Based on core and well logging data, the distal turbidite fan of Block Zhuang74 in Wuhaozhuang Oilfield can be divided into three subfacies, that is, root fan, middle fan and fan edge.

应用岩心、测井等资料将山东五号桩油田桩74块远岸浊积扇划分为扇根、扇中、扇缘3个亚相,其中扇中亚相划分为辫状水道、水道间、水道侧缘、扇中前缘及叶状体5个微相类型;阐明了研究区特低渗透油藏内储层的层内、层间及平面非均质特征;系统总结了微构造的类型及组合模式。

The southern source area central depression belt and formed 5 sets of sequence of far-shore turbidite fan system on gentle slope.

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。
