东濮凹陷是渤海湾盆地的一部分。在渤海湾盆地其它坳陷中，上第三系是一个重要的含油气层系，但东濮凹陷至今尚未发现油气田。本文采用对比的方法，分析了上第三系勘探现状、石油地质条件和成藏机理。在讨论其利弊的基础上，指出明化镇组（Nm）应是它的主要勘探目的层，中央隆起带北部地质条件最佳，是最现实的地区，兰聊等主要断层附近及西部斜坡带具备形成地层、岩性、构造多种类型油气藏的条件。
Dongpu Depression is part of the Bohai Bay Basin. Among the other Depression in the Bohai Bay Basin, the Upper Tertiary is an important petroleum-bearing gas system, but so far no oil and gas fields have been found in Dongpu Depression. In this paper, the comparative method is used to analyze the status quo of exploration in Upper Tertiary, petroleum geological conditions and mechanism of hydrocarbon accumulation. On the basis of discussing the advantages and disadvantages, it is pointed out that the Minghuazhen Formation (Nm) should be its main exploration target. The northern part of the central uplift has the best geological conditions and is the most realistic one. Near the major faults such as Lanchat and the western slope With the formation of strata, lithology, structural conditions of many types of reservoirs.
