Oil Well Cement Slurry Admixture Dispersant
G-FS polymer dispersant powder is modified by polymerization of acrylic acid grafted polyether. Through directional adsorption on the surface of cement particles, the surface of the cement particles is charged with the same electric charge, forming electrostatic repulsion, and making the cement particles Disperse each other, destroy the flocculation structure of the cement slurry, and release the wrapped water to participate in the flow, thereby increasing the fluidity of the cement slurry, achieving the purpose of reducing pump pressure, improving displacement efficiency, and facilitating construction.
Product Description
Overview
1. G-FS is polymerized and modified from acrylic, polyether and other raw materials.
2. The dosage of G-FS is 0.3%-0.5% (BWOC), if there is a special purpose, it is not restricted by this range.
3. The rheology of cement slurry can be effectively adjusted as the dosage increases, and the consistency of cement slurry can be reduced.
4. Good resistance to high temperature, can be used at 30ºC-150ºC (BHCT).
5. Increase the compactness of cement stone and improve the compressive strength.
6. Has a certain retarding effect.
7. G-FS is easily soluble in water and can be wet mixed.
8. Good compatibility with other additives, suitable for dry mixing, and no special requirements for the water quality of the slurry.
