1. Product introduction
This product is suitable for fluid loss reducer in oil-based and water-based drilling fluid system. It can form thin and tough mud cake, so that hydrophobic particles can effectively block micro cracks, so as to prevent rock hydration, reduce rock debris erosion and prevent collapse
2. Product performance index
| Item | PH | Moisture content, % | Sodium sulfonate content, % | Water soluble content, % | Oil soluble content, % | High temperature and high pressure filtration, ml/30min |
| requirement | 8-9 | ≤8.0 | ≥10.0 | ≥70.0 | ≥25.0 | ≤25.0 |
3. Purpose and function
It is mainly used as filtrate reducer in petroleum drilling fluid. The temperature resistance of the product reaches 200 ℃, which will not cause viscosity increase in water-based drilling fluid and can assist in the formation of mud cake.
4. Usage
The general dosage is 3-4%, which has strong compatibility with other drilling fluid materials.
