摘　　要：断块是重要的油气储集单元,断块群则是断块的有序组合,是油气藏组合体。断块油气藏的勘探迫切需要一个合理的断块群分类方案。文中从几何学—运动学方面出发,讨论了裂陷盆地断块群分类方案,然后结合裂陷盆地结构,讨论了不同构造部位可能出现的断块群类型,也从这个角度初步讨论了断块群的成因。最后,结合东濮凹陷实际,讨论了不同构造部位发育的不同类型断块群的构造特点和含油气性。Fault blocks are important oil-bearing units. A fault block group, the reservoir assemblage, consists of associated fault blocks. At present, a reasonable category for fault block groups is essential to the exploration of fault block reservoir. In terms of geometry and kinematics, a kind of category is tentatively put forward. The relationship between the kinds of fault block groups and the tectonic locations in rift basin is addressed as well. These relationships reflect the formation mechanisms of different fault block groups to a certain extent. Dongpu depression is taken as an example to demonstrate the tectonic characteristics and potential for exploration of the different kinds of fault block groups occurring in various tectonic locations.
