SEALING DEVICES HAVING A NON-ELASTOMERIC FIBROUS SEALING MATERIAL AND METHODS OF USING SAME |
摘要 |
Sealing devices such as packers comprise a sealing element having one or more non-elastomeric fibrous sealing material layers formed by a plurality of fibers. The plurality of fibers may comprise one or more of natural material, metallic material, plastic material, or other non-elastomeric sealing material. The non-elastomeric fibrous sealing material layers may be formed by weaving the plurality of fibers, braiding the plurality of fibers, or forming a fibrous mass of the plurality of fibers. During operation, the non-elastomeric fibrous sealing material layers are radially expanded causing compression of the non-elastomeric fibrous sealing material layers. As a result, at least a portion of the air volume within the non-elastomeric fibrous sealing material layers is displaced by non-elastomeric fibrous sealing material causing the sealing element to engage a sealing surface, thereby forming a seal. |
