摘要
A straddle packer has a floating auto-J sleeve that automatically shifts the straddle packer from a run-in condition to a stay-set condition after pumping of high-pressure fluid into the straddle packer in excess of a predetermined pump rate is terminated. In the stay set condition, packer elements of the straddle packer remain in sealing contact with a well casing or well bore into which the straddle packer has been run.
