摘　　要：针对涠洲原油高含蜡特性,比较了室内合成的长链不饱和羧酸酯类降凝剂HYJ-08与市售7种降凝剂降凝效果,并探讨了影响加剂效果的因素。实验结果表明,涠洲原油最佳热处理温度为55℃,降凝剂HYJ-08最优加剂量为600 mg/L,原油凝点由加剂前的34℃降至18℃,且可使20℃时原油的粘度、屈服值下降率达90%以上。经不同速率降温、多次重复加热、长时间静置后证明加有降凝剂HYJ-08的原油具有较好的稳定性。According to Weizhou crude oil with the characteristics of high paraffin,the depressant effect of HYJ-08,a pour point depressant synthesized with long-chain unsaturated carboxylic ester and other materials,and another 7 commercial ones was compared,and the influence factors of additive effect were discussed.The experiments showed that the optimum heat processing temperature of Weizhou crude oil was 55 ℃,the optimal concentration of HYJ-08 was 600 mg/L,the pour point of crude oil was reduced from 34 ℃ to 18 ℃ and crude oil viscosity and yield value reduction rate was more than 90 % at 20 ℃.The crude oil adding HYJ-08 still had good stability after different rates of cooling,repeated heating,long time stewing.
