G303 Fluid Loss Control Additive for Oil Well Cementing
description1
Product Description
G303 can control fluid loss through forming right polymer film and enhancing viscosity of water phase.
Characteristics
Normal dosage: 0.8%~2.0% (BWOC).
Slight retarding effect.
Suitable temperature: 30~120℃(BHCT),With the increase of temperature, the dosage should be increased appropriately, and supplemented with necessary retarder to adjust the thickening time.
Low initial consistency and good rheology.
No harmful influence on compression strength.
Mixed without water.
Technical Specification
The ingredients of the cement slurry in the table are: G class cement, W/C 0.44, Dosage of G303: 1.8 % (BWOC), Water quality: distilled water.
