| 摘 要： | 北凹是南黄海盆地北部坳陷最具勘探潜力的凹陷之一,是一个＂北断南超＂的典型箕状断陷湖盆,其中古近系阜宁组为一套厚度近2 000 m的河湖相砂泥岩地层,可分为4段。综合应用测井、岩芯、地震剖面等资料,分析北凹阜宁组沉积体系及沉积相,共识别出2种主要沉积体系：湖泊和扇三角洲沉积体系,基本继承了北部物源为主的沉积格局。凹陷中部为滨浅湖相沉积,是典型的陆相断陷湖盆的沉积发育模式。

| Abstract: | The northern sag was one of the most important potential oil and gas exploration areas in the north depression of South Yellow Sea Basin,and was a typical dustpan shaped subsidence lacustrine basin with a fault as its north boundary and a slope to the south. Funing Formation in the northern sag was 2 000 m thick and mainly comprised fluvial-lacustrine sandstone and mudstone,and Funing Formation is divided into 4 members. Based on data of log,core and seismic profile,the sedimentary system and sedimentary facies of Funing Formation in northern sag were analyzed. There were two kinds of sedimentary systems,including fan delta and lacustrine system,fan delta in the north fault is the main provenance inheritance,shallow lacustrine system was the largest area in the depression. |
