摘　　要：综合分析国内外储气库建造标准与注气驱油藏开发基本条件,提出提高采收率的储注气油藏筛选标准及其指标;运用基于可拓学的物元理论,建立了储注气油藏多级物元模型;引入可拓集合中的关联函数,根据综合关联度大小对某油田4个油藏进行三级可拓评价。实例表明,该方法对某油田多个储注气油藏筛选评价具有较好的适应性,可以避免过去传统方法的评价失效与偏差。By comprehensively analyzing construction standards of gas storages and basic development conditions of gas injec- tion oil reservoirs at home and abroad, this paper presents selection criteria and their indexes of oil reservoirs that can both meet the requirements of gas storage and enhanced oil recovery（EOR）through gas injection. On the basis of establishing indexes, an extensi- ble method is proposed. Based on matter-element theory, a multilevel matter-element model for gas storage and injection is estab- lished, By introduction of a group of extensible correlation functions, 4 oil reservoirs in a certain oilfield are evaluated for three-level extension with the comprehensive correlation value. It has been proved that this method is well adapted to carry out extension evalu- ation several oil reservoirs in an oilfield for gas storage and EOR through gas injection. The appraisal results show that it can avoid the failures and errors of conventional evaluation methods.
