摘要： 通过对Ａｒｐｓ产量递减规律与油田剩余储采比变化规律关系的分析,给出了一种计算递减期油田递减指数与可 采储量的简便方法。实践表明,该方法计算精度能够满足生产需要,使用该方法,可以避免求出的可采储量低于累积产 量以及递减指数大于1而求不出可采储量的不合理现象。文中还对递减类型的分类及递减指数取值范围进行了讨论。

Abstract: Based 011 lthte allalyses of Arps production deeline law and changes of remainling resorve-productiot ralio. a simple and convenient letod for estimating de:line factors and recovcrable reservcs during lecline period in d11V oilfield was presented. It is indicatedl thal this ('an be dble lo meet the requirements of actual production. Using this methud. such unreasonable cuses as estinated recoverable reserves are less thal acuinulative producliol or decline factors are bigger than 1, henve causing estimation of the reasonable reservcs lo be invalid ur iusignificanl. ("ould be voidable. Furthermore. the classification of production decline lypes arnd lange of deline faclor values have been approached in this paper.
