摘要:
基于油井产量递减的统计研究和理论分析,Arps提出了著名的指数递减、双曲线递减和调和递减,尤其是指数递减因简单、实用和可靠得到了广泛应用。然而,Arps的3种递减只适用于油气田投产即进入递减的无峰开发模式产量和累积产量的预测。在Arps的指数递减的基础上,笔者提出了广义指数递减模型,在此基础上进行了进一步推导,得到了更为简单实用的预测方法,适用于无峰、单峰、均峰和多峰等开发模式,可用于产量、总累积产量、可采储量、剩余可采储量、采出程度和储采比等多个参数的预测。实例应用表明,本文提出的广义指数递减模型实用有效。
Abstract:
Based on statistical research and theoretical analysis of oil well production decline, Arps presented the famous exponential decline, hyperbolic decline and harmonic decline. Among them, the exponential decline is widely used because it is simple, pragmatic, and reliable. However, the three decline types Arps presented are only applicable to forecast production rate and cumulative production rate of no-peak development mode which goes into stage of decline directly after production. Based on the exponential decline of Arps, the author proposed a generalized exponential decline model, and further derived and obtained a simpler and more practical prediction method, which is suitable for development models such as no-peak, single-peak, average-peak, and multi-peak. The generalized exponential decline can be used to predict parameters, such as production rate, total cumulative production rate, recoverable reserves, remaining recoverable reserves, recovery degree and reserves production ratio etc. The application case indicates that the generalized exponential decline is practical and effective.
