Downhole tools containing ductile cementing materials

1. A downhole tool for controlling the flow of a fluid in a wellbore, the downhole tool including a component, the component comprising:

about 15 wt. % to about 50 wt. % of a cementitious material;

about 20 wt. % to about 60 wt. % of an aggregate comprising sand, gravel, silica, slag, recycled concrete, glass spheres, limestone, feldspar, crushed stone, or a combination comprising at least one of the foregoing; and

about 0.1 wt. % to about 10 wt. % of a ductility modifying agent, based on the total weight of the component;

wherein

the ductility modifying agent comprises a metal fiber and an ionomer;

the ionomer comprises a polymer backbone formed from an ethylenically unsaturated carboxylic acid; and

the component is a molded component made from a composition comprising the cementitious material, the aggregate; and the ductility modifying agent.

2. The downhole tool of claim 1 , wherein the metal fiber comprises steel fiber or iron fiber.

3. The downhole tool of claim 1 , wherein the cementitious material comprises one or more of the following: Portland cement; pozzolan cement; gypsum cement;

high alumina content cement; silica cement; or high alkalinity cement.

4. The downhole tool of claim 1 , wherein the component further comprises one or more of the following: wollastonite; silica flour; silica fume; fly ash;

calcium carbonate; barite; hematite; ilemite; siderite; hydroxyapatite; fluorapatite; or chlorapatite.

5. The downhole tool of claim 1 , wherein the component comprises:

about 0.1 to about 8 wt. % of the metal fiber;

about 15 to about 50 wt. % of the cementitious material; and

about 20 to about 60 wt % of the aggregate, each based on the total weight of the component.

6. The downhole tool of claim 1 ,

wherein the downhole tool is a frac plug or a bridge plug.

7. The downhole tool of claim 1 , wherein the component comprises about 25 to about 40 wt. % of a cementitious material, about 5 wt. % to about 12 wt. % of silica fume, about 5 wt. % to about 15 wt. % of quartz powder, about 30 wt. % to about 45 wt. % of sand, about 0.5 wt. % to about 7 wt. % of a metal fiber, and about 0.1 wt. % to about 5 wt. % of a superplasticizer, each based on the total weight of the component.

8. The downhole tool of claim 1 , wherein the component is a frustoconical member; and the downhole tool further comprises:

an annular body having a flow passage therethrough;

a seal member carried on the annular body and configured to engage a portion of the frustoconical member; and

a bottom sub disposed about the annular body, and

wherein the frustoconical member is disposed about the annular body.

9. The downhole tool of claim 1 , wherein the component is a bottom sub;

and the downhole tool further comprises:

an annular body having a flow passage therethrough;

a frustoconical member disposed about the annular body;

a seal member carried on the annular body and configured to engage a portion of the frustoconical member; and

the bottom sub is disposed about the annular body.

10. The downhole tool of claim 1 , wherein the component further comprises an aqueous carrier in an amount of about 0.1 to about 30 wt % based on total weight of the component.

11. The downhole tool of claim 1 , wherein all solid particles in the component have a particle size of less than about 100 microns.

12. The downhole tool of claim 1 , wherein the component has a compressive strength of about 5 ksi to about 150 ksi.

13. The downhole tool of claim 1 , wherein the component has a compressive strength of about 20 ksi to about 60 ksi.

14. The downhole tool of claim 1 , wherein the component is a frustoconical member.
