| titleOfInvention | PETROL WELL CEMENTING LAYER |
| abstract | The present invention relates to a high performance cement comprising: - an aluminous cement whose alumina content is at least greater than 30%, - a microsilica with a particle size of between 0.1 and 20 m, the percentage of which is less than 35% by mass relative to the weight of cement, - mineral particles with a particle size of between 0.5 and 500 m, the percentage of which is less than 35% by mass relative to the cement, the percentage of these particles remaining less than the percentage of said microsilica , - a water-soluble polymeric thinning agent, the percentage of which is between 0.2 and 3.0% relative to the weight of cement, - a retarding agent to control the setting time of the slag, - water in an amount at more equal to 40% with respect to cement. |
