摘　　要：双河油田现已进入特高含水阶段，采出程度高，产量递减快，缺乏资源接替。而经证实含水在40％～80％之间的中淹层尚未进行系统挖潜，为弥补产量递减，挖掘中淹层潜力，提出了中淹层的综合识别方法，设计出现场可操作的中淹层挖潜流程。双河油田中淹层资源状况分析研究表明其剩余可采储量占总剩余可采储量的29．4％，且有一定厚度，物性中等。经25口井中淹层补孔单采结果表明，平均单井日增油5．1t。降水17．3m3。证实中淹层可作为今后挖潜主要对象。This paper presents the comprehensive identification methods of moderate watered-out zones and the flowsheets designed for tapping the production potential.Based on analysis, the residual recoverable reserves in the moderate watered -out zones in Shuanghe oilfield make up 29.4% of the total residual recoverable reserves of the oilfield. After reperforating at the moderate watered-out zones in 25 wells,single zone produation showed that the average incremental oil per day per well was 5.1t and the water production rate droped 17.3m3 .It proved that the moderate watered- out zones would be the targets to develop the remaining oil.
