Title (EN) PERMEABLE CEMENTS
(FR) CIMENTS PERMEABLES
Abstract: front page image
(EN)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.
(FR)La présente invention concerne une composition de ciment perméable qui comprend un coulis aqueux de ciment hydraulique renfermant une phase fluide dispersée non miscible dans l'eau, par exemple une huile ou un gaz, et une matière de particules creuses, laquelle matière de particules creuses étant une matière qui se désintègre en présence du ciment de façon qu'elle laisse des vides qui, avec la phase dispersée, créent une structure perméable dans le ciment.
