Our company improve the technology of coating directly by  oxide crystals ,and show a new technology originality which adding a variety of additives after crushing the oxide crystals and then re-granulated into spherical particles. After repeated practice of argumentation，our products’ performance and indicators is much better than the domestic similar common capsule gel breakers . The advantages of capsule gel breakers after spheroidizing treatment is as follow :

1.The enclosing of cyst wall is very dense;

2.The capsule coating ratio is improve greatly;

3.Capsule core is full isolated with the outside;

4.During the fracturing process construction fluid viscosity and viscosity retention get the maximum improvement ;

5.it can be used with high concentration;

6.After the fracturing fluid gel breaking, it can be discharged out of the well smoothly,and it would not influence the ability of carrying sand 、the ability of forming fissure and artificial fracture conductivity , it can reduced the damaging rate of core permeability greatly at the same time;

7.That capsule can control its gel breaking time effectively according with different circumstances, to maximum meet the requirements of the construction process.
