摘要:

通过多元高碳醇与甲基丙烯酸酯化、共聚和胺解,研制出新型胺解共聚物型超稠原油流动改进剂,将流动改进剂应用于辽河超稠油中,进行黏温性能测试和模型预测分析。实验结果表明由于胺解共聚物流动改进剂具有与稠油较为相似的结构组成,使得原油内部大基团溶解而促进原油流动,因而显示出对超稠油独特的降黏效果,平均降黏率50%,最高可达到80%以上。建立了原油黏度随温度变化的预测模型并进行了三维参数模拟,预测模型的相关性达到0.987

Abstract:

A new flow improver additive for super-viscous crude oil was prepared by esterification of polybasic high carbon alcohol with methacrylate and copolymerization and amination copolymers. The additives were used in Liaohe super-viscous crude oil. The viscosity-temperature property was investigated and a prediction model was regressed. The result showed that amination copolymers with similar structure of super-viscous crude oil could dissolve the huge polar groups to make the crude oil flow. Henceviscosity decline rate reached 50%with the highest above 80%. A viscosity-temperature prediction regression model was established and three-dimensional simulation was developed. The correlation coefficient of prediction regression model reached 0.987.
