国外高含水砂岩油田提高水驱采收率技术进展

         

摘要

针对我国东部老油田水驱开发工作所面临的诸如地下认识体系需要重建、井网系统需要进一步完善等难点、热点问题,以国外47个高含水砂岩油田注水开发状况为资料来源,总结了国外高含水砂岩油田注水开发特征,详细分析了国外高含水砂岩油田二次开发的技术、措施,同时对国外高含水油田近年来在地质、油藏工程、工艺技术等方面研发应用的新理论、新技术进行了论述,对我国东部相似油田进一步提高水驱采收率具有一定的指导作用。%Abstract: Currently, the high water cut oilfield in eastern China have met many technical bottleneck problems that underground oil-water systems need to be rebuilt and well-patter need to be improved further. Based on the development data from 47 foreign high water cut sandstone oilfields, the waterflood development characteristics of foreign high water cut oilfields were summarized, and the redevelopment techniques and measures in high water cut stage of them were analyzed in detail. Furthermore, the new theories and technologies on geology, reservoir engineering and technology were also discussed. These measures adopted in foreign high water cut sandstone oilfields can provide certain guidance for improving waterflood recovery efficiency in similar oilfield of eastern China.
