说起中国石油储藏最多的地方，很多人第一反应是新疆或者大庆那些陆上油田，但其实真正储量最大的得数南海这片海域。 南海油气资源丰富得让人咋舌，据权威数据估算，石油储量能达到上百亿吨级别，甚至比一些中东国家还多。 南海整个海域面积有350万平方公里，底下沉积盆地多达37个，是中国最大的海洋油气储存区。专家们通过地质勘探推算，海底油气田超过250个，石油部分 就占了世界总储量的好大一块。 比中东那些国家，南海的优势在于资源类型多样，不光石油，还有天然气4万亿立方米，可燃冰资源量折合194亿吨油当量。 南海的油气形成得益于地质构造复杂，欧亚板块和太平洋板块碰撞，形成了适合油气聚集的盆地，尤其是曾母盆地，那里储量超130亿吨，占了大头。 不过话说回来，南海油气开发不是那么简单的事。从历史看，上世纪70年代中东石油危机爆发后，各国开始重视海洋资源，中国也从那时起逐步涉足南海勘 探。 比方说，伊拉克的探明石油储量大约是260亿吨左右，科威特是140亿吨，而南海的石油资源预估在292亿吨以上，这还不算天然气和可燃冰那些额外资源。 全球石油总储量的四分之一可能就藏在这里头，让人觉得这地方简直是第二个波斯湾。波斯湾在中东那边是石油 ...
