چکیده انگلیسی
In this study the Influence of fine mineral additives such as zeolite tuff, metakaolin, microspheres and fly ash on the properties of light-weight oil-well cement was investigated. Strength, physical and performance requirements of light-weight oil-well cements were determined. The results have shown that the most effective facilitating additive which gives the lowest density is the microsphere. However, at raised pressures, it has been revealed that walls of the grains of the microspheres do not withstand a pressure of more than 20 MPa, and thus they will be destroyed leading to an increase in the density of the slurry and significantly limits the permissible depth for using this composition. On the other hand, it was found that using zeolite in combination with metakaolin improves the physico-mechanical properties of the oil-well cement stone.
