摘要： The present invention relates to a method of accelerating the compressive strength development and setting time of a cement slurry during a cementing operation for a wellbore. The method generally comprises the steps of preparing a cement slurry comprising a hydraulic cement and water at the surface; placing the cement slurry in the wellbore; adding an activator to the cement slurry in the wellbore; and allowing the cement composition to set, wherein the activator acts as a set accelerating agent and a compressive strength enhancing additive.

摘要： A permeable cement composition comprises an aqueous slurry of a hydraulic cement including a water-immiscible dispersed fluid phase, such as oil or gas, and a hollow particulate material, the hollow particulate material being one which breaks down in the presence of the cement so as to leave voids which together with the dispersed phase create a permeable structure in the cement.
