摘　　要：有些已被封堵的地层需重新解封,为此,对有机聚合物凝胶进行了降解试验研究。通过实验来研究破胶剂合成,得到最安全、最迅捷、最有效的破胶剂。H2O2的浓度越大,破胶越明显,并且温度越高,破胶能力越强。H2O2对木质素—聚丙烯酰胺冻胶体系破胶的结果较为理想,破胶后,剩余物较少。Some formation which have been sealed off need reset.Therefore,we have to research the organic polymer gelatin which is carried on the examination of degradation.By means of experiment we get the saftiest,the most effective,and the fastest gel breaker.The effect of viscosity break is better with the concentration of H2O2 incrersing,and the temperature incrersing.In the hydrogen peroxide solution broken Lignin-polyacrylamide gel＇s effect is very good. The remnant remains few after viscosity broke.
