石油是一种深藏在地底下的矿产物,主要是由许许多多不同的碳氢化合物所组成,这些碳氢化合物在化学上我们统称之为烃。各种不同的烃分子有大有小,构造也彼此互异。在普通温皮之下,它们可以成为固体,液体,气体三态而存在。石油就是这些东西的复杂的混合物。把石油从地下取出,直到分成各种各样的石油产品,就得经过探勘,钻井,采油和精炼等一系列的科学方法。甚至贮藏和运输,也得有相当的科学常识,才能减少浪费,消除事故。所以石油工业是一门包含丰富科学内容和复杂科学技术的工业。石油无论在国防建设上,工业建设上以及日常生活的需用
Petroleum is a mineral product that is buried deep under the ground. It is mainly composed of a large number of different hydrocarbons. We collectively call these hydrocarbons chemically hydrocarbons. Various different hydrocarbon molecules are large and small, and their structures are also different from each other. Under ordinary warm skin, they can exist as solids, liquids, gas tristates. Oil is a complex mixture of these things. The removal of oil from the ground until it is divided into various petroleum products requires a series of scientific methods such as exploration, drilling, oil extraction and refining. Even storage and transportation must have considerable scientific knowledge in order to reduce waste and eliminate accidents. So the oil industry is an industry that contains rich scientific content and complex science and technology. Petroleum needs in national defense construction, industrial construction, and daily life
