摘　　要：介绍了对长庆原油进行的综合评价。结果表明:长庆原油属于优质的轻质低硫含蜡原油,馏分分布状况好。在生产装置炼制时,常、减压负荷均衡,易于平衡操作。初馏点～180℃馏分可做大乙烯裂解原料,但更适合做重整原料;145～240℃喷汽燃料组分收率较高,铜片腐蚀、硫醇硫不合格,说明长庆原油喷汽燃料中活性硫化物较多,在精制时应注意;柴油馏分柴油指数高、十六烷值大,腐蚀、酸度均符合成品柴油的标准。减压蜡油酸值小、粘度指数高,是生产润滑油基础油的理想原料,同时其Cp高、残炭值低,重金属含量不高,也是理想的催化裂解原料;>520℃的渣油沥青质含量较高,是生产沥青的理想原料,如果作为催化裂化原料,必须考虑调配比例,以防催化剂中毒。A comprehensive evaluation on the Changqing crude oils was made. The results showed that Changqing crude oil belongs to the light waxy oil with low sulfur and good distillate distribution. During refining, it is balance loaded under normal and vacuum pressure, and therefore is easily operated. IBP - 180℃ fraction can be used as ethylene cracking feedstock, and also can be used as reforming feedstock; 145 - 240℃ steam jet fuel component was obtained with high yield, but its copper corrosion and mercaptan sul- fur experiments are unqualified, this indicates that the active sulfide contained in the fuel spay , this must be paid more attention during refining; diesel oil fraction with high diesel index and large cetane value, its cor- rosion and acidity all meet product standards. VGO with smaller value of acidity, and high viscosity index is an ideal raw materials for producing lubricant, while its high Cp, low carbon residue, low heavy metal con- tent made it also ideal as catalytic cracking feedstock; 〉 520℃ reside has high asphaltene content and is an ideal raw material for asphalt production, if it is used as catalytic cracking feedstock, allocation ratio must be considered to prevent catalyst poisoning.
