摘要: |
本文介绍了一种用单体聚合包裹制成的微胶囊破胶剂,该破胶剂是利用包裹的水溶胀高分子膜的缓慢水化而释放出过硫酸铵,其缓速释放性能好、释放率高;在水基压裂液冻胶中加入该破胶剂,冻胶的抗剪切性能好,在50min的恒温、恒速剪切下,冻胶的粘度仍大于60mPa·S,8h后的破胶液粘度小于2mPa·S。 |

Abstract: |
This paper introduced a new micro-encapsulated gel breaker. This breaker made by a water swelling polymer can release its ammonium persulfate(APS) slowly because of hydration of polymer, in this process, APS goes out after water goes in through the polym |
