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
