G34S Fluid Loss Control Additives for Oil Well Cementing
description1
Product Description
G34S belongs to pure polymerization and water-soluble agent , reduces the slurry cake permeability by the aggregation of water-soluble high polymer molecular chain. And a variety of functional groups are introduced into the polymer to enhance the anti high temperature property and salt resistance.
Characteristics
G34S is polymerized by AMPS, low molecular amide, auxiliary solvent,etc.
Anti temperature property: 30~200℃.
Anti salt property:fresh water until saturated brine.
Water solubility:dissolved in water easily.
Filtration property: ≤80ml API FL.
Generally dosage range: 0.5~1.5% (BWOC).
Good compatibility with other additives.
Compatibility with cement: suitable for all levels of oil well cement.
The cement slurry thickening transition time is short, close to right angle thickening.
Suitable for low, conventional and high density cement slurry system.
Technical Specification
The ingredient of the cement in the table is: G class cement, W/C: 0.44,water quality: distilled water,
G34S dosage: 0.8%, Density of slurry cement: (1.90±0.01)g/cm3.
G34S dosage: 0.8%, Density of slurry cement: (1.90±0.01)g/cm3.
