实沸点蒸馏数据是评价原油的一项重要内容。但当油样量不足无法做实沸点蒸馏，或不需要分析馏分油性质，而急需了解某原油馏分分布时，就需采取用油量少、速度快的模拟蒸馏方法。大庆油田设计院从美国HP公司引进一套HP5880／5890A气相色谱仪及蒸馏软件，根据成品油及原油蒸馏的有关资料进行测试，从而获得原油模拟蒸馏数据。
Boiling point distillation data is an important part of the evaluation of crude oil. But when the oil sample is not enough to do real boiling point distillation, or do not need to analyze the nature of distillate oil, and the urgent need to understand the distribution of a crude oil fraction, you need to take less oil, high speed analog distillation method. Daqing Oilfield Design Institute introduced a HP5880 / 5890A gas chromatograph and distillation software from HP Company of the United States to test the crude oil distillation data according to the related data of the refined oil and crude oil distillation.
