High temperature and high pressure cutting retrievable packer

Abstract

The application discloses a high-temperature and high-pressure cutting recyclable packer. The packer comprises an upper joint, an upper mandrel, a lower mandrel and a lower joint which are sequentially screwed from top to bottom, and further comprises an upper anchoring mechanism which is arranged on the upper middle part of the upper mandrel, a rubber sleeve sealing mechanism which is arranged on the middle part of the upper mandrel, a lower anchoring mechanism which is arranged on the lower middle part of the upper mandrel, a lower slip retreat-stop mechanism which is arranged between the upper mandrel and the lower anchoring mechanism, a setting mechanism which is arranged on the outer periphery of the lower part of the upper mandrel and the lower mandrel, a locking mechanism which is arranged on the outer periphery of the setting mechanism and a releasing mechanism which is arranged on the middle part of the lower mandrel. The packer has the advantages of reliable sealing in a high-temperature and high-pressure environment and high recycling efficiency of the recyclable packer.
