对青海原油进行了综合评价。结果表明,该原油密度小（849.9 kg/m3）,硫含量0.51%,蜡含量4.98%,属于轻质含硫含蜡原油。重整原料和汽油馏分烷烃含量较高,适宜做乙烯裂解料,煤、柴油馏分变色严重,硫、氮含量高,均需加强加氢精制效果。减压蜡油Cp高（70.63%）,CA低（18.01%）,残炭值低（0.0256%）,重金属含量较小,既适合生产高黏度指数润滑油,又是催化裂解的优良原料。渣油的硫含量较高（6 200 mg/kg）,沥青质含量高（6.2%）,重金属铁（45.73μg/g）、镍（35.29μg/g）、钙（73.86μg/g）含量较高,作催化裂化原料时,应注意其掺炼。

The overall evaluation of Qinghai crude oil indicates that the crude oil is lightweight with low density of 849.9kg/m3,sulfur for 0.51% and wax for 4.98%.The reforming materials and gasoline distillation cut are good cracking materials owing to their high alkane content.Kerosene and diesel distillation cut need intensified hydrogenated refining because of serious discolourment as well as high contents of sulfur and nitrogen.The decompressed wax oil is suited for manufacture of high viscosity index lubricant and it is also fine material for catalytic cracking for high Cp（70.63%）,low CA（18.01%）,low carbon residue（0.025 6%） and less heavy metals.Residual oil needs to be especially noted for proportionment when used as catalytic cracking material,owing to high content of sulfur（6200 mg/kg）,asphalt（6.2%）,heavy metals like iron（45.73 μg/g）,nickel（35.29 μg/g） and calcium（73.86 μg/g）.
