Starch Reagents PolyKR

These reagents are intended for regulating the filtering characteristics of and stabilizing process fluids used in drilling. The series of starch reagents includes the following products: PolyKR-F, highly resistant to Ca and MG salts; PolyKR-K, with a strong thickening capacity; PolyKR-D, with moderate viscosity properties.

Application

Starchy reagents PolyKR are easily soluble in fresh, sea, and saline water and allow regulating process fluid parameters at temperatures of up to 100°С. The optimal process properties of drilling fluid are attained after its thermal treatment at 80–90 °C.

 

Processing

The recommended consumption of PolyKR reagents ranges from 5 to 30 kg per cubic meter of drilling fluid.

 

Packaging

PolyKR are packaged in 25-kg polypropylene bags with a polyethylene liner.
