摘要
为拓展济阳坳陷深层勘探新领域,本文以东营凹陷孔店组和沙四段沉积特征为研究对象,探讨了早始新世构造变动特点,指出始新世早期(孔店组—沙四段下亚段沉积时期)是区域应力环境发生大转折的时期,由此提出了"立交桥式"勘探思路。
The paper discussed the structural transition during early Eocene, by taking the features of the Ek and Es4^1 of Dongying sag as the researching objects, to expand the exploration area for deep formation in Jiyang depression. Pointed out that the early Eocene, during the sedimentary period of Ek and Es4^1, was the period which major aerial stress environment changes occurred major. Based on this view, an exploration thought of ＂over pass＂ was proposed.
