Drilling fluid additives
AU-22 is for acidification or acid fracturing limestone construction. By the modified polyacrylamide composition,
rich in cations, has good acid resistance, heat resistance, water-soluble, acid soluble well, have a good
shear capacity, is an ideal thickner.
(1) Appearance: white viscous liquid;
(2) Density: 1.05 ~ 1.08g/cm3;
(3) PH value: 6.0 ~ 7.0;
(4) acid-soluble time: ≤ 30min;
(5) Rheology: 30 ℃170S-1 ≥ 25MPa.S;
(6) thermal stability: ≥ 90 ℃
(7) Shear Stability: Cut (170S-1) 120min ≥ 15MPa.S;
(8) compatibility: Good.
In the 20 ~ 28% HCL acid in the various additives, to be mixed, add 8 to 10% thickening agent can be mixed.
Then the acid according to the construction design pressure or acidification
200kg plastic drum.
