USZ Friction Reducer for Oil Well Cementing
description1
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.
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.
Soluble 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.
Technical Specification
The ratio of thickening time: refers to the ratio of thickening time of cement slurry with drag reducer to the thickening time of pure cement slurry.
The ratio of compression strength: refers to the ratio of the compression strength of cement stone with drag reducer to the thickening time of pure cement paste.
