发明名称 Downhole seal apparatus and method thereof
摘要 A method of forming a downhole seal between inner and outer tubulars. The method including bonding a sealing element to an insert with a bond that bonds at temperatures less than a first temperature and increasingly breaks down at temperatures higher than the first temperature. Defeating the bond between the sealing element and the insert at a second temperature higher than the first temperature; and, subsequently forming a seal between the inner and outer tubulars with the sealing element. Also included is a downhole sealing apparatus.

主权项 1. A method of forming a downhole seal between inner and outer tubulars, the method comprising: bonding a sealing element to an insert with a bond that bonds at temperatures less than a first temperature and increasingly breaks down at temperatures higher than the first temperature; defeating the bond between the sealing element and the insert at a second temperature higher than the first temperature; and, subsequently forming a seal between the inner and outer tubulars with the sealing element including axially actuating a swaging cone of the first tubular relative to the insert, and axially actuating the swaging cone includes deforming the insert and sealing element radially outwardly.
