OOC-G80S-A (High-temperature AMPS) Fluid Loss Additive
OOC-G80S-A is a kind of sulfonic fluid loss additive. It has characters like: anti-high temperature, anti-salt, quick strength development, few free water. The product is appropriate to be used in different kinds of water and cement. It is also a kind of widespread use product, which can be used in different kinds of cement slurry systems. OOC-G80S-A is not only applicable in freshwater cement slurry, but also applicable in salt water cement slurry.
-
Usage range
Temperature: ≤180℃ (BHCT).
Recommend dosage：0.6~ 1.0% (BWOC).
Applicable in every kind of cement slurry systems, which are composed by every grade of oil-well cement(defined by GB10238 or APISpec10A) and other additives(just like silicon powder, drift beads, flyash, bentonite, barite powder and hematite).
OOC-G80S-A can be used together with medium temperature retarder (OOC-H21L), high temperature retarder (OOC-H31L), early strength agent (OOC-A90S) and disperser (OOC-F41L), and can also be used alone.
-
Functions
It can decrease the fluid loss obviously. Generally less than 50ml. If increasing the dosage, fluid loss will less than 30ml.
Effective salt resistance. It can be used in saturated salt water.
Thickening time increases slightly as temperature increases in the temperature range of 70 to 90℃ . It has no influence on the strength of cement stone.
Not sensitive to dosage, no catastrophe point, safety in use.
