摘　　要：注聚合物对油田进行开发是一种常用的提高油田最终采收率的三次采油技术。随着聚合物注入量的增加,聚合物固体颗粒将沉积在孔隙中,这些附着物将会干扰聚合物的继续注入。因此我们研制了TR-3型聚合物解堵剂,我们应用研究的成果进行了现场试验,截止到2004年12月底,共应用解堵剂12吨,累计施工4井次,成功4井次,施工工艺成功率100%。平均单井增注2400m^3,平均单井增注聚合物母液1300m^3,对应油井增油420吨,取得了较好的经济效益。同时挤注解堵剂解堵后,平均降低注聚压力1.2MPa。Injecting polymer is one common EOR technology for oil field to improvement oil field final oil recovery ratio.With increase of injected polymer,more polymer solid particle deposit among the holes,These adhere to thing interfere continuation of polymer pour into. So we develop Model HAL-1 polymer releasing agent and carry on the in situ test,By the end of July of 2003,used a 12 such agent,implemented 4 wells,Succeed 4 wells,the success rate is 100%. Average single well increase injection 2400m^3, single well increase injected polymer mother liquor 1300m^3 on average,corresponding oil well increase 420 tons oil,Have gotten better economic benefits.After Injecting releasing agent,reducinge injecting pressure 1.2MPas equally.
