全球发育的含油气盆地有上千个，根据盆地结构特征可将含油气盆地分为3 大类型：克拉通盆地、断陷盆地和前陆盆地。笔者按这3 大类型盆地论述其油气分布规律。克拉通盆地：油汽主要分布在盆地内的古隆起、古斜坡，区域性的不整合及断裂带内；断陷盆地：油气主要分布在深凹带内的构造带、陡坡带和缓坡带；前陆盆地：油气主要分布在前陆断摺带、斜坡带、逆埯带及坳陷帶。这些规律性的认识，对全球油气勘探工作具有重要的指导意义。

According to the structural characteristics of petroliferous basin can be divided into three major basins：Craton basins，Rift basins and Foreland basins，thousands of which developed in the global. The distribution of oil-gas is discussed in the three major basins. Oil and gas is mainly distributed in the paleo uplift，paleo slope，regional unconformity，fault belt of the Craton basins，and is also distributed in the structural belt，steep slope belt，gentle slope belt of the Rift basins and in the fault-folded belts，slope belt，overthrust belt，depression belt of the Foreland basins，which proved that it has important guiding significance in the oil-gas exploration.
