摘要
按储层沉积旋回和沉积韵律特征，将三间房组油藏进一步细分为２４个小层。结果表明：油层动用程度好的层段主要为每一砂岩组底部的第３，４小层；明显的沉积旋回和韵律性加剧了注水开发中的层间、层内矛盾，使注入水单层突进严重，含水上升较快，开发效果不佳。
The Sanjianfang Formation′s oil reservoir can be divided into 24 substratums in detail on sedimentary cycle and sedimentary rhythmic character of reservoir.Affected by that, the well exploited sections are mainly the 3 rd ,4 th sand substratums that lie in the middle and bottom of every sandstone formation, the apparent sedimentary cycle and sedimentary rhythm augment the conflicts of interior reservoirs and exterior reservoirs.During the process of waterflooding, the injected water break through seriously in single layer,and the content of water increases quickly.The development result isn′t satisfying.
