Superiority
GH-I can stick on the surfaces of cement hydrate to inhibit contacting between cement and water, also stick on the surfaces of crystal nucleons to prevent their enlarging. So it can retard hydrating of cement slurry.
Details
Characteristics
- GH-I consists of various kinds of compounds, such as cellulose derivative and hydroxycarboxylic
acid.
- Non-poisonous, non-odor, and non-corrosivity.
- Normal dosage: 0.1%~1.0% (BWOC). It is more efficient if it is used combining with USZ friction reducing additive when middle-deep well is cemented.
- It can reduce the consistency of cement slurry and improve the rheology.
- Generally used in oil wells whose circulate temperature under bore is below 110℃.
- Preferred to be mixed without water.
