用市售石蜡包埋过硫酸铵，制成了一种新型压裂液用微胶囊破胶剂。该剂粒径０．６—１．２ｍｍ，包埋率约９５％，有效含量约８０％。基于加有微胶囊破胶剂的蒸馏水电导率随时间的增大，在６０℃、７０℃、８０℃蒸馏水中测得该破胶剂的释放速度与美国哈里伯顿公司的商品微胶囊破胶剂Ｏｐｔｉｆｌｏ３基本一致。
Using commercially available paraffin-embedded ammonium persulfate, a new type of microcapsule breaker for fracturing fluids was made. The particle size 0.6-1.2mm, embedding rate of about 95%, the effective content of about 80%. Based on the increase of the conductivity of distilled water with microcapsule breaker, the release rate of the breaker at 60 ℃, 70 ℃, 80 ℃ in distilled water is similar to that of the commercial microcapsule breaker Optiflo 3 agents are basically the same.
