| 摘 要： | 分别采用碳十八直链醇、碳十六支链醇与丙烯酸合成烷基酯,将烷基酯再与顺丁烯二酸酐、苯乙烯聚合制备的三元共聚物,对辽河油田的高凝原油的降凝效果进行了评价,实验发现这两种聚合物对凝固点为30℃原油都具有较好的效果,降幅可达10℃左右,但对凝固点为41℃的原油较差分别为3℃和6℃。具有支链烷基结构的聚合物对原油的感受性较好,最佳降凝浓度小,降幅大。实验还发现,溶剂对石蜡的凝固点降低作用明显,但对高凝原油的凝固点降低作用甚微。

| Abstract: | Two kinds of high alcohol acrylates were prepared by octadecyl alcohol and hexadecyl branched alcohol,respectively.The polymers of depressants were prepared by maleic anhydride-styrene-higher alcohol acrylates.By using these depressants,the pour points of the Liaohe crude oils were lowered form 30℃ to 20℃.But,the performance of that for the 41℃ crude oil was poorer,lowered 3℃ and 6℃,respectively.The polymer with branded alkyl exhibits good performance and sensitivity to the high pour-point crude oil.The solvents influence notedly to the wax pour-point,but noteless to the crude oil. |
