摘　　要：北珀斯盆地是澳大利亚西海岸主要含油气盆地之一,盆地的构造演化时间上,具有“幕式”特征;空间上,具有自东向西的迁移规律。受构造影响,盆地圈闭主要是断块和断鼻。圈闭的形成,破坏及重组受控于裂陷活动。另一方面,各期裂陷造成主力烃源岩时代上自东向西由老变新,且自东向西趋向成熟。The North Perth Basin is one of the major hydrocarbon-bearing basins on the west coast of Australia. The tectonic evolution of the basin has the characteristics of episode. Correspondingly, in space, basin rifting has the same migration law from east to west. On the one hand, the basin traps are mainly fault blocks and fault noses, and their formation is controlled by rifting activities in different episode, destroyed and reorganized in the later episode. On the other hand, the age of the main source rocks has changed from old to new from east to west in various stages of rifting activities, and tends to be mature from east to west.
