摘　　要：马36井区经过多年开发现已进入高含水开发阶段,受开发年限长、注水见效特征复杂等影响,注入水推进方向及剩余油分布规律目前尚不明确。通过单井组生产动态分析,结合动态监测结果,认为马36井区注水见效方向4个,平面上剩余油主要存在于注入水主流线侧缘、注入水推进方向对侧,纵向上剩余油主要存在于储层中上部。该研究为下步剩余油挖潜指明了方向。The Ma36 well area has been under development for many years and has now entered a stage characterized by high water cut.Influenced by the prolonged duration of development and the intricate characteristics of the waterflood response,the directions of waterflooding advance and the distribution patterns of residual oil remain unclear.Through the production dynamics analysis of individual well groups and corroborated by dynamic monitoring data,it is determined that there are four discernible directions in which waterflood shows an effective response in the Ma36 well area.Spatially,the residual oil predominantly resides along the edges of the main streamlines of injected water and on the opposite side to the direction of waterflooding advance.Vertically,the residual oil is mainly present in the middle to upper sections of the reservoir.This research provides guidance for subsequent efforts to tap into the remaining oil reserves.
