G33S Fluid Loss Control Additive for Oil Well Cementing
description1
Product Description
G33S reduces the permeability of the cement filter cake through the aggregation of water-soluble polymer molecular chains. By introducing multiple functional groups into the polymer, it enhances temperature and salt resistance.
Characteristics
G33S is polymerized by AMPS, low molecular amide, multi hydroxy carboxylic acid, auxiliary solvent,etc.
Anti temperature property: 30~200℃.
Anti salt property: fresh water until saturated brine.
Filtration property: ≤100ml API FL.
Water solubility: dissolved in water easily.
Generally dosage range: 1.0~3.0% (BWOC).
Good compatibility with other additives.
Compatibility with cement: suitable for all levels of oil well cement.
The cement is stable and the free liquid is close to zero
The cement slurry thickening transition time is short, close to right angle thickening.
Suitable for low, conventional and high density cement slurry system.
Having a little retarding property to the cement slurry.
Technical Specification
*The ingredient of the cement in the table is: G class cement, Dosage of G33S: 1.5% (BWOC), water-cement ratio: 0.44, Density of the cement slurry: 1.90±0.01g/cm3，Distilled water or drinking water.
