|
| Product name : Synthetic polymer Fluid Loss Additives |
| Item : CTI-16 |
| Details : |
INTRODUCTION
- CTI-16 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.
- Specially designed for lightweight cement slurry system (1.2-1.6g/cm3) and normal density cement slurry with strong dispersity.
- Generate thickening effect on cement slurry, enhance its suspension stability and prevent sedimentation.
- The lightweight cement slurries applied with FLA CTI-12 products exhibit good thickening performance.
- Fast compressive strength development of set cement.
- Used below temperature of 180℃(356℉, BHCT).
- Applicable mixing water: from fresh water to salt-saturated water.
- Compatible with other additives.
- CTI-16 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.
