摘要
牛屠油田东营组马圈子油层为牛居油田主要油层。该油层沉积相环境为一套河湖交互相.陆上辫状河沉积砂体可划分为河道底部沉积单无和河道充填砂坝沉积单元;水下辫状河道粒度变细,河道砂坝发育较差,并向曲流河道转变.除水下河道砂体外,还发育与河道伴生的砂坝和砂席.这些砂体形成了重要的层状构造油藏.
ajuanzi reservoir is the main productive formation in Niuju Oil Field. Its depositional environment is fluviallacustrine factes. The onshore braided fluvial sedimentary system consists of sedimentary element at the stream channel basel and streem channel filled sedimentory element of sand bar. The subaqueous braided channel deposits changed into finer grains and the stream channel sand bar was poorly developed and changed into winding stream channel. Besides subaqueous channel sand bodies,sand bars and sand sheets coexisted with channel deposits. These sand bodies formed the main layered reservoir.
