摘　　要：东濮凹陷胡-庆断阶带属构造型斜坡带,发育不同级次的断层,断层对油气分布和聚集起着十分重要的控制作用,断块构造是基本的油气聚集单元,不同的构造部位油气运聚特征不同。通过对该区断裂构造特征分析,探讨了三个台阶及断层夹缝带等不同构造部位的油气分布,其中二台阶油气最为富集;一台阶及断层夹缝带只有局部油气聚集;三台阶油气资源最差。同时提出了下步滚动勘探的有利方向。Hu-Qing fault step zone in Dongpu depression is a structural slope band and develops different level faults,which play an important role for controlling the oil-gas distribution and accumulation.The fault block structure is the based oilgas accumulation unit and different structural zones have the different migration and accumulation.The oil-gas distribution of the different structural zones is discussed by the analyses of the fault structural features,which shows that the second step zone is the main abundance zone,that the first step zone and the fault belt accumulates oil-gas only in the local traps and that the third step zone is the sparest zone.At the same time,favorable rolling exploration zones are pointed in this paper.
