GEOPOLYMER COMPOSITIONS AND METHODS

Geopolymer precursors are presented that are useful for subterranean wells. The precursors contain an aluminosilicate source, an alkali activator, and a carrier fluid. Additives are incorporated into the precursors to induce expansion, self-healing, flexibility, and to improve tensile and shear-bond...

Zusammenfassung:	Geopolymer precursors are presented that are useful for subterranean wells. The precursors contain an aluminosilicate source, an alkali activator, and a carrier fluid. Additives are incorporated into the precursors to induce expansion, self-healing, flexibility, and to improve tensile and shear-bond strength. L'invention concerne des précurseurs géopolymères qui sont utiles pour des puits souterrains. Les précurseurs contiennent une source d'aluminosilicate, un activateur alcalin et un fluide porteur. Des additifs sont incorporés dans les précurseurs pour induire une dilatation, une autorégénération, une flexibilité et pour améliorer la résistance à la traction et au cisaillement.
