Metal to metal seal for use in well plugging applications, and associated methods |
摘要 |
A plug is provided for use in well plugging applications. In a described embodiment, the plug has a metal to metal seal on a hollow spherical structure. A change in contact pressure between the seal and a bore due to a change in differential pressure across the plug is regulated by changing characteristics of the plug structure.
