Fluid Loss Control Additive for Oil Well Cement

Product Description :

G35S belongs to pure polymerization and water-soluble agent, reducing the slurry cake permeability by the aggregation of water-soluble high polymer molecular chain. At the same time, G35S introduces various functional groups into the polymer to improve the suspension properties of the cement slurry.

Performance Characteristics :

G35S is modified and polymerized by AMPS, low molecular amide, and Polyhydroxy carboxylic acid etc.

Temperature Range: 30 ~ 200℃.

Water solubility: soluble in water.

Generally dosage range: 0.5 ~ 1.0% (BWOC).

Good compatibility with other cementing additives.

Compatibility with cement: suitable for all classes of cement.

The cement slurry thickening transition time is short, close to right angle thickening.

Suitable for low, and conventional cement slurry system .

Excellent suspension performance in cement slurry.

Having a little retarding property to the cement slurry.
