摘要
合成了丙烯酸高碳醇酯 ,并用其与顺丁烯二酸酐、苯乙烯进行了三元共聚得降凝剂A ,然后再和高级脂肪胺进行胺解反应得到高效原油降凝剂B ,在大港油田的原油中分别加入A和B降凝剂 2× 1 0 -4使原油凝固点分别下降 7℃和2 0℃。加入A和B降凝剂 2× 1 0 -4于任丘、大庆油田中也有明显的降凝作用。同时还对聚合、胺解条件进行了研究 ,当单体物质的量之比为 9∶1∶1在 80℃反应 7h后与高级脂肪胺进行胺解 ,降凝效果最好。
Higher alcohol acrylic esters were synthesized and polymerized with maleic anhydride and styrene to prepare the oil retarding agent A,next the product A was aminolyzed into the oil retarding agent B by high alkyl amines.When agents A and B were added to crude oil at Dagang oil field that a concentrations of 2×10 -4 respectively,the crude oil freezing point was lowered by 7℃ and 20℃ respectively.They had similar effect at Renqiu and Daqing in the meantime,the reaction conditions of the polymerization and the aminolyzation were studied,it was observed that when their molar ratio was 9∶1∶1 and the aminolyzation was proceeded at 80℃ for 7 hours,the retarding result was the best.
