| 摘 要： | 部分水解聚丙烯酰胺凝胶在高温高矿化度下易脱水，稳定性差，封堵时间短，通过加入增黏剂和其他凝胶体系使体系抗温抗盐性增加，封堵性保持时间较长，适用温度为95—120℃。对其成交过程中的黏度变化进行研究，表明封堵剂的注入性良好，岩心流动实验结果表明其封堵率在98％以上。

| Abstract: | Partially hydrolyzed polyacrylamide gel is easy to be dehydrated under high temperature, high salinity, poor stability and short block. Through adding tackifier and other gels, the resistance to temperature and salt can be increased; the sealing can keep a long time under the temperature from 95 ℃ to 120 ℃. The change of viscosity during the process is studied, which shows that injection of blocking agent with good size can lead to blocking rate of more than 98%. |
