发明名称 EXTENDING LINES THROUGH, AND PREVENTING EXTRUSION OF, SEAL ELEMENTS OF PACKER ASSEMBLIES
摘要 A packer assembly can include an annular seal element and an end ring including leaves formed on a body of the end ring, whereby the leaves are biased radially outward when the seal element extends radially outward. A method of sealing an annulus in a subterranean well can include positioning a circumferential series of leaves radially outwardly overlying an annular seal element of a packer assembly, and the leaves pivoting radially outward in response to swelling of the seal element. Another packer assembly can include an annular seal element which swells in response to contact with a selected fluid in the well, and an end ring including an end ring body with a removable portion being engaged with the end ring body via interlocking profiles.
