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，而且对冀中多数箕状单断凹陷斜坡成藏条件和富集规律的认识与研究以及勘探方向有重要的指导意义
The main controlling factors for the formation of Tertiary reservoirs under the Wen-Bao slope in Rao-Ba Sag are analyzed systematically: ①NW nose-shaped structure controls the distribution of reservoirs; ②the stable cap rocks control the distribution of the main oil-bearing strata; The trap type controls the degree of oil and gas accumulation. (4) The oil source conditions are the key to controlling the formation of the upper part of the sand. The above research results have not only made a major breakthrough in exploration in this area, but also have important guiding significance for the understanding and research of reservoir forming conditions and enrichment rules for the majority of the half-graben single-break sag in central Hebei
