Abstract
Cement compositions may comprise an aluminosilicate; a sodium aluminate, a calcium aluminate, a potassium aluminate, or a combination thereof; and water. In some cases, the cement does not include Portland cement. The cement may be used in a subterranean formation having corrosive components therein, wherein the set cement sheath is resistant to degradation from the corrosive components within the subterranean formation.
Claims13
A method comprising:
- introducing a cement composition into a subterranean formation having corrosive components therein, wherein the cement composition comprises:
- an aluminosilicate;
- a potassium aluminate at 20% to 80% by weight of the aluminosilicate;
- a fluid loss control additive comprising a copolymer of diallyldimethylammonium chloride and 2-acrylamido-2-methylpropane sulfonic acid;
- and
- water;
- and
- allowing the cement composition to set to provide a set cement sheath;
- wherein the set cement sheath is resistant to degradation from the corrosive components within the subterranean formation.
A cement composition comprising:
- an aluminosilicate;
- a potassium aluminate at 20% to 80% by weight of the aluminosilicate;
- a fluid loss control additive comprising a copolymer of diallyldimethylammonium chloride and 2-acrylamido-2-methylpropane sulfonic acid;
- and
- water;
- wherein the cement composition does not include a Portland cement.
A method comprising:
- introducing a cement composition into a subterranean formation, wherein the cement composition comprises:
- a metakaolin;
- a secondary aluminosilicate;
- a potassium aluminate at 20% to 80% by weight of the aluminosilicate;
- a fluid loss control additive comprising a copolymer of diallyldimethylammonium chloride and 2-acrylamido-2-methylpropane sulfonic acid;
- and
- water;
- and
- allowing the cement composition to set to provide a set cement sheath;
- wherein the set cement sheath does not contain a Portland cement.
