Abstract
A well tool having an anchor device, straddle packers above and below a port and an internal valve which are operated by longitudinal motion in an inflatable packer device. The well tool anchor is armed by a hydraulic operated plug and set upon downward motion in a locating profile groove in a well bore. The tool when attached to a string of tubing can be filled with cement slurry and downward motion used to anchor the well tool in a profile groove in an inflatable packer; to set the straddle packers above and below an access port on an inflatable packer; and then to open a valve to admit cement slurry to the inflatable packer. After filling the inflatable packer with cement slurry, an upward motion is used to close the valve, unset the straddle packers and release the anchor to move to another location where the operation can be repeated. At the conclusion of operations, a circulation valve is opened by pressure to reverse out cement slurry from the tubing string.
