濮卫环洼带沙三段油藏特征分析

濮卫环洼带是东濮凹陷中央隆起带北部的一个次级负向构造单元。通过对濮卫环洼带沙三段构造特征、储层特征、盐岩分布规律及油气成藏规律的分析，指出在洼陷带东翼以顺向断块油藏为主，西翼以反向屋脊式断块油藏为主，构造-岩性复合型油气藏分布于洼陷的南部和北部。该研究成果用于勘探部署工作中，取得了较好的勘探效益。

The Analysis for the Characteristics of the Oil Pool in the Member Es3 Oil-bearing Belt around Pu-Wei Sag

The oil-bearing belt around Pu-Wei sag is a sub-ordinary negative structure unit in the northern part of Dongpu depression.Based on the analysis for the characteristics of the structure and reservoir,the distribution of the salt and the oil pool formation,this paper indicates that the consequent fault blocks are important in the eastern flank of the sag,where as in the western flank,the antithetic fault blocks.The structure-stratigraphic oil pools are mainly distributed in the northern and southern part of the sag.The result of the research has been applied to the exploration work and made effective benefit.
