| 摘 要： | 通过对东营中央洼陷带沙三段浊积砂体的物源和成因类型分析认为该区在沙三段沉积时期形成了南部物源和东部物源共同起作用的沉积格局。其中，南部的物源影响了整个中央洼陷带，沙三段共形成5套规模较大的缓坡远岸浊积扇序列；而东部的物源只影响东营三角洲前缘的局部地区，形成了一些规模较小的滑塌浊积扇。同时指出梁家楼地区沙三段上亚段底部发育的缓坡远岸浊积扇属于较罕见的大型低位扇体系，并认为东营中央洼陷带沙三段下亚段也具有该类成因扇体的发育条件，其勘探潜力优于沙三段中、上亚段，发现大型的、以缓坡远岸浊积扇为储层的岩性油藏的可能性较大。

| Abstract: | Different views of the source area and origin1 types of turbidite sand-bodies in the Third Member of Shahejie Fm.(Es_3) in the central Dongying Depression have existed for many years. The authors think that the eastern and southern source area were contributing together in the sedimentary period of Es_3 after synthetically geological research in the great scope. The southern source area central depression belt and formed 5 sets of sequence of far-shore turbidite fan system on gentle slope.The eastern source area only affected partial region of Dongying delta and formed some small delta-slumping turbidite sandbodies.It was pointed out that the lower part of Es_3 has the probability for find large-scale lithological reservoir.Geological research realed that the sedimentary framework of the southern and eastern provenaces plays important role in the sedimentation of Es_3. |
