Abstract

A variety of systems, methods and compositions are disclosed, including, in one method, a method of cementing may comprise: providing a cement composition comprising: a hydraulic cement comprising Portland cement in an amount of about 50% by weight of hydraulic cement or less, water, and a phosphorylated amino polycarboxylic acid cement retarder; placing the cement composition in a wellbore; and allowing the cement composition to set. A cement composition, the composition comprising: a hydraulic cement comprising Portland cement in an amount of about 50% by weight of hydraulic cement or less; water; and a phosphorylated amino polycarboxylic acid cement retarder.

First claim

What is claimed is:

1. A method of cementing a portion of a wellbore comprising:
providing a cement composition comprising:
a hydraulic cement comprising greater than 50% of a pozzolanic cementitious material by weight of the hydraulic cement, wherein the hydraulic cement comprises less than about 50% Portland cement by weight of the hydraulic cement,
water, and
a phosphorylated amino polycarboxylic acid cement retarder;

placing the cement composition in a wellbore; and
allowing the cement composition to set.

2. The method of claim 1 , wherein the cementitious material further comprises cement kiln dust.

3. The method of claim 2 , wherein the pozzolanic cementitious material is selected from at least one of fly ash, silica fume, metakaolin, natural glass, and any combination thereof.

4. The method of claim 1 , wherein the phosphorylated amino polycarboxylic acid cement retarder is present in the cement composition in an amount of about 0.001% to about 5% by weight of hydraulic cement.

5. The method of claim 1 , wherein the phosphorylated amino polycarboxilic acid cement retarder has the general formula below:

wherein R 1 is selected from at least one of an alkyl group, an alkenyl group, an alkynyl group, a branched alkyl, a branched alkenyl, a heteroatom substituted alkyl group, an alkyl alcohol, an alkoxylated heterocyclic group, a cycloalkyl group, a heteroatom substituted alkenyl group, and any combinations thereof,
wherein R 2 is selected from at least one of an alkyl group, an alkenyl group, an alkynyl group, a branched alkyl, a branched alkenyl, a heteroatom substituted alkyl group, an alkyl alcohol, an alkoxylated heterocyclic group, a cycloalkyl groups, a heteroatom substituted alkenyl group, and any combinations thereof, and
wherein R 3 is selected from at least one of an alkyl group, an alkenyl group, an alkynyl group, a branched alkyl, a branched alkenyl, a heteroatom substituted alkyl group, an alkyl alcohol, an alkoxylated heterocyclic group, a cycloalkyl group, a heteroatom substituted alkenyl group, and any combinations thereof.

6. The method of claim 1 , wherein the phosphorylated amino polycarboxilic acid cement retarder is an N-Phosphonomethyl Iminodiacetic Acid.

7. The method of claim 1 , wherein the phosphorylated amino polycarboxilic acid cement retarder comprises a number average molecular weight of from about 185 to about 400 g/mol.

8. The method of claim 1 , wherein the cement composition is substantially free of Portland cement.

9. The method of claim 1 , wherein the cement composition further comprises a dispersant, wherein providing the cement composition further comprises:
storing the cement composition in a pumpable fluid state for at least about 1 day or longer; and
mixing a chemical set activator into the cement composition.

10. The method of claim 1 , wherein the cement composition further comprises a chemical set activator capable of inducing the composition to set into a hardened mass.

11. The method of claim 1 , wherein the cement composition further comprises an additional retarder.

12. The method of claim 1 , wherein the cement composition further comprises a strength retrogressive additive selected from at least one of coarse silica flour, fine silica flour, and any combination thereof.

13. The method of claim 1 , wherein the cement composition further comprises a fluid loss additive selected from at least one of cellulosic materials such as hydroxyethyl cellulose and carboxymethylhydroxyethyl cellulose, copolymers of 2-acrylamido-2-methylpropanesulfonic acid and acrylamide or N,N-dimethylacrylamide, graft copolymers comprising a backbone of lignin or lignite and pendant groups comprising at least one member selected from the group consisting of 2-acrylamido-2-methylpropanesulfonic acid, acrylonitirile, N,N-dimethylacrylamide, and any combination thereof.

14. The method of claim 1 , wherein the cement composition further comprises a viscosifying suspension additive selected from at least one of scleroglucan, carragenans, xanthan, welan, diutan gums, celluloses, hydroxyl ethyl celluloses, high molecular weight acrylamide polymers, acrylic acid-acrylamide co-polymers, acrylamide co-polymers, and any combination thereof.

15. A cement composition comprising:
a hydraulic cement comprising greater than 50% of a pozzolanic cementitious material by weight of the hydraulic cement, wherein the hydraulic cement comprises less than about 50% Portland cement by weight of the hydraulic cement;
water; and
a phosphorylated amino polycarboxylic acid cement retarder.

16. The composition of claim 15 , wherein the pozzolanic cementitious material is selected from at least one of fly ash, silica fume, metakaolin, natural glass, and any combination thereof.

17. The composition of claim 15 , wherein the phosphorylated amino polycarboxylic acid cement retarder is present in the cement composition in an amount of about 0.001% to about 5% by weight of the hydraulic cement.

18. The composition of claim 15 , wherein the phosphorylated amino polycarboxilic acid cement retarder has the general formula below:

wherein R 1 is selected from at least one of an alkyl group, an alkenyl group, an alkynyl group, a branched alkyl, a branched alkenyl, a heteroatom substituted alkyl group, an alkyl alcohol, an alkoxylated heterocyclic group, a cycloalkyl group, a heteroatom substituted alkenyl group, and any combinations thereof,
wherein R 2 is selected from at least one of an alkyl group, an alkenyl group, an alkynyl group, a branched alkyl, a branched alkenyl, a heteroatom substituted alkyl group, an alkyl alcohol, an alkoxylated heterocyclic group, a cycloalkyl groups, a heteroatom substituted alkenyl group, and any combinations thereof,
wherein R 3 is selected from at least one of an alkyl group, an alkenyl group, an alkynyl group, a branched alkyl, a branched alkenyl, a heteroatom substituted alkyl group, an alkyl alcohol, an alkoxylated heterocyclic group, a cycloalkyl group, a heteroatom substituted alkenyl group, and any combinations thereof, and
