摘　　要：用引发聚合方法合成了一种耐温抗盐二元共聚物驱油剂———AMPS/AM。研究结果表明 ,在单体浓度为2 0 % ,AMPS∶AM为 1.0∶4.0 ,引发剂用量为单体总量的 0 0 3 0 %～ 0 0 5 0 % ,pH值为中性时 ,可以得到增粘效果较好的合成聚合物。它在矿化度为 1 6× 10 5 mg/L的盐水中可配成稳定的溶液 ,经 90℃ 90d热稳定试验后 ,该溶液粘度保持率仍较高。To seek Polymers for EOR in hostile reservoirs, the synthesis of acrylamide/2 acrylamido 2 methylpropane solfonic acid (AMPS/AM) bicopolymers by initiated ploymerization in aqueous solution is studied It is shown that bicopolymers in a 16% mixed salt solution can be reached with reacting mixtures containing 20% mourners and 0 03 %-0 05% initiator in neutral media (pH=7) in 6 hrs 0 3% bicopolymer solution in salt water has viscosity 34 4 mpa·s (25℃, 7 3s -1 ) and maintains enough viscosity (20 3mpa·s) after aging at 90℃ over 90 days
