义和庄凸起北坡是一个典型的多含油层系、多油藏类型的复式油气聚集带。受多期构造运动、沉积间断等因素影响,义和庄凸起北坡形成了复杂多样的圈闭及油藏类型。本文在储层、油源、圈闭等成藏条件分析的基础上,系统总结了义和庄凸起北坡的油藏类型、控制因素及分布规律,并根据目前的勘探现状,指出潜山、地层超覆、地层不整合等隐蔽性油藏是主要勘探方向,可为油气勘探提供科学依据。

The northern slope of the Yihezhuang Arch is a typical multiple oil and gas accumulation zone consisted of multiple oil-bearing series and multiple reservoirs types. Due to influence of tectonic movements, sedimentary break and other factors, traps and reservoirs were complicated and diversified. Based on the study of pool-forming factors such as reservoir, oil-source, trap and so on, the types, control factors and distribution of hydrocarbon accumulations in the northern slope of the Yihezhuang Arch were summarized. It was suggested that the subtle reservoirs such as those formed in buried-hill, unconformity and stratigraphic overlap were major targets for future exploration in the area.
