Conventional oil well cement cannot hydrate within 24 hours below 5 ℃. The conventional early-strength enhancer is difficult to achieve the desired early strength at this temperature and most contain chloride ion which has a strong corrosion to casing. ZOC-DA92S is a chlorine-free inorganic mixture, which has no corrosive effect on the casing and has a significant early-strength enhancing effect in the temperature range of 3 ℃ ~ 30 ℃ . It is suitable for cementing of deepwater surface casing.
Dry mixing or wet mixing, recommend wet mixing with pulp. Pulp water is sea water, or it can be fresh water.
Temperature is 3℃~120℃.
Recommended dosage：0.5~3.0% (BWOC).
Recommended to use with ZOC-DA93L.
Recommended to use with ZOC-DA93L, ZOC-DG72S and ZOC-GS12L in anti shallow stream cementing.
