摘　　要：疏水缔合聚合物分子间可产生具有一定强度而又可逆的物理缔合 ,使聚合物体系具有良好的增粘、耐温、耐盐、抗剪切特性。在文、卫、马油田的高温高盐油藏条件下 ,对缔合聚合物性能进行评价 ,并与HPAM、AMPS聚合物进行对比。结果表明 :缔合聚合物体系具有良好的抗温、抗盐及剪切恢复性能 ,在 95℃、30 5块注入污水配制条件下和75℃、95块注入污水配制条件下 ,15 0 0mg/l浓度时的体系粘度可达到 11.6mPa·s和 16 .5mPa·s;缔合聚合物具有理想的抗Fe3 + 离子的作用 ,不必考虑配制容器和注入设备产生的Fe3 + 离子对聚合物溶液粘度的影响 ;在同浓度下 (>10 0 0mg/l) ,与聚丙烯酰胺、AMPS聚合物常温增粘特性相比 。Hydrophobic associating polymer systems have better properties in viscosity increase, temperature, salt and shearing resistance because there is some physical association with strength and reversibility between molecules of the polymer. Under the conditions of high temperature and salt reservoir in Wen? Wei? Ma oilfield, we evaluate performance of the associating polymer and compare with HPAM and AMPS. Results show that the system of the associating polymer has better properties in temperature and salt resistance and shearing recovery. In 95℃, formulated by 305 Kuai injecting waste water and in 75℃, formulated by 95 Kuai injecting waste water, when the concentration is 1500ml/l, the viscosity of the system can reach (11.6)mPa.s and 16.5mPa.s. In addition, the associating polymer has perfect action on Fe^(3+) resistance, so we needn't consider the influence of Fe^(3+) produced by formulating container and injecting equipment on polymer solution viscosity. At the same concentration (>1000mg/l), comparing with thickening properties of polyacrylamide and AMPS in normal temperature, the viscosity of the associating polymer is higher than the formers two orders of magnitude.
