Friction Reducer for Cementing
Product Description :
USZ drag reducing agent (dispersing agent) can adjust the electric charge on the surfaces of cement particles to get proper cement rheology. As a result, it can reduce pump pressure, enhance drilling efficiency and used in construction easily.
Performance Characteristics :
- USZ is modified polymer which made up of methanal and acetone.
- The normal dosage is: 0.3% ∼ 0.8% USZ (BWOC), and it is not confined to this range in some particular case.
- Dissolve easily.
- Increasing additive dosage, it can adjust the rheology of the cement slurry effectively, and
reduce the consistency.
- With good high temperature resistance, it can be used within 30℃ ∼ 180℃ (BHCT).
- Consolidate cement stones, enhance its compression strength and control fluid loss.
- With certain retarding property.
- Mixed with or without water.
- Good compatibility with other additives.
