摘要
系统分析了饶－霸凹陷文安斜坡议论堡构造下第三系油气藏形成的主要控制因素：①ＮＷ向鼻状构造控制油藏分布；②稳定的盖层控制主力含油层系的分布；③沙二段圈闭类型控制其油气富集程度；④油源条件是控制沙一上段油藏形成的关键。上述研究成果不仅使本区勘探取得了重大突破。
The forming conditions for lower Tertiary reservoir of Yilunpu structure of Wenan slope, Baxian sag,are analyzed comprehensively in this paper, the main control factors for reservoir forming in this region are summarized as follows: the distributions characteristics of reservoir, main oil bearing strata, are respectively controlled by NW fault nose, stable cap rock trap type of member two, Shahejie formation,controls the oil and gas enrichment degree. Oil source condition is the criticized factor of reservoir formation of the upper member one, Shahejie formation.Great breakthrough has been made in the exploration of this area based on those above. It will be of great significance for the understanding and research of reservoir forming conditions and enrichment characteristics at the slope of dustpan like single fault sag in Jizhong depression, which is also meaningful for the exploration direction.
