Methyl ester sulfonate (MES) is an anionic surfactant derived from natural oils. Polymers are large molecules composed of many repeated units that increase viscosity as a mobility control. Therefore, polymer and surfactant can be reacted into one substance as an alternative for enhanced oil recovery (EOR) application. The principle of this research is to graft sulfonate groups from MES into the polymer chain. Based on the experiments, the best result of polymerization was obtained at a mole ratio of 1:0.3 MES to acrylamide. Based on the interfacial tension (IFT) measurement, the IFT value decreased from 8.6 to 2.3 mN/m before and after the addition of polymeric surfactant respectively. The synthesis of polymeric surfactant obtained a yield of 1384.79%. Polymeric surfactant is potential candidates to change the initial oil-wet state of the quartz surface to water-wet based on wettability alteration study. According to thermal analysis and emulsification behavior, this polymeric surfactant was thermally stable under the desired reservoir temperature and was able to emulsify crude oil. The adsorption study showed that the adsorption onto the rock surface increased when the polymeric surfactant concentration was increased in the system. Core flooding experiments showed an increase in oil recovery in different concentrations of polymeric surfactant. Although the IFT value of polymeric surfactant is not very low, it has the potential as an alternative surfactant for EOR applications.

以棕榈油甲酯为原料合成聚合物表面活性剂用于提高采收率

甲酯磺酸盐 (MES) 是一种衍生自天然油的阴离子表面活性剂。聚合物是由许多重复单元组成的大分子,可增加粘度作为流动性控制。因此,聚合物和表面活性剂可以反应成一种物质,作为提高石油采收率 (EOR) 应用的替代方案。这项研究的原理是将 MES 中的磺酸基接枝到聚合物链中。根据实验,在MES与丙烯酰胺的摩尔比为1:0.3时获得最佳聚合结果。根据界面张力(IFT)测量结果,界面张力值在加入聚合物表面活性剂前后分别从 8.6 mN/m 下降到 2.3 mN/m。聚合表面活性剂的合成收率为1384.79%。基于润湿性改变研究,聚合物表面活性剂是将石英表面的初始油湿状态改变为水湿状态的潜在候选者。根据热分析和乳化行为,这种聚合物表面活性剂在所需的储层温度下是热稳定的,并且能够乳化原油。吸附研究表明,当体系中聚合物表面活性剂浓度增加时,岩石表面的吸附量增加。岩心驱油实验表明,不同浓度的聚合物表面活性剂可提高采收率。尽管聚合物表面活性剂的 IFT 值不是很低,但它具有作为 EOR 应用的替代表面活性剂的潜力。这种聚合物表面活性剂在所需的油藏温度下是热稳定的,并且能够乳化原油。吸附研究表明,当体系中聚合物表面活性剂浓度增加时,岩石表面的吸附量增加。岩心驱油实验表明,不同浓度的聚合物表面活性剂可提高采收率。尽管聚合物表面活性剂的 IFT 值不是很低,但它具有作为 EOR 应用的替代表面活性剂的潜力。这种聚合物表面活性剂在所需的油藏温度下是热稳定的,并且能够乳化原油。吸附研究表明,当体系中聚合物表面活性剂浓度增加时,岩石表面的吸附量增加。岩心驱油实验表明,不同浓度的聚合物表面活性剂可提高采收率。尽管聚合物表面活性剂的 IFT 值不是很低,但它具有作为 EOR 应用的替代表面活性剂的潜力。岩心驱油实验表明,不同浓度的聚合物表面活性剂可提高采收率。尽管聚合物表面活性剂的 IFT 值不是很低,但它具有作为 EOR 应用的替代表面活性剂的潜力。岩心驱油实验表明,不同浓度的聚合物表面活性剂可提高采收率。尽管聚合物表面活性剂的 IFT 值不是很低,但它具有作为 EOR 应用的替代表面活性剂的潜力。
