Reliable Low-density Cementing System ( ReliCem )
-
ReliCem- ApplicationⅠ Low pressure and easily leaking formation.
Ⅱ Cementing at surface layer, intermediate and payzone formation.
Ⅲ Cementing in payzone with single low-density Cementing System.
Ⅳ Cementing in horizontal well or at inclined section.
-
ReliCem- Characteristics- Suitable for cementing in low temperature and easily leaking formation.
- The specific gravity can be controlled at 1.30～1.80g/cm³, with good rheology and easy operation on site.
- Low free liquid and reliable compressive strength of cement.
- Good stability, good compatibility with different brands and series of cement.
- Provides reliable cement strength and contributes to secure cementing quality.
