由于原油的组成非常复杂,建立一个科学的分类标准是很困难的。到目前为止,国内外还没有一个国际通用的原油分类标准。 我国石油工业发展较晚,60年代原油的产地还较少,还没有意识到要对原油进行分类。70年代初,国内输油部门曾有人称大庆原油为“三高(高含蜡量、高凝点、高粘度)”原油。这在当时还是可以的,因为没有更多的原油可资比较。近20年来,我国石油工业发展迅速,从陆上到海上,新油田
Due to the complexity of crude oil composition, it is difficult to establish a scientific taxonomy. So far, there is no internationally accepted crude oil classification standard at home and abroad. The development of China’s oil industry is relatively late, the origin of crude oil in the 1960s is still relatively small, have not yet realized that the classification of crude oil. In the early 1970s, Daqing crude oil was once known as “three highs (high wax content, high freezing point and high viscosity)” crude oil in the domestic oil transportation department. This was still possible at the time because no more crude could be compared. In the past 20 years, the petroleum industry in our country has developed rapidly from land to sea and new oilfields
