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。
In this paper, a kind of microcapsule breaker made of monomer polymerization package is introduced. The breaker is used to release the ammonium persulfate by the slow hydration of the wrapped water-swellable polymer membrane, The release rate is high. When the gel breaker is added to the water-based fracturing fluid jelly, the anti-shear performance of the jelly gel is good. Under constant temperature and constant shear of 50 min, the viscosity of the jelly gel is still greater than 60 mPa · s, After the broken gel viscosity is less than 2mPa · S.
