摘要

东营断陷盆地已知油气藏的分布均受盆地区域性盖层控制。盆地内部是沙一段泥岩盖层

西部是馆陶组浅层泥岩盖层

南部是大面积分布的火成岩盖层。三种不同层位区域性盖层的有机配合

阻止油、气散失

使该盆地成为渤海湾油区众多含油气盆地中含油气最富的盆地

并控制了油气藏在盆地中的分布规律。

Abstract

The distribution of discovered oil and gas pools in Dongying fault-subsided Basin is controlled by regional caprocks. The caprocks are: mudstones of the first member of the Shahejie Formation in intra-part of the basin

the shallower buried mudstones of the Guantao Formation in the west part and wide spread igneous rocks in the south part. The organic coordination of caprocks in the three different horizons has successfully protected oil and gas from escaping

made the basin the richest one among all hydrocarbon-bearing basins within the Bohai Bay petroliferous province and controlled the distribution regularity of oil and Ras pools.
