摘　　要：黄骅坳陷埕海断裂缓坡区具有优越的成藏背景,是油气勘探的主要领域之一。通过系统解剖埕海断坡区构造、沉积、储层及油藏特征,明确了阶状断裂斜坡油气成藏主控因素及油气富集规律,提出充足的油气源、良好的储盖组合、基岩潜山背景下的断阶构造、长期继承性发育的断层是油气成藏的主要控制因素。宽缓斜坡始终是油气运移的主要指向区,断裂、不整合面及砂岩输导层三者不同的配置关系构成了研究区多种油气运聚方式,形成了大面积、多层系的油气聚集区。高斜坡和低断阶勘探程度低、潜力大,是下一步重点勘探目标区。The gentle slope area in Chenghai Fault Zone of Huanghua Depression was one of the main fields of oil and gas exploration because of its superior reservoir forming background.By analyzing the characteristics of the structure,sedimentary reservoirs and oil bearing areas,the main oil control factors and hydrocarbon accumulation regularity of the step fault zones were clarified.It is put forward that a sufficient oil source,good combination of reservoir and cap rocks,fault terrace structure and long-term inherited fault are the main controlling factors of oil and gas accumulation in the background of bedrock buried hill.The gentle slope is always the main region of oil and gas migration,different collocation relationships among faults,unconformity surfaces and sandstone transport beds constitute many oil and gas migration and accumulation modes in the study area.With the great potential in low exploration degree of high slope and low fault zone.It is the important target area for next exploration.
