复合驱工业试验区剩余油分布研究

Study on Remaining Oil Distribution of Composite Drive in Test Area

位于七东 1区克下组油藏中南部的复合驱工业试验区已处于特高含水、低产油开采阶段 ,开发形势相当严峻。该文在油藏描述的基础上 ,分析了油藏的油水运动规律 ,通过油藏动态法、岩心分析法、数值模拟法及水淹层测井解释 ,结合地质特征与生产测试资料 ,从不同侧面描述剩余油的分布状况和量值大小 ,为复合驱工业试验方案编制 ,为三次采油。

The test area of composite drive, which is located in the middle and south of Triassic Lower Karamay Formation in East District No 7-1 has at present entered into a stage of ultra-high water-cut and low yield, with the development situation deteriorating. Based on reservoir description, this paper analyzed migration of oil and water in the reservoir. The writers described distribution pattern of remaining oil in various aspects , applying reservoir performances, core analyses, numerical modeling and logging interpretation of watered-out formation, while combining with geological features and production test data.The article can contribute to preparing programs of composite drive test, tertiary oil recovery and EOR.
