孔南地区沧东凹陷预探目标潜力分析

沧东凹陷位于黄骅坳陷的南端,是孔南地区的主要生油凹陷,钻探揭示 O、Mz、Ek3、Ek2、Ek1、Es3、Es2、Es1、Ng 共 9 套含油层系,发现了枣园、王官屯两个亿吨级大油田,是发现油藏类型多、油气储量多、剩余资源潜力大的凹陷之一,其勘探前景广阔。本文重点开展沧东凹陷孔店组、沙河街组沉积、储层研究,以地层岩性油气藏研究为核心,充分利用新技术、新方法,落实沧东浅凹陷勘探潜力,为孔南地区准备后备预探领域。

The exploration prospect of Cangdong sag

Cangdong sag is located in the south of Huanghua Depression.It is one of the main oil kitchen sags in the southern of Kongdian. Nine oil-bearing series is drilled including of O、Mz、Ek3、Ek2、Ek1、Es3、Es2、Es1 and Ng. Zaoyuan and Wangguantun oil field with reserve of nearly 108 tons have been discovered. Many types of reservoir and oil&gas reserve have been found in Cangdong Sag, which has amount of remaining hydrocarbon resource. This paper discusses the sedimentary and reservoir characteristics of Kongdian and Shahejie Formation. With the new technology and methodology, the prospect of Cangdong Sag is debated on and the pre-prospecting targets are put forward.
