Title
(DE) PUMPBARE GEOPOLYMERZUSAMMENSETZUNG FÜR BOHRLOCHDICHTUNGSANWENDUNGEN
(EN) PUMPABLE GEOPOLYMER COMPOSITION FOR WELL SEALING APPLICATIONS
(FR) COMPOSITION GÉOPOLYMÈRE POMPABLE POUR APPLICATIONS D'ÉTANCHÉIFICATION DE PUITS
Abstract
(EN)
Three pumpable geopolymer compositions for well sealing application is disclosed herein. One pumpable geopolymer composition comprises: (i) less reactive aluminosilicate; (ii) more reactive aluminosilicate; (iii) alkaline silicate activator solution with a very low S1O2/M2O. Another pumpable geopolymer composition comprises: (i) less reactive aluminosilicate; (ii) more reactive aluminosilicate; (iii) alkaline silicate-free activator solution that may contain an alkali salt; and (iv) powdered alkali silicate glass. The third pumpable geopolymer composition comprises (i) less reactive aluminosilicate; (ii) more reactive aluminosilicate; (iii) alkaline low silicate activator solution; and (iv) powdered alkali silicate glass.

L'invention concerne trois compositions géopolymères pompables destinées à être utilisées pour l'étanchéification de puits. Une composition géopolymère pompable comprend : (i) un aluminosilicate peu réactif; (ii) un aluminosilicate plus réactif; (iii) une solution d'activateur à base de silicate alcalin présentant un très faible rapport S1O2/M2O. Une autre composition géopolymère pompable comprend : (i) un aluminosilicate peu réactif; (ii) un aluminosilicate plus réactif; (iii) une solution d'activateur exempte de silicate alcalin qui peut contenir un sel alcalin; et (iv) du verre de silicate alcalin en poudre. La troisième composition géopolymère pompable comprend : (i) un aluminosilicate peu réactif; (ii) un aluminosilicate plus réactif; (iii) une solution d'activateur à faible teneur en silicate alcalin; et (iv) du verre de silicate alcalin en poudre.
