摘　　要：化学降凝剂法操作简单、成本低且可以有效提高石油产品的低温流动性,是解决原油凝固点高、粘度大的较好的方法。本文合成了两种不同的三元共聚物以及三种不同的二元共聚物。将这些降凝剂用于新疆原油和吉林蜡油,测定降凝剂的降凝幅度,结果表明降凝剂的加入能有效地降低原油的凝点。Chemical pour point depressant method,featuring simple operation and low costs,can improve the fluidity of oil products at low temperature.It has been used to resolve the high freezing point and viscosity of crude oil.Two ternary copolymer and three binary copolymer were synthesized,which were used to reduce the pour point of Xinjiang crude oil and Jilin wax oil respectively.The results show that the addition of the depressants can reduce the freezing point of the crude oil efficiently.
