WELL PACKER AND METHOD

摘要

An apparatus and method for installing and removing packer assemblies from a subterranean well (10) is presented. The packer assembly (20) has a stop (80) that prevents the seal assembly (40) from relaxing. The stop (80) is cut axially by use of a chemically reactive cutter device (110) lowered into the well (10) and activated by use of conventional wire line equipment. Once cut, the seal assembly (40) on the packer (20) is allowed to relax and can be removed intact from the well (10).
