Abstract: The physical properties of Liaohe ageing oil and viscous crude oil were studied and making a basis of their treatment technology.The results show that the heavy oil of Liaohe is medium crude oil but ageing oil is heavy crude oil according to the method of density classify.The result of TBP distillation shows that the initial boiling of heavy oil and ageing is correspond.The gasoline fraction(<200℃)rate of heavy oil and ageing oil are 7.70% and 2.70%,the diesel oil fraction(200~350℃) rate are 19.81% and 10.45%,the wax fraction(350~425℃)are 12.27% and 10.19%,the residual oil fraction (above 425℃) are 6.82% and 13.94%.Heavy oil all fractions rate are higher than ageing oil.The total fraction of heavy oil is 46.60%(to 464℃),but ageing oil is 37.28%(to 500℃).

摘要： 对辽河油田稠油及老化油进行物性分析,为研究老化油和稠油的处理工艺技术打下基础。结果表明,按密度分类法可知,辽河油田稠油为中质原油,而老化油为重质原油。实沸点蒸馏结果表明,辽河油田稠油和老化油初馏点相当,稠油和老化油的汽油馏分(小于200℃)收率分别为7.70%,2.70%;柴油馏分(200~350 ℃)收率分别为19.81%,10.45%;蜡油馏分(350~425℃)收率分别为12.27%,10.19%;渣油馏分(大于425 ℃)收率分别为6.82%,13.94%。稠油各馏分收率高于老化油各馏分收率,稠油总收率为46.60%(到464℃)而老化油总收率为37.28%(到500℃)。
