G208 Accelerator for Oil Well Cementing
description1
Product Description
G208 can stabilize and strengthen low density cement slurry through bridging and changing concentration of ion in cement slurry.
Characteristics
Mainly composed of inorganic early-strength materials.
No-toxic, odorless.
Normal dosage: 1.0%~5.0% (BWOC).
Suitable temperature: 30℃~90℃(BHCT).
Can decrease free fluid and volume contraction in low density cement slurry, stabilize and enhance the strength.
Obvious effects of early strength. The strength of cement is more than 6MPa after 24 hours.
Can be used in ultra low density cement slurry systems (1.65±0.01g/cm3).
Suitable for low density cement slurry of fly ash, normal oil well cement, and low density cement slurry of glass micro-spheres.
It can also play a better early strength effect in conventional specific gravity cement slurry.
Mixed without water.
Technical Specification
Test conditions: G class cement:floating beads: micro-spheres=100:10:5, According to the total solid content, the dosage of reinforcing agent G208 is 2.5%, the water cement ratio is 0.65, and the cement slurry density is 1.60 ± 0.01g/cm3, Water quality: distilled water.
