高 粘原油降 粘降凝 剂是由丙 烯酸二十 二酯、马 来酸酐、苯乙烯三 元共聚 物与非离子表 面活性剂 按一定 的质量比 复配成 的产物. 讨论 了聚 合物 中各 组分 的用 量比 、共 聚物 与表面 活性剂的 配比对 降粘效果 的影响 ,并在50 ℃、剪 切速率100 s - 1 条 件下对 粘度为5 500m Pa·s 的 高粘 原 油 进行 了 测试 ,当 加 剂量 为 04 % 时, 原油 凝 点下 降 12 ℃, 粘 度下 降 了567 % .
High viscous crude oil viscosity reducing pour point depressant is composed of behenyl acrylate, maleic anhydride, styrene terpolymer and nonionic surfactant by a certain mass ratio of the product. The effects of the amount of each component in the polymer and the ratio of copolymer to surfactant on the viscosity reduction were discussed. The viscosity of the copolymer was 5500 mPa · s at 50 ℃ and shear rate of 100 s - 1 The viscosity of crude oil was tested. When the dosage was 04%, the freezing point of crude oil decreased by 12 ℃ and the viscosity decreased by 567%.
