摘要：

对于已经进入产量递减阶段开发的油气田，产量递减法是预测油气田可采储量、剩余可采储量、产量和递减率的重要方法。基于广义的Arps指数递减、双曲递减和调和递减，结合陈氏线性递减模型，建立了广义递减模型。该模型可以用于油气田可采储量、剩余可采储量、产量和递减率的预测。递减因子m是判断和区分递减类型的重要参数。当m=2时为线性递减；当m=1时为指数递减；当0 <m <1时为双曲递减；当m=0时为调和递减。通过对五里湾1区、东河塘和法哈牛3个已开发油田的实际应用表明，所建立的广义递减模型实用有效。

Abstract:

For developed oil and gas fields that have entered the production decline stage, production decline method is an important method to predict recoverable reserves, remaining recoverable reserves, production and decline rate of oil and gas fields. Based on the generalized Arps exponential decline, hyperbolic decline and harmonic decline and combined with the linear decline proposed by Chen, a generalized decline model was established. The model can be used in the prediction of recoverable reserves, remaining recoverable reserves, production and decline rate of oil and gas fields. The decrease factor m is an important parameter to judge and distinguish decline types. When m=2, it represents a linear decline; when m=1, it represents an exponential decline; when 0 < m < 1, it represents a hyperbolic decline; when m=0, it represents a harmonic decline. The practical application in three developed oil fields such as Wuliwan area 1, Donghetang and Fahaniu indicates that the established generalized model is practical and effective.

Key words: oil and gas field, generalized decline model, recoverable reserves, remaining recoverable reserves, production, decline rate, prediction
