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。Based on the analyses of Arps production decline law and changes of remaining reserve-production ratio. a simple and convenient method for estimating decline factors and recoverable reserves during decline period in any oil- field was presented. It is indicated that this can be able to meet the requirements of actual production. Using this method. such unreasonable cases as estimated recoverable reserves are less than accumrlative production or declie factors are bigger than 1, hence causing estimation of the reasonable reserves to be invalid or insignificant,could be voidable.Fur- thermore,the classification of production decline types and range of decline factor values have been approached in this paper.
