摘　　要：我国原油 80 %以上属于石蜡基原油 ,适合生产高等级道路沥青的稠油资源相对较少。而辽河油田曙一区超稠原油密度大 ( ρ2 0 =0 .9977g .cm- 3) ,粘度很大 (υ1 0 0 =12 2 3 .9mm2 .s- 1 ) ,碳氢比高 ,无汽油馏分 ,柴油馏分收率仅为 7.19% ,其性质类似一般原油的渣油馏分。此原油蜡含量低 ,胶质和沥青质含量高 ,属低硫环烷基原油 ,是生产道路沥青的优质原料。而辽河油田现将此油经乳化后作烧火油使用。但是由于此油粘度极大 ,乳化后不易雾化 ,燃烧并不充分。为合理利用此石油资源 ,缓解当前我国高等级道路沥青供不应求的局面 ,我们采用辽河油田曙一区超稠原油作原料 ,选取炼厂贫蜡富芳废油作改性剂 ,可调合研制出符合GB5 0 0 92 -96标准的各种牌号的重交通道路沥青。并就调合沥青和国内外 4种沥青性质作了比较。实验结果表明 。More than eighty percent of the crude oils in China belong to paraffine-base oil, so viscous crude oil which is suited to be used as feedstock to produce high grade paving asphalt is less .The characteristics of the high viscous crude from No.1 Shuguang Zone of Liaohe Oil Field is similar to that of residue distillates of general crude such as high density(ρ 20 =0.997 7 g·cm -3 ),high viscidity (υ 100 =1 223.9 mm 2·s -1 ) and high carbon/hydrogen ratio. It contains no gasoline distillate and diesel yield is only 7.19%.This oil contains less wax,but rich in resin and asphalt,which belongs to low sulfur paraffine-base crude oil and can be used as feedstock to produce high grade paving asphalt.Now it is used as fuel after emulsificating. But this oil is so viscous that it can not be atomized uniformly and burned fully.In order to make full use of this oil and resolve the problem of paving asphalt demand-supply,various paving asphalts conforming to GB50092-96 standard were produced by blending vacuum residue of the high viscous crude from No.1 Shuguang Zone of Liaohe Oil Field and waste oil which is rich in aromatics and poor in wax. The results show that modified paving asphalts have good low-temperature properties and antiaging feature.
