G302 Fluid Loss Control Additive for Oil Well Cement
G302 can control fluid loss though forming tight polymer film and enhancing viscosity of water phase.
CHARACTERISTICS
G302 consists of water-dissolved macromolecules and other related additives.
Appearance: Flowbility powder or particles, non-poisonous and non-odor.
Normal dosage: 0.8%~2.0%(BWOC),that makes API fluid loss less than 150ml.
Used in oil wells whose circulate temperature is between 40ºC~120ºC, and combined with
retarder.
Has no harmful influence on compression strength.
Preferred to mix without water.
