裂谷盆地的含油性,已为近十多年来我国和国外石油勘探和科学研究的实践所证实。 欧洲北海油区,就是六十年代后期开始勘探,七十年代发展起来的大油区。北海为一较大的裂谷系。从北海北部延伸到尼德兰,可能直至莱茵裂谷系,长度超过1600公里。在北海盆地中,挪威自1969年发现了埃科菲斯克大油田和弗里格大气田以后,至1974年仅五年时间,就发现油气田20个,石油可采储量7亿吨,天然气可采储量5500亿立方米。 The oiliness of the rift basin has been confirmed by the practice of petroleum exploration and scientific research in our country and abroad in the past decade or so. The European North Sea oil zone is the large oil zone that began exploration in the late 1960s and developed in the 1970s. The North Sea is a larger rift system. Extending north of the North Sea to Netherland, it may reach the Rhine rift system for more than 1,600 kilometers. In the North Sea Basin, Norway discovered the Ekofisker and Friggas gas fields in 1969. Only five years after 1974, 20 oil and gas fields were discovered, with recoverable reserves of 700 million tons and natural gas recoverable Reserves 550 billion cubic meters.
