摘要
王场油田北断块经过多年注水开发,受储层物性差异,水驱状况的影响,不同区域剩余油分布规律不同,西北部剩余油主要集中在油层内顶底部位,东南部油层物性差异大,动用差,剩余油连片分布,通过有针对性的调整可提高其动用程度,提高采收率。
After years of water flooding extraction, there are different distribution patterns of remaining oil in different areas of the north fault block of Wangchang Oil Field due to diverse reservoir physical properties and different effects of water drives. For example, remaining oil in the northwestern area mainly concen- trates at the top or the bottom of the reservoir, while in the southeastern area, remaining oil concentrates in pieces due to different physical properties of oil reservoirs and difficulties of extraction. This paper suggest targeted adjustments to make it easier to tap into these areas and thus improving oil recovery.
