摘　　要：为了研究影响辽河油田SEC动态储量关键因素,运用单因素评价分析、多因素约束的方法,分析了各因素对SEC动态储量敏感性的影响。研究表明:原油价格是最敏感因素,低油价时期,常规油田经济极限产量增大而PD储量减少,操作成本是最关键因素;评估单元、递减曲线类型、评估初始点、递减率是SEC动态储量评估合理性的重要因素。该研究成果对其他油田公司评估SEC动态储量具有一定的指导意义。In order to study the key influence factors for the SEC dynamic reserve in Liaohe Oilfield, univariate analysis and multivariate constraint were used to investigate the sensitivity of SEC dynamic reserve. Result indicates that the crude oil price is the most sensitive factor. The economic limit production increases and the PD reserve decreases for conventional oilfields in low crude oil price condition. The second is operating cost. The assessment unit, production decline curve type, initial assessment point and production decline rate are considered as the key influence factors for the SEC dynamic reserve. This research could provide certain guidance for the SEC dynamic reserve assessment in other oilfields.
