摘　　要：对采自塔里木油田的牙哈凝析油进行了全面物性分析和评价。结果表明 ,其 35 0℃以前馏分收率高达 72 .5 4 %。其直馏石脑油馏分的收率为 2 9.76 % ,芳烃指数为 2 1.73,裂解时乙烯收率仅为2 6 .5 6 % ,但其芳烃收率指数为 5 6 .34,是优质的催化重整原料。牙哈凝析油直馏轻柴油馏分收率高达4 2 .78% ,其芳烃指数、特性因数分别为 18.16和 12 .2 6 ,是优质的裂解原料 ,乙烯收率高达 30 .37% ,三烯总收率为 4 7.94 %。牙哈凝析油的利用方案应为 :石脑油馏分宜作催化重整原料 ,而轻柴油馏分宜作为裂解原料。The properties Yaha's condensated oil from Tarim oil field are analyze d and evaluated comprehensively. The results show that the yield of the fraction lower than 350℃ is 72.54%. The yield of its naphtha fraction is 29.76% and BMC I is 21.73 ; the yield of ethylene by naphtha pyrolysis is 26.56% , but i ts index of aromatics yield is 56.34 , so it is an excellent catalytic refor ming feedstock. The yield of AGO fraction is 42.78%, and its BMCI and characteri zation factor are 18.16 and 12.26 respectively, so it's an excellent cracking fe edstock, the y ield of ethylene and three kinds of olefin by AGO pyrolysis are 30.37% and 47.94 % respectively. Utilization scheme that naphtha fraction is used for catalytic r eforming feedstock and the AGO fraction is used as cracking feedstock is put for ward for Yaha's condensated oil.
