摘　　要：在总结前人的潜山分类基础上,从形成潜山的地质背景和成因出发,把冀中坳陷潜山分为地貌潜山和构造潜山两大类,进一步又可分为6小类。冀中坳陷古潜山是在特定的构造背景下形成的,空间上可组合成饶阳式和霸县式两种模式。不同类型的潜山具有不同的分布规律和成藏条件,发育单断式、断阶式、斜坡式和侵蚀型4种类型的潜山油气藏,其中单断式最发育,断阶式和斜坡式次之,侵蚀型少见。On the basis of buried hill classification methods and geological background of buried hill formation and causes,buried hills could be divided into landform buried hill and tectonic buried hill in Jizhong Depression, and could be further divided into 10 subtypes. Buried hill in Jizhong Depression was formed in special structural background and was combined into Raoyang-style and Baxian-style in space. Different types of buried hills have different distribution laws and reservoir conditions. Four kinds of buried hill reservoirs, such as single-cut type, step-fault-type, slope- type and erosion- type are developed,in which single-cut type is the most developed buried hill reservoir, step-fault type and slope-style is in the second place, erosional form is the poorest.
