SUMMARY

  1. CG214 fluid loss additive is a synthetic polymer which is capable of effectively reducing water loss filtering from the slurry to porous formation during cementing process.
  2. Specially designed for lightweight cement slurry system (1.0-1.6g/cm3) and normal density cement slurry with strong dispersity.
  3. Applicable in fresh water slurries, seawater slurries, and slurries containing 2% CaCl2.
  4. Enhance suspension stability, maintain good liquidity of cement slurries and prevent them from sedimentation.
  5. Thickening time decreases with increasing temperature, and the compressive strength of set cement develops fast.
  6. Help control gas migration during the setting of cement slurry.
  7. Used below temperature of 180℃(356℉, BHCT).
  8. Compatible with other additives.
  9. CG214 series consists of L-type liquid, L-A type anti-freezing liquid, S-P type high purity powder, S-D type dry-mixed powder and S-T type dual-use powder.
