| 摘 要： | 首先合成了一定分子量的聚丙烯酸,然后再分别连续投加山梨醇和硬脂酸,通过两步酯化反应合成了一种聚丙烯酸高碳醇酯衍生物油溶性稠油降黏剂———PAEH.研究了合成条件对产物降黏效果的影响,得出了最佳合成条件:丙烯酸、多元醇、硬脂酸的物质量比为1∶0.6∶0.6,合成温度110~115℃,合成时间5~7h.讨论了该降黏剂加量和温度对其降黏效果的影响.结果表明,当其浓度为0.8g/L,温度在42.5~50.0℃时,具有最佳降黏效果.PAEH稠油降黏剂生产工艺简单,产率高,对高稠原油降黏效果明显.

| Abstract: | Firstly, a polyacrylic acid with certain molecular mass is synthesized, then sorbic alcohol and stearic acid are added into it separately, and finally, an oil-soluble viscosity-reducing agent is obtained by two-step esterification reaction. The effects of the reaction conditions on the viscosity-reducing result of the product are studied, and the optimal reaction conditions are obtained: the substance mass ratio of polyacrylic acid to sorbic alcohol to stearic acid is 1∶0.6∶0.6; reaction temperature is 110～115 ℃; reaction time is 5～7 h. The effects of the dose of the viscosity-reducing agent and temperature on its viscosity-reducing result are also studied, the studied result shows that, it has the best viscosity-reducing result when its concentration in crude oil is 0.8 g/L and temperature ranges from 42.5 ℃ to 50 ℃. |
