我国新疆的沙漠地带有一个叫克拉玛依的大油田,这是众所周知的。当今世界上第一大油田是地处沙特阿拉伯境内鲁卜哈里沙漠中的加瓦尔油田,它的储量高达122.5亿吨,大约是全世界已知石油总储量的1/9。世界上第二大油田是地处科威特境内的内夫得沙漠中的布尔干油田,它的储量达121亿吨,也占了全世界已知石油总储量的1/9左右。此外,中东地区乃至世界各地的沙漠里还分布着大大小小的很多油田。为什么大油田多分布在沙漠里呢?为揭开这个谜,科学家们作了不少研究,他们提出了多种观点。目前能让大多数人接受的观点是海洋石油成因学说。
It is well-known that there is a large oil field called Karamay in the desert area of our country. The world’s largest oil field is the Ghawar oil field located in the Ruphali Desert in Saudi Arabia. Its reserves are as high as 12.25 billion tons, about one-ninth of the world’s known total oil reserves. The second largest oil field in the world is the Balkan oil field in the Neffr Desert located in Kuwait with a reserve of 12.1 billion tons, accounting for about 1/9 of the world’s known total oil reserves. In addition, many large and small oil fields are also distributed in the desert in the Middle East and around the world. Why are the large oil fields distributed in the desert? To unravel the mystery, scientists made a lot of research, they put forward a variety of perspectives. The point that most people now accept is the theory of the origin of offshore oil.
