The present invention generally relates to a method and apparatus for sealing an annulus in a wellbore. In one aspect, the apparatus is an anchoring and sealing system for a downhole tool such as a bridge plug, packer, or frac-plug. The sealing system comprises of a sealing member disposed between a set of energizing rings, a set of expansion rings adjacent each cone, a set of support rings, and a set of slips. The components of the sealing system are arranged such that, when compressed, the sealing member may expand radially into contact with a casing. In another aspect, the apparatus the invention provides for an apparatus that is a downhole sealing tool.

1. An anchoring and sealing system for use in a downhole tool, comprising:a compressible sealing member;a segmented ring member at each end of the sealing member, each segmented ring member having a tapered outer surface and a lesser tapered end portion at a larger end thereof for contacting a wellbore surface; anda slip member adjacent to each segmented ring member, the slip member radially movable outwardly along the tapered outer surface of the segmented ring member and into frictional contact with the wellbore surface. 2. The anchoring and sealing system of claim 1, further includes an energizing ring disposed between the segmented ring member and the sealing member. 3. The anchoring and sealing system of claim 2, further includes a deformable expansion ring adjacent to each energizing ring. 4. The anchoring and sealing system of claim 3, wherein each expansion ring comprises a flexible fiber filled material that flows at a predetermined temperature. 5. The anchoring and sealing system of claim 3, wherein each segmented ring member and energizing ring comprises an epoxy blend reinforced by glass fibers stacked in layers angled at about 30 to about 70 degrees. 6. The anchoring and sealing system of claim 3, wherein each segmented ring member includes one or more tapered wedges, whereby activating the anchoring and sealing system extends the tapered wedges into contact with an area of a wellbore. 7. The anchoring and sealing system of claim 6, wherein activating the anchoring and sealing system causes the expansion ring to flow and fill a gap between extended wedges. 8. The anchoring and sealing system of claim 7, wherein each energizing ring includes a tapered first surface and a substantially flat second surface. 9. The anchoring and sealing system of claim 8, wherein the second surface of each energizing ring acts upon the sealing member upon activating the anchoring and sealing system. 10. A downhole tool, comprising:a body; andan anchoring and sealing system disposed about the body, wherein the anchoring and sealing system comprises:a sealing member;an energizing ring member disposed at each end of the sealing member;an expansion ring adjacent to each energizing ring;a support ring adjacent to each expansion ring, wherein each ring member has a tapered outer surface and a lesser tapered end portion at a larger end thereof for contacting a wellbore surface; anda slip member adjacent to each support ring, whereby activating the anchoring and sealing system causes the slip member to move radially outward along the tapered outer surface of the support rings and the seal member to expand outward. 11. The tool of claim 10, wherein the energizing ring member comprises an epoxy blend reinforced by glass fibers stacked in layers angled at about 30 to about 70 degrees. 12. The tool of claim 10, wherein the body comprises an epoxy blend reinforced by glass fibers stacked in layers angled at about 30 to about 70 degrees. 13. The tool of claim 10, wherein the support ring comprises an epoxy blend reinforced by glass fibers stacked in layers angled at about 30 to about 70 degrees. 14. The tool of claim 10, wherein the expansion rings comprise a flexible fiber filled material that flows at a predetermined temperature. 15. The tool of claim 10, wherein the support ring includes one or more tapered wedges, whereby activating the anchoring and sealing system the tapered wedges engage into contact with an area of a wellbore. 16. The tool of claim 15, wherein activating the anchoring and sealing system causes the expansion ring to flow and fills a gap between the extended wedges. 17. The tool of claim 10, wherein the energizing rings includes a tapered first surface and a substantially flat second surface. 18. The tool of claim 17, wherein the second surface of the energizing ring acts upon the sealing member upon activating the downhole tool. 19. The tool of claim 10, wherein the tool is a bridge plug. 20. The tool of claim 10, wherein t he tool is a packer. 21. A method for sealing a wellbore, comprising:running a tool into the wellbore, the tool comprising:a body;a setting ring; andan anchoring and sealing system disposed about the body, the anchoring and sealing system includes:a sealing member;a energizing ring member at each end of the sealing member;a deformable expansion ring adjacent each energizing ring;a support ring including one or more tapered wedges; anda slip member adjacent each support ring;applying an axial force on the setting ring to cause the setting ring to move axially on the body and act against the slip member;compressing the sealing member to expand in contact with an area of the wellbore;urging the slip member radially outward along an outer surface of the support ring, whereby the slip member supports the sealing member;expanding the support ring and separating the one or more tapered wedges;deforming the expansion ring to fill the gaps between the one or more tapered wedges; andurging the energizing ring axially toward the sealing member. 22. The method of claim 21, wherein urging the slip member radially outward forces the slip member into contact with an area of the wellbore. 23. The method of claim 21, wherein the energizing ring member and the support ring comprises a filament wound composite material. 24. The method of claim 23, wherein the filament wound composite material comprises an epoxy blend reinforced by glass fibers stacked in layers angled at about 30 to about 70 degrees. 25. The method of claim 24, wherein deforming the expansion ring causes the expansion ring to create a collapse load on the energizing ring, thereby holding the energizing ring firmly against the body. 26. The method of claim 21, wherein the expansion ring comprise a flexible fiber filled material that flows at a predetermined temperature.
