The main compositions of fracturing fluids. It can made the fracturing fluids injected back into the oil layer and smooth the whole oil passages. It plays an important role in increase the exploit rate of oil well.

Characteristics:

1. Choose appropriate supplementary materials and neutral binder from many inorganic salts and make granulation of ammonium persulphate.

2. Use advanced nodulizing equipment to make fine pellets.

3. Arrange high-molecular materials in proper proportions to make some materials, which can sustained-release and hydrate totally while staticallly

4. Use advanced boiling fluidized bed equipment to coat breaker in order that the coating menbranes can be in good shape and have the same thickness. In this way, the encapsulated breakers are consistent when releasing and get good result in cracking.
