摘要:

通过对前梨园环洼下第三系沙三段层序界面的分析、对层序地层划分和体系域的研究;建立了前梨园洼陷的几种层序地层模式;进行了沉积相分析和砂体展布规律研究;分析了其岩性油气藏分布规律,对前梨园环洼地区岩性油气藏勘探提出了新思路。

关键词: 前梨园环洼, 层序地层模式, 岩性油气藏

Abstract:

Based on analyzing the sequence interface, studying sequence stratigraphy division and system realm of Sand 3 of Paleogene, Qianliyuan annular sub-depression, several sequence stratigraphic patterns were constructed in this paper. It also made study on sedimentary facies, the distribution law of sand body and lithologic reservoir, thus presented new thoughts for lithologic reservoir exploration in Qianliyuan annular sub-depression.

Key words: Qianliyuan annular sub-depression, sequence stratigraphic pattern, lithologic reservoirs
