在全世界范围内,侏罗系—白垩系地层中的油气资源十分丰富,其分布具有十分鲜明的特征。具有侏罗—白垩系的含油气盆地构成了一个全球性地带。该带由西西伯利亚和阿姆河含油气盆地以及由此向南的波斯湾含油气盆地组成,从另一方向上,西加拿大含油气盆地以及一些临接落基山脉的含油气盆地也属于这一地带。西非、亚马逊河三角洲、马拉开波和墨西哥湾含油气盆地为这一地带的南半部。 Around the world, the oil and gas resources in the Jurassic-Cretaceous strata are very rich, and their distribution has very distinct characteristics. Petroliferous basins with Jurassic-Cretaceous formations constitute a global zone. The belt consists of the West Siberia and Amu and the Persian Gulf petroliferous basin to the south. On the other hand, the western Canada petroliferous basin and some oil-bearing basins next to the Rocky Mountains also belong to this zone. West Africa, the Amazon Delta, the Maracaibo and Gulf of Mexico oil-bearing basins are the southern half of the strip.
