摘　　要：世界上已发现的油气储量99%以上都赋存于含油气盆地中的沉积岩或喷出的火山岩内,分布在变质岩潜山内的油气储量不超过1%,且一般位于距潜山顶部150m以内,距潜山顶面超过500m的油气藏尚未见报道。中国石油辽河油气公司2005年在渤海湾盆地辽河断陷沉积岩之下0~1600m的片麻岩及混合角闪岩内发现了储量超过3000万吨的大油田。这一发现表明,地质条件类同的辽河断陷中央隆起带变质岩潜山内的油气勘探前景广阔;渤海湾盆地变质岩潜山内幕油气资源潜力有待重新评价和认识;地球上能够开展油气勘探的领域比我们曾经想象的大得多。99% of the hydrocarbon resources have been discovered within the sedimentary rocks or erupted volcanic rocks of hydrocarbon bearing basins in the world,only less than 1% of hydrocarbon resources distributed within metamorphosed rocks of buried hill,and the buried depth is no more than 150m generally.The depth of hydrocarbon accumulated in metamorphosed rocks is over 500m from the surface of buried hill has not yet been reported until now.In 2005,Liaohe Petroleum Co.,Ltd.of CNPC discovered a large oilfield in the gneiss and mixed amphibolite buried 0~1600m below sedimentary rock of Liaohe Fault-depression of Bohai Bay basin,the hydrocarbon reserve is more than 30 million ton,which indicates a good hydrocarbon exploration prospect in the similar metamorphosed rocks of buried hill with the central uplift belt of Liaohe Fault-depression.The hydrocarbon resources potential in metamorphosed rocks of buried hill in Bohai Bay basin is need to be re-evaluated and understood,the hydrocarbon exploration area is much greater than we have ever imagined in the world.
