| 摘 要： | 针对孤东油田七区西Ng5^2＋3单元储量动用程度高、水淹严重和剩余油分布复杂等问题，对其曲流河沉积主体点坝砂体内部构型进行了研究。研究结果表明，曲流河活动河道满岸宽度约为300m，单一曲流带宽度约为2400m，点坝长度约为1430m，点坝砂体内部侧积层斜列式分布，单一侧积体宽度约为200m，侧积层倾角为3°-5°，侧积层间距为50～130m；点坝砂体内的剩余油分布主要受侧积层的位置与注采井射孔井段组合关系的影响。

| Abstract: | In view of questions of high degree of producing reserves,serious waterflooding and complex distribution of remaining oil of unit Ng5~(2+3)in the west 7th block,Gudong Oilfield,internal architec- ture of point bar,the host sediment of meandering river,is re- searched.The width of active channel of the meandering river is about 300m,the width of single meandering belt is about 2 400m,and the length of the point bar is about 1430m.The lateral accretion shale bedding inclines to abandoned channel, the width of... |
