近年来,世界上含蜡原油的开采量大大增加。含蜡原油凝固点高,管线输送比較困难。由于輸送高凝固点原油管綫的設計、建設和操作都是新問題,所以有关1955年底交付使用的奥捷克-苏阿特—格罗兹内輸油管线的数据有着一定的参考价值。原油的一般性質見表1。在管綫設計編制之前,格罗茲內科学研究所會从事原油 In recent years, the world’s extraction of waxy crude oil has greatly increased. Waxy crude oil has a high freezing point and pipeline transportation is more difficult. As the design, construction and operation of crude oil pipelines carrying high freezing points are new issues, the data on the Austrian-Surte-Grozny pipeline to be delivered for use by the end of 1955 is of some value. The general nature of crude oil in Table 1. Before the pipeline design was prepared, the Grozny Institute of Science conducts crude oil
