聚合物稠油降凝剂的合成与性能研究

合成了丙烯酸高碳醇酯和马来酸高碳醇酯,并对聚丙烯酸高碳醇酯和聚马来酸高碳醇酯合成作用进行了研究.通过红外光谱对合成的单体及其聚合物进行了表征;研究了对泌安4001、安4003、安4004、325、泌304等稠油的降凝作用.结果表明:用量为500mg/L时聚丙烯酸十二酯、聚马来酸十六酯等对油样安4003、泌304的降凝作用较好,最大降凝幅度可达20℃;用量为250mg/L时聚丙烯酸十二酯对安4003降凝幅度为17℃,聚马来酸十六酯对泌304降凝幅度为16℃.

Synthesis of a poly-depressant for heavy oil and its performance

Polyacrylate(high carbon alcohol ester)and polymaleic acid(high carbon alcohol ester)are synthesized,and the synthesized monomers and polymers are characterized by IR.The pour depressing effect of polyacrylate(high carbon alcohol ester)and polymaleic acid(high carbon alcohol ester)to An 4001,An 4003,An 4004,325 and Bi 304 heavy oil are studied.The results show that,when the dosage of the depressants is 500 mg/L,all the polyacrylic twelve ester and polymaleate sixteen ester have better pour depressing effect on An 4003 heavy oil and Bi 304 heavy oil,and maximum pour point depressing can reach to 20 ℃;when the dosage of the depressants is 250 mg/L,the pour point depressing of polyacrylic twelve ester on An 4003 heavy oil is 17 ℃,and the pour point depressing of polymaleate sixteen ester on Bi 304 heavy oil is 16 ℃.
