摘要
以位于厄瓜多尔奥联特盆地东翼斜坡带上的DORINE-FANNY油田M1油藏为例,从边底水波及情况、井网完善程度以及局部隔夹层的遮挡3个方面对强天然水驱厚层砂岩油藏高含水期剩余油分布规律进行了研究,并从边底水未波及区、井网未完善区以及局部隔夹层遮挡区3类剩余油富集区的动用阐述了厚层砂岩油藏高含水期剩余油挖潜的措施和效果。
By taking M1 reservoir of Dorine-Fanny Oilfield located in the eastern limb slope of Orient Basin in Ecuador for example,the distribution law of remaining oil was studied at the high water-cut stage from the aspects of edge and bottom water wave,well-pattern completion and local interbed barrier .From the aspects of oil producing oil enriched area in non-sweep area of edge water,non-perfect area of well patterns and local interbed barrier area,the measures and effect of tapping the potential in sandstone reservoirs at the high water-cut stage.
