Glass Bead for Oil Well Cementing
Product Description :
CP-55 is a high-performance hollow glass bead, mainly used as reducing agent ( filling agent ) in the low density cement slurry .
Performance Characteristics :
- CP-55 is a high-performance hollow glass bead with light weight, large volume, low thermal conductivity, high compressive strength, good fluidity and stable chemical performance advantages.
- Appearance:White flowability powder.
- Normal dosage: 5%～30% (BWOC). Can be prepared for the cement slurry whose density is (1.1～1.7) g/cm³.
- CP-55 content decreases with the increase of he cement slurry density, while the water cement ratio also decreases. Thickening time, rheological property, free water content can meet the construction requirements.
- Preferred to mix without water.
