can be used for field production decline prediction as a guide for oilfield development and management.
