摘　　要：油藏开发进入高含水期后 ,原油产量的递减是不可避免的。此时 ,对单井、井组或油田开发单元进行产量递减分析 ;不仅要分析理论递减率 ,还要分析直接反映开发单元动态变化的自然递减和综合递减。影响递减的主要因素是采油速度。Oil production decline is unavoidable after the development of oil reservoir entered high water cut period. At this time the oil production decline should be analyzed for single well, well group or development block of the oilfield. Not only theoretical decline rate, but also natural decline and composite decline that directly reflect the performance changes of the development blocks should be analyzed. The main influence factor of production decline is oil recovery rate. The linear relationship between them can determine the rationality of production decline.

关 键 词：油藏开发 高含水期 自然递减 综合递减 采油速度 合理性
