至1973年底,世界上剩余石油可采储量为840亿吨,同年总产量为27.85亿吨。产量达1亿吨以上或近1亿吨的有美国、苏联、沙特阿拉伯、伊朗、委内瑞拉、科威特、利比亚、尼日利亚、加拿大及伊拉克等10个国家。油气富集区基本上遍及各大洲。大洋洲虽然目前石油生产能力较低,但澳大利亚近年来发展也较快,1973年产量达2,070万吨,剩余石油可采储量为4.19亿吨,随着勘探程度的加强,还将有可能增加新的储量。石油高 By the end of 1973, the world’s remaining oil recoverable reserves amounted to 84.0 billion tons. In the same year, the total output was 2.785 billion tons. There are 10 countries such as the United States, the Soviet Union, Saudi Arabia, Iran, Venezuela, Kuwait, Libya, Nigeria, Canada and Iraq that produce over 100 million tons or nearly 100 million tons. Oil and gas-rich areas are basically all continents. Oceania Although oil production capacity is low at present, Australia has also developed rapidly in recent years. In 1973, it produced 20.7 million tons of oil and the remaining oil recoverable amount was 419 million tons. With the enhancement of exploration, it will also be possible to add new Reserve. High oil
