摘　　要：为解决广义Arps递减理论在直线递减期累计产量和技术可采储量公式精度有限的问题,经严格的数学推导建立了评价单元直线递减期累计产量预测和可采储量评价新模型。新模型应用初始稳定日产量和初始日递减率、极限递减生产时间或初始月递减率及初始年递减率等较易获取的参数来计算初始产量和可采储量,具有易于操作,简便实用的特点;并在靖安油田五里湾开发区应用,与老模型相比效果明显。新模型不仅是对Arps递减理论的完善和补充,也具有很好的实用性和较高的理论价值。In order to solve the problem that the accuracy of the formula of cumulative production and the problem of limited precision of technical recoverable reserves formula in the period of linear decline of generalized Arps decline theory,a new prediction model of cumulative production and a new model of recoverable reserves evaluation of evaluation unit in linear decline period are established by strict mathematical derivation.The new models are easy to operate,simple and practical.With new models,the initial production and recoverable reserves can be calculated by using the parameters easily obtained,such as initial stable daily production,initial daily decline rate,limiting decline production time,initial rate and initial decline rate.Compared with old models,the effect of new models is obvious in Wuliwan Development Zone of Jing'an oilfield.The application indicates that new models are not only the complement to Arps decline theory,but also have good practicability and high theoretical value.
