| 摘 要： | 以东营凹陷孔店组和沙四段沉积建造和构造特征为研究对象，依托高精度三维地震反射资料，通过地震反射界面确认、沉积层厚度和构造形迹精细解剖、探讨了东营凹陷在早始新世构造变形的特点，指出孔店组晚期——沙四下段沉积期是区域应力环境发生大转折期，由此提出了油气勘探的“立交桥”式思路，勘探意义重大.

| Abstract: | Taking sedimentary formation and structural features of Ek and Es4 in Dongying sag as an object of study,using high precision 3D data,the paper discussed the structural transition during early Eocene by identification seismic reflection interface,detailed architecture analyses sedimentary layer and structural trace.Pointed out that the early Eocene,during the sedimentary period of Ek and Es14,was the period which major aerial stress environment changes occurred.Based on this view,an exploration thought of "over pass" was proposed and its petroleum prospecting significance is great. |

| Keywords: | Jiyang depression structural transition Ek over pass hydrocarbon accumulation |
