东濮凹陷文明寨深层地质特征解析

Geological Feature Analysis on Deep Layer of Wen Mingzhai Oilfield in Dongpu Depression

在断层认识、地层统层及储层砂体研究的基础上 ,对文明寨油田Es4及Mz深层的地层特征、构造特征、储层特征及油气藏特征等方面分析研究 ,研究认为Es4沉积环境以三角洲前缘为主 ,Mz以漫湖沉积为主 ,物源方向来自西部。根据复杂断块油气田特征 ,提出寻找勘探目标应以构造高部位 (垒块 )。

This paper studied the features of deep layer,structure,reservoir and oil/gas accumulation in Es 4and Mz of Wen Mingzhai oilfield based on fault understanding,universal stratigraphy,and reservoir sand body research.It is considered that the sedimentary environment in Es 4is dominantly delta front,and is flood sediment in Mz;material is sourced from the west.According to the characteristics of complicated fault-block oil field,structure high(horst) and the waist in faulted block area should be the main exploration targets.
