稠油资源是非常宝贵的地下资源,其资源量十分丰富。据有关资料统计,目前世界上已探明的重油资源主要集中在委内瑞拉、前苏联、美国及加拿大等国。委内瑞拉东北部的奥立诺柯重油带核实地质储量达3000亿吨以上。美国重油资源的一半分布在加里福尼亚,地质储量近400亿吨,其余的一半分布于中部大陆。加拿大的重油资源主要分布在阿尔伯达省的阿萨巴斯卡、冷湖、维巴斯卡和匹斯河等四个主要沉积矿藏中,地质储量近1500亿吨。前苏联的重油资源主要分布于西西伯利亚盆地的巴塞诺夫约200余亿吨,包括中国在内的其它国家也有着极其丰富的稠油资源。这些重油资源的总地质储量总计达6 Heavy oil resources are very valuable underground resources, their resources are very rich. According to statistics, the world’s proven heavy oil resources are mainly concentrated in Venezuela, the former Soviet Union, the United States and Canada and other countries. The Orinoco Heavy Oilfield in northeastern Venezuela verified geological reserves of more than 300 billion tons. Half of the U.S. heavy oil resources are distributed in California with nearly 40 billion tons of geological reserves and the remaining half are distributed in the Central China. Canada’s heavy oil resources are mainly distributed in the four major deposits of Athabasca, Cold Lake, Verbaska and the Pythons in Alberta with nearly 150 billion tons of geological reserves. The former Soviet Union’s heavy oil resources are mainly distributed in the West Siberia Basin Basunov about 200 billion tons, other countries, including China, also has a very rich heavy oil resources. The total geological reserves of these heavy oil resources amount to 6
