摘要
东濮凹陷沙一段、东营组油气藏分布受古近纪构造格局控制,而新近系油气藏主要与新生的近东西向断层有关;浅层油气主要有2期注入,分别对应东营组、明化镇组沉积末的构造运动期,多数油气藏形成于东营组沉积末期,局部油气藏在明化镇组沉积末期仍有烃类充注,部分油气藏在此时发生了调整、破坏。
Esl, Ed reservoir distribution of Dongpu Depression is controlled by the Paleogene tectonic framework, and Neogene reservoir is mainly related to newborn nearly east-west trending faults l There are mainly two injection of shallow oil and gas ,which respectively correspond to the tectonic movement of the end of Ed and Nrn Formation. Most reservoir formed in the end of Ed deposition, and the local reservoir still has hydrocarbon injection in the end of Nrn deposition,and adjustments and destruction of some reser- voir take place at that time.
