大面积堵水调剖技术工业化应用研究

Industrial application in large-scale multiple water plugging and profiling technology

非均质严重的注水砂岩油藏在特高含水开发后期如何应用堵水调剖技术进一步提高油藏采收率 ,一直是国内外研究攻关的重大课题。基于精细油藏描述研究成果 ,优选合适的堵水调剖剂 ,配套完善注入工艺和评价技术是大面积堵水调剖工业化应用取得成功的关键。此技术已成为胜坨油田特高含水期开发提高水驱采收率的一项主导工艺 ,经济效益显著。图 2表 2参

In the research of anisotropy sandstone reservoir developed by water injection, how to enhance oil recovery of the ultra high water cut oilfields is an project for internationally reservoir engineering. The study introduces the application of multiple water plugging and profiling technology, with a large scale example from the Shengtuo Oil Field, which can be used in the ultra high water cut oilfields (entering a critical stage now). The authors analytically sum up the support technology of the industrial application in the large scale water plugging and profiling. The result of this study may be applicable to other reservoir similar conditions.
