Early Strength Additive for Oil Well Cementing

Product Description :

G209-L can change ion concentration in cement hydrate to accelerate the acting of C3S、C3A and forming of calcium aluminous stone. So it can densify the structure and enhance early strength.

Performance Characteristics :

  • G209-L main consists of inorganic compound.
  • Density:1.1 ~ 1.5 g/cm3.
  • Normal dosage: 1.5%~4.0% (BWOC).
  • Suitable temperature :28℃~110℃ (BHCT).
  • Suitable for low and conditional density cement slurry.
  • The strength of cement is more than 20 MPa after 24 hours.
  • Suitable for low density cement slurry of fly ash, normal oil well cement and low density cement slurry of glass micro-spheres.
  • Preferred to mix with water.
