由于石油具有热值高、使用方便、便于贮存和运输以及燃烧后没有灰分等一系列优点,所以被广泛地应用于工业、交通运输、农业机械化以及国防建设等各方面。随着生产建设的发展,各国对石油的需求量日益增加,而全世界可开采的石油储藏量却日益减少,石油的祜竭已成为人们越来越担心的事情。自1973年以来,世界性的石油供应日益紧张,价格一再暴涨。这就是所谓石油危机或称能源危机。
Because petroleum has many advantages such as high calorific value, easy to use, easy storage and transportation and no ash after combustion, it is widely used in industry, transportation, agricultural mechanization and national defense construction. With the development of production and construction, the demand for petroleum in various countries is on the increase. However, the amount of oil reserves that can be mined in the world is decreasing day by day. The depletion of oil has become an increasingly worrying issue. Since 1973, the global oil supply has become increasingly tense, and prices have skyrocketed. This is the so-called oil crisis or energy crisis.
