Abstract

The retrievable packer system includes a packer mandrel, a lock ring, an upper cone, a lower cone, a slip device, a retrieval mandrel, and a slotted retrieval sleeve. The lock ring is attached to the packer mandrel, followed by the upper cone, the slip device, the lower cone, and the retrieval mandrel. The upper connection sleeve and the lower connection sleeve cover the packer mandrel so as to form a chamber in fluid connection with slip flow channels of the slip device. The packer system is run into the borehole with the slotted retrieval sleeve in the first position relative to the lower cone and the slip device in the run-in position. The packer system is set and can be locked at a location in the borehole. The slotted retrieval sleeve can push the upper cone to return the slip device to the run-in position for retrieval of the packer system.
