Abstract

Cementing compositions including a di- or poly epoxide resin, and amine hardener, and a di- or polyfunctional alkylphosphonate ester fortifier and methods of using the cementing compositions such as in a subterranean zone penetrated by a well bore.

First claim

The invention claimed is:

(a) a di- or poly epoxide resin;
(b) polyoxypropylenediamine, wherein the polyoxypropylenediamine is present from 5 wt % to 15 wt % based on the total weight of the composition; and
(c) a di- or polyfunctional alkylphosphonate ester fortifier, wherein the fortifier is present from 3 wt % to 15 wt % based on the total weight of the composition;
wherein the di- or polyfunctional alkylphosphonate ester is one or more compounds selected from the group consisting of:
hexa(methyl or ethyl) 1,2,3-propanetriyltrisphosphonate;
tetra(methyl or ethyl) 1,x-phenylenebis(methylene)diphosphonate, wherein x=2-4;
tetra(methyl or ethyl) 1,x-naphthalenediylbis(methylene)diphosphonate, wherein x=2-8;
tetra(methyl or ethyl) 2,x-pyridinediylbis(methylene)diphosphonate, wherein x=3-6;
tetra(methyl or ethyl) 2,5-furandiylbis(methylene)diphosphonate;
tetra(methyl or ethyl) 3-alkyl-2,5-furandiylbis (methylene) diphosphonate; and
tetra(methyl or ethyl) 3-alkyl-2,5-thiophenediylbis (methylene) diphosphonate

(d) a density modifier;
wherein the glass transition temperature of the composition is increased by the presence of the fortifier from 15° F. to 50° F. compared to the identical composition without the fortifier, and
wherein the composition has a viscosity of at least 5 Bc to 90 Bc prior to curing, and
wherein the composition does not comprise any Portland cement.

2. The composition according to claim 1 , wherein
(a) the di- or poly epoxide resin is one or more compounds selected from the group consisting of an epichlorohydrin adduct of a bisphenol, an epichlorohydrin adduct of a novolac, an epichlorohydrin adduct of an alkyl diol, and an epichlorohydrin adduct of a cycloalkyl diol.

3. The composition according to claim 2 , wherein
(a) the di- or poly epoxide resin is one or more compounds selected from the group consisting of a bisphenol A epoxy resin, a bisphenol F epoxy resin, an epoxy novolac resin, a diglycidyl ether of an aliphatic diol, a diglycidyl ether of a polyethylene glycol, a diglycidyl ether of a polypropylene glycol, a cyclohexanedimethanol diglycidyl ether, a butanediol diglycidyl ether, trimethylolpropane triglycidyl ether, a hexanediol diglycidyl ether, N,N-diglycidyl-4-glycidyloxyaniline, 4,4′-methylenebis(N,N-diglycidylaniline), neopentyl glycol diglycidyl ether, resorcinol diglycidyl ether, tetraphenylolethane glycidyl ether, tris(2,3-epoxypropyl) isocyanurate, and tris(4-hydroxyphenyl)methane triglycidyl ether.

4. The composition according to claim 3 , wherein
(a) the di- or poly epoxide resin is a bisphenol A diglycidyl ether resin and/or a cyclohexanedimethanol diglycidyl ether.

5. The composition according to claim 1 , wherein the di- or polyfunctional alkylphosphonate ester fortifier is an ethyl or methyl ester.

6. The composition according to claim 1 , wherein the di- or polyfunctional alkyl phosphonate ester is one or more compounds selected from the group consisting of:

wherein R is methyl or ethyl; and
R′ is a C 1 -C 15 aliphatic or branched alkyl, which may be optionally substituted.

7. The composition according to claim 1 , where (a) the di- or poly epoxide resin is in an amount of from 20 wt. % to 90 wt. %, based on the total weight of the composition.

8. The composition according to claim 1 , wherein (b) the amine hardener is in an amount of from 5 wt. % to 75 wt. %, based on the total weight of the epoxy resin.

9. The composition according to claim 1 , wherein the density modifier is barite.

10. The composition according to claim 1 , further comprising:
(e) a silane coupling agent, and (f) a diluent.

11. An epoxide resin cement composition for use in a subterranean well, the composition comprising:
(a) 30 wt. % to 90 wt. %, based on the total weight of the composition, of a bisphenol A diglycidyl ether resin and/or a cyclohexanedimethanol diglycidyl ether;
(b) 5 wt. % to 15 wt. %, based on the total weight of component (a), of polyoxypropylenediamine;
(c) 3 wt % to 15 wt % based on the total weight of the composition, of one or more di- or polyfunctional alkylphosphonate esters selected from the group consisting of:
hexa(methyl or ethyl) 1,2,3-propanetriyltrisphosphonate;
tetra(methyl or ethyl) 1,x-phenylenebis(methylene)diphosphonate, wherein x=2-4;
