SUMMARY  

  1. CG212 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 (1.2-1.6g/cm3) and normal density cement slurry with strong dispersity.
  3. Generate thickening effect on cement slurry, enhance its suspension stability and prevent sedimentation.
  4. The lightweight cement slurries applied with FLA CG212 products exhibit good thickening performance.
  5. Fast compressive strength development of set cement.
  6. Used below temperature of 180℃(356℉, BHCT).
  7. Applicable mixing water: from fresh water to salt-saturated water.
  8. Compatible with other additives.
  9. CG212 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.
