近几年世界能源消耗总量达80亿吨石油当量,其中石油天然气占60%以上。预测未来相当长的时期内,油气能源的重要作用是其他能源难以替代的。石油是一种非再生能源,地球上的储量总是有限的。综合目前公布的数字,世界已探明可采石油储量在1200～2000亿吨,可再开采约60～90年。各国能源专家普遍认为,到2050年左右,以石油为主要能源的时代将要过去。随着对油气的不断需求,从世界石油勘探的发展
In recent years, the world’s total energy consumption reached 8 billion tons of oil equivalent, of which oil and natural gas accounted for more than 60%. In the foreseeable future, the important role of oil and gas energy is that it is hard to replace other energy sources. Oil is a non-renewable energy source and reserves on Earth are always limited. According to the figures published so far, the world has proven recoverable oil reserves of 120 to 200 billion tons and can be re-mining for about 60 to 90 years. Energy experts generally believe that by 2050, the era of oil as the main energy source will pass. With the constant demand for oil and gas, the development of oil exploration from the world
