摘要
以自由基聚合的方法合成聚环氧琥珀酸钠,并将其用作一种油田管道防垢剂。研究了各合成条件对聚环氧琥珀酸钠防垢性能的影响,得到了合成聚环氧琥珀酸钠的最佳工艺条件。同时进行了不同投加量的样品防垢性能测试,结果表明:在合适的投加量下,自制样品对硫酸钡垢、硫酸锶垢的防垢率可达99%,最后,初步探讨了聚环氧琥珀酸钠的防垢机理。
Polyepoxysuccinic acid（PESA）was synthesized in virtue of free radical polymerization, which is used as oilfield inhibitor. The effects of synthesis conditions on the performances of PESA were discussed and the optimal process condition was obtained. The scale inhibition performance of synthesized sample with different dosage was also tested. The results show that： with the appropriate amount, the inhibiting rate of barium sulfate scale and Strontium sulfate scale reached 99%. The mechanism of its scale inhibition was also primarily discussed.
