摘要(Abstract)：

根据岩心、地震、测/录井资料,在济阳坳陷车镇凹陷车15井区的沙三下砂砾体中识别出滑塌浊积扇和深水浊积扇.其中,车57井以粒度偏细且有根的深水浊积扇与深湖相互层为特色,车古25井以具水道补给的(有根的)滑塌浊积扇为特色.平面上,自北而南顺水道方向由陆向湖盆中心,依次分布着近岸水下扇、深水浊积扇或滑塌浊积扇、深湖亚相,两类扇体沿主构造线串珠状排列,包裹于大片的深湖相中,呈现"深湖包扇"的沉积格局.不同时期两类扇的演化不同:无根的滑塌浊积扇在第1期最为发育;第5期发生了湖平面上升,扇体范围明显缩小;第7期仅见有根的深水浊积扇与滑塌浊积扇,分布面积不大,但无根的滑塌浊积扇消失.

关键词(KeyWords)： 浊秋扇;沉积特征;分布格局;深水浊积扇;滑塌浊积扇;济阳坳陷
