摘　　要：里107断块边水活跃,依靠天然能量开发,此类油藏初期产量高,但含水上升快。近年来通过多种监测手段明确了边水的驱动特点,摸清了平面、层间及层内剩余油分布规律。通过运用打调整井、调堵、分层采油等有针对性的挖潜手段,油藏开发效果得到进一步提升,增加可采地质储量117.2×10~4t,使最终采收率提高了23个百分点,对同类油藏剩余油挖潜和提高采收率有一定的借鉴意义。Edge water at Li107 fault block is active,and such reservoirs have high initial production relying on the natural energy to develop,but whose water cut rises fast. In recent years,through a variety of monitoring methods,the drive characteristic of edge water has been clear about,and the plane,interlayer and the regularity of distribution of remaining oil in the layer are found out. By targeted potential means of drilling adjustment Wells,plugging,and layering oil production,oil reservoir development effect has been further promoted,increasing recoverable reserves of 117. 2 x 10~4 t,the ultimate recovery increased by 23%,which has certain reference significance for extracting potential to remaining oil of the similar reservoir and improving recovery.
