OIL WELL CEMENTING ADDITIVE FLUID LOSS ADDITIVE CG610S-P
SUMMARY
1.CG610S-P Fluid loss additive is a high efficient fluid loss additive with high purity and low dosage.
2. CG610S-P Fluid loss additive slurry system has wide applicable temperature range and it’s resistant to high temperature.
3. CG610S-P Fluid loss additive has salt resistance. It’s efficient in saturated brine.
4. CG610S-P FLuid loss additive slurry system is stable with little free fluid.
5. CG610S-P Fluid loss additive slurry system is not retarded, fast strength development.
6. CG610S-P Fluid loss additive slurry system has excellent rheological behavior. It generally doesn’t
require adding dispersant.
7. CG610S-P Fluid loss additive is suitable for dry mixed and water mixed, which is soluble in cold water.
8. CG610S-P Fluid loss additive can be made into dry-mixing type CG610S-D through mixed with mate-
rials such as slag, silica powder, fly ash; also made into dry-mixed water-mixed dual-purpose product
CG610S-T.The weight percentage of CG610S-P fluid loss additive is 40-60% when made into
CG610S-D and CG610S-T.
9. CG610S-P Fluid loss additive can be made into solution through mixing with water, which is liquid
product CG610 L, then the weight percentage of CG610S-P fluid loss additive is 20%-30%.
SPECIAL ATTENTIONS
1. CG610S-P Fluid loss additive dosage should be increased if being used in brine or high tempe-
rature system.
2. When CG610 L prepared with CG610S-P fluid loss additive is not used at once, preservative sh-
ould be added to extend expiration period.
APPLICATIONS
1.Temperature:Lower than 302°F (150°C) (BHCT) in fresh water system, lower than 356°F (180°C)
in brine system.
2. Dosage: CG610S-P fluid loss additive (high purity type) generally 0.8-1.8% (BWOC), recomm-
ended amount 0.9% (BWOC, in fresh water system, W/C=0.44).
