稠油降黏聚合物功能材料的合成与降黏性能研究

对含有苯环、吡啶环和酯基类稠油降黏聚合物的合成过程进行了分子动力学模拟计算。在此基础上,采用溶液聚合法合成了含有苯环、吡啶环酯基类稠油降黏聚合物功能材料,以傅里叶转换红外法(FTIR)、动态光散射法、凝胶色谱法(GPC)和热分析法(DSC)对所合成的聚合物进行了表征;以胜利油田稠油为对象,采用流变仪对其进行了降黏效果的研究。实验结果表明含有苯环、吡啶环酯基类稠油降黏聚合物在30℃,聚合物加量为463×10-6时,其表观降黏率为79%,表现出了含有苯环、吡啶环酯基类稠油降黏聚合物具有潜在的工业应用价值。同时通过SEM冷场发射扫描电子显微镜对加降黏剂前后原油的微观形貌进行了观察,由此对降黏机理进行...

A new functional polymer which derived from mixed ester,styrene,and 4-vinyl pyridine monomers was synthesized by solution polymerization and simulated by Materials Studio.When obtained,the polymer was characterized by Fourier transform infrared(FTIR) spectroscopy,dynamic light scattering(DLS),gel permeation chromatography(GPC),and differential scanning calorimetry(DSC).Later,it was added to ShengLi crude oils,and evaluated by scanning electron microscopy(SEM) and RS rheogoniometer,then the viscosity reduction mechanism was discussed.Results indicate that the polymer shows a good performance for the oil,and it is observed that the visbreaking rate is up to 79% at temperature 3
