摘　　要：夏509断块位于惠民凹陷临南洼陷江家店鼻状构造中部,断块内部构造复杂。本文通过文献查阅、岩心观察和测井资料分析,确定研究区为扇三角洲沉积环境。在此基础上,分析该区是由惠民凹陷南部的鲁西隆起中生界地层的风化剥蚀产物提供初始物源,并不断向北西方向推进,形成扇三角洲前缘亚相沉积为主的沉积体系。Xia 509 fault-block lies in the middle of Jiangjiadian nose-like structure in Huimin sag,it has many faults and very complex structure.Through refering literature、observing core and analysing log data,this paper thinks this area is fan-delta sedimentary envionrment.Based on this,this paper identifies this area is supplied with original source by sedentary product of Luxi uplift in south of huimin sag,the source is pushed to the northwest,shaping fan-delta sedimentary system.
