摘　　要：对西藏伦坡拉原油做了综合评价 ,分析了原油和各个馏分的性质 ,结果表明 :该原油密度大 ( ρ2 0 =0 .94 92g/cm3) ,粘度高 (υ50 =2 3 4 55.5mPa·s) ,凝点高 ( 48℃ ) ,残炭较高 ,热值较高 ,蜡含量高 ,属高蜡原油。西藏伦坡拉原油实沸点蒸馏及窄馏分性质分析表明 ,原油初馏点为 1 34℃ ,小于 2 0 0℃汽油馏分收率为 1 .4 0 % ,柴油 ( 2 0 0～ 350℃ )馏分收率为 6.90 % ,润滑油 ( 350～ 50 0℃ )馏分收率为 1 7.0 6% ,大于 350℃重油收率高达 91 .4 1 %。该原油胶质含量高达 4 1 .4 3% ,沥青质含量低仅为 0 .4 7% ,硫含量低 ,属低硫中间基原油。The crude oil of Xizang Lunpala Oilfield was evaluated comprehensively. The properties of various distillates from this crude oil were analyzed and evaluated respectively. The results indicated that this crude oil has the characteristics of high density(ρ 20 =0.949 2 g.cm -3 ),high viscidity (υ 50 =23 455.5 mPa·s) , high solidifying point(48.0 ℃),high thermal energy and high wax content. Its initial boiling point is 134 ℃. The yield of gasoline fraction (boiling range low than 200 ℃) is 1.40%.The yield of diesel fraction(200～350 ℃) is 6.90%. The yield of lubricating oil (350～500 ℃) is 17.06%.The yield of heavy oil (boiling range more than 350 ℃) is 91.41%.This crude oil has low sulfur content, high resin content and low asphaltene content , which belongs to low sulfur intermediate base crude oil.
