发布时间：2019-06-05 09:31
【摘要】：针对新疆稠油黏度大、流动性差的特点,合成了具有苯基和酰胺基的聚酯型MAS系列降黏剂,采用红外光谱仪(FTIR)对合成产物进行了分析表征,并对MAS系列降黏剂用于新疆稠油的降黏效果进行研究评定。结果表明,具有乙酸乙酯主链的MAS5和具有高碳丙烯酸酯(C_(18))主链的MAS4的降黏效果较好。MAS5中的酰胺基团可与稠油中的胶质沥青质发生相互作用;苯基会影响稠环芳烃之间的π-π作用力;乙酸乙酯主链可在沥青质聚集体周围形成溶剂化层减少沥青质分子的聚集,使得稠油的黏度降低。对MAS5合成条件进行优化,温度为50℃下,当MAS5的用量为600mg/L和1000mg/L时对稠油的降黏率分别为50.6%和53.7%,黏度从5180m Pa·s分别降低至391m Pa·s和335m Pa·s,对稠油的降黏效果明显。MAS5同时具有合成原料价格较低的特点,具有较好的工业应用前景。
[Abstract]:According to the characteristics of high viscosity and poor mobility of Xinjiang heavy oil, polyester MAS series viscosity reducer with phenyl and amino group was synthesized and characterized by infrared spectrometer (FTIR). The viscosity reduction effect of MAS series viscosity reducer in Xinjiang heavy oil was studied and evaluated. The results show that the viscosity reduction effect of MAS5 with ethyl acetate main chain and MAS4 with high carbon acrylic ester (C18) main chain is better. The amide group in MAS5 can interact with colloidal asphaltene in heavy oil. Benzene group affects the 蟺-蟺 force between polycyclic aromatic hydrocarbons, and the main chain of ethyl acetate can form a solvation layer around the asphaltene aggregates to reduce the accumulation of asphaltene molecules and reduce the viscosity of heavy oil. The synthesis conditions of MAS5 were optimized at 50 鈩，
