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.

Claims

1. 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.

2. The method of claim 1, wherein the corrosive components comprise one selected from the group consisting of carbon dioxide, hydrogen sulfide, hydrogen chloride, carbonic acid, and mixtures thereof.

3. The method of claim 1, wherein the cement composition further comprises:

a catalyst to accelerate setting of the cement composition, a fluid loss control additive, a cement retarder, a dispersant, a defoamer, a weighting agent, or a combination thereof.

4. The method of claim 1, wherein the aluminosilicate is a metakaolin.

5. The method of claim 1, wherein the cement composition further comprises a pozzolan selected from the group consisting of fly ash, silica fume, granulated blast furnace slag, pumice, and calcined shale.

6. 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.

7. The cement composition of claim 6, further comprising one or more of a catalyst to accelerate setting of the cement composition, a fluid loss control additive, a cement retarder, a dispersant, a defoamer, and a weighting agent.

8. The cement composition of claim 6, wherein the aluminosilicate is a metakaolin.

9. The cement composition of claim 6, further comprising a pozzolan selected from the group consisting of fly ash, silica fume, granulated blast furnace slag, pumice, and calcined shale.

10. 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.

11. The method of claim 10, wherein the cement composition further comprises one or more of a catalyst to accelerate setting of the cement composition, a fluid loss control additive, a cement retarder, a dispersant, a defoamer, and a weighting agent.

12. The method of claim 10, wherein the aluminosilicate is a metakaolin.

13. The method of claim 10, wherein the cement composition further comprises a pozzolan selected from the group consisting of fly ash, silica fume, granulated blast furnace slag, pumice, and calcined shale.
