摘　　要：对乌兰管道首站北疆原油进行了综合评价。结果表明,该原油密度大(867.3 kg/m3),硫含量低(0.1%),蜡含量高(11.46%),属于中质低硫高蜡原油。重整原料和汽油馏分烷烃含量较高,适宜做乙烯裂解料。煤油馏分硫含量高,柴油馏分氮含量高,均需加强精制效果。减压蜡油酸值高、黏度指数低,不适合生产高黏度指数润滑油,Cp较高(56.34%),CA低(7.69%),残炭值低(0.013%),重金属含量较小,是催化裂解的优良原料。渣油较轻,属于第二类渣油,硫含量较小(0.26%),沥青质含量较低(1.5%),是理想的催化裂化原料的掺料或焦化原料。Overall evaluation of crude oil in North Xinjiang on Urumchi-Lanzhou Pipeline shows that the crude oil is of high density（867.3 kg/m3） with low sulfur and high wax,which is 0.1% and 11.46% respectively,so it is a middle quality crude oil.The reforming materials and gasoline distillation fractions are good cracking materials owing to their high alkane content,while kerosene and diesel distillation fractions need to be intensified refined because of their high sulfur and nitrogen contents,The decompressed wax oil is unsuitable for manufacture high viscosity index lubricant because the oleic acid content is high while the viscosity index is low.However,with high Cp（56.34%）,low CA（7.69%）,low carbon residue（0.013%） and less heavy metals,it is fine material for catalytic cracking.Residual oil is an ideal catalytic cracking and coking material,owing to small proportion of sulfur（0.26%） and asphalt（1.5%） belong to the second category in residual oil.
