Hydrophobically associative polymers have been verified having enhanced oil recovery (EOR) potential. In this paper, a hydrophobically associative polyacrylamide functionalized with p‐sulfocalix[4]arene (denoted as SHPAM) was firstly prepared through redox free‐radical polymerization technique. Then, the water solubility, comprehensive properties, flowing behaviors, and displacement characteristics of SHAPM were investigated. Experimental results illustrated that SHPAM had benign water solubility, thickening ability, salt tolerance, temperature resistance, anti‐shearing performance, thixotropy, and long‐term stability. Also, SHPAM could reduce heterogeneity and extend sweep efficiency. Moreover, the adsorbed and retained SHPAM in porous media owned favorable viscoelasticity, which enhanced microscopic displacement efficiency. All the experiments results revealed that SHPAM has great applicable in enhancing oil recovery.

对-Sulfocalix [4]芳烃官能化疏水缔合聚丙烯酰胺：流动特性及其在提高采油率方面的潜在应用

疏水缔合聚合物已被证实具有提高的采油率（EOR）潜力。在本文中，用p-官能化的疏水缔合聚丙烯酰胺sulfocalix [4]芳烃（称为SHPAM）是首先通过氧化还原自由基聚合技术制备的。然后，研究了SHAPM的水溶性，综合性能，流动行为和位移特性。实验结果表明，SHPAM具有良好的水溶性，增稠能力，耐盐性，耐温性，抗剪切性能，触变性和长期稳定性。同样，SHPAM可以减少异质性并扩展扫描效率。而且，SHPAM在多孔介质中的吸附和保留具有良好的粘弹性，从而提高了微观位移效率。所有实验结果表明，SHPAM在提高采油率方面具有很好的适用性。
