Temporary Blocking Agent
1) Introduction
The product is composed of biodegradable materials, which can form a dense plugging layer on the surface of the proppant or mixed with the proppant under a certain pressure to achieve the purpose of temporary blocking and returning.
2) Technical indicators
3) What it replaces
Other products can not be modified in degradation time
4) Advantages
Gradually degraded at 40-150℃,
Good blocking effect
Completely degradable
Controllable degradation time
5) Product Appearance
Temporary Blocking Ball
1) Introduction
The product is composed of degradable materials, which can be blocked at the holes under certain pressure, which can temporarily block the fracturing.
2) Technical parameters
3) What it replaces
Other products can not be modified in degradation time.
4) Advantages
Gradually degraded at 40-150℃,

Knot-Shape Temporary Blocking Agent
1) Introduction
The product is composed of degradable fibers, the degradation time ranges from 4-120 hours, the density is adjustable, and it can be effectively suspended in the fracturing fluid. The rope-knot temporary plugging agent can effectively block irregular perforations and reduce bridge plugging and replace the bridge plug with part or the entire wellbore, which saves costs and reduces construction risks.

5) Product Appearance
Oil-soluble Temporary Blocking Agent
1) Introduction
The oil-soluble temporary plugging agent is composed of composite materials. It does not change when it encounters water, and can be slowly dissolved in oil.
2)Technical parameters
3) What it replaces
Those products melt in low temperature.
4) Advantages
The higher the temperature, the faster the dissolution rate.
It has the characteristics of certain thermoplasticity
High plugging strength at formation temperature.
