Synthesis and Study of an AM/AA/SMA Hydrophobically Associating Polymer Used as Thickening Agent in Fracturing Fluids

  • 摘要: 疏水缔合聚合物具有独特的流变性、抗温和抗剪切性能,使其可以应用在油气开采领域。以甲基丙烯酸十八烷基酯(SMA)为疏水单体,以AM、AA为水溶性单体,采用胶束聚合法合成了疏水缔合聚丙烯酰胺(HAPAM)。实验确定了HAPAM的最佳合成条件,引发剂最佳用量为单体质量的0.3%,最佳pH值为6,最佳SMA用量为单体质量的0.4%,SDS的最佳用量为SMA质量的30%,链转移剂甲酸钠的最佳用量为2 mg/L。采用红外、荧光、紫外、旋转黏度计等仪器对产品进行分析,确定该HAPAM中存在疏水缔合基团,临界缔合浓度约为500 mg/L,产品具有较好的水溶性、增黏性和抗剪切性,其耐温性和抗盐性也较相同条件下合成的PAM有所改善。采用不同交联剂与该HAPAM进行交联反应,发现其与有机锆的交联性较好。分析认为该HAPAM存在作为压裂液稠化剂使用而进一步深入研究的重要意义。
