3.Main applications
CMC used in fracturing fluid, drilling fluid and well cementing fluid as fluid loss controller and tackifier. It can
protect the shaft wall and prevent mud loss thus enhance recovery efficiency. It has the following characteristics:
- Excellent water retention even at low concentration.
- Excellent thickening effect.
- Good resistance to salt and temperature change.
- Imparts excellent rheological property.
