Synthesis and design of polymer systems based on acrylamide for enhanced oil recovery (EOR) is essential for reservoirs with high salinity and high temperature conditions. The use of associative monomers or the modification of the polymers with hydrophobic functional groups represents a promising alternative that extends the use of chemical EOR. In this study, terpolymers based on acrylamide, acrylic acid and butyl methacrylate were synthesized and the rheological properties of aqueous solutions of the obtained polymers at different pH values, and salt concentrations were evaluated. The results show that at alkaline conditions the viscosity of aqueous solutions of a polymer synthesized with 68.6 wt% of acrylamide, 22.9 wt% of acrylic acid and 8.6 wt% of butyl methacrylate increases by a factor of more than 1,000 at a 3 wt% concentration. Also, all polymers with the hydrophobic modification showed higher viscosity in saline solutions compared to their acrylamide‐acrylic acid analogue.

包括疏水性共聚单体对丙烯酰胺-丙烯酸基共聚物流变学的影响

合成和设计基于丙烯酰胺的聚合物系统以提高采油率（EOR）对于高盐度和高温条件的油藏至关重要。缔合单体的使用或具有疏水性官能团的聚合物的改性代表了一种有前途的替代方法，可扩展化学EOR的使用。在这项研究中，合成了基于丙烯酰胺，丙烯酸和甲基丙烯酸丁酯的三元共聚物，并在不同的pH值下评估了所得聚合物水溶液的流变性，并评估了盐浓度。结果表明，在碱性条件下，浓度为3 wt％时，由68.6 wt％的丙烯酰胺，22.9 wt％的丙烯酸和8.6 wt％的甲基丙烯酸丁酯合成的聚合物水溶液的粘度增加了1,000倍以上。。也，
