案例分享 Cementing Australia's first offshore CCS appraisal well
First offshore CCS well in Australia achieves zonal isolation using the CO2-resistant EverCRETE system.
CemCRETE
Concrete-based oilwell cementing technology
Optimize slurry performance and mechanical integrity
CemCRETE concrete-based oilwell cementing technology increases the solids content of the slurry using particle-size distribution. Smaller particles fill the void between larger particles, requiring less water. This results in a cement slurry with improved flow properties and excellent set properties, such as permeability and strength. A lower water-to-cement ratio during mixing and pumping enables higher long-term performance.
CemCRETE technology offers
- more solids in your cement
- greater compressive strength
- reduced cement permeability
- greater resistance to corrosive fluids.
Standard cement slurries require water to fill the void between particles. CemCRETE slurries fill the interparticle void with more solids, giving superior cement properties.
