High Pressure Full Bore Retrievable Packer / 7 inch RTTS Packer For
DST Tools
The Full Bore Retrievable Packer is a full opening, hookwall
type packer which is similar with RTTS Packer in Halliburton. The
full bore retrievable packer can segregate bidirectional
pressure designed for use in drill stem testing, treating, and
squeeze cementing operations. The full opening of the retrievable
packer permits pumping large volumes of fluid with a minimum
pressure drop, and allows the passage of a through tubing type
perforating gun which helps make the packer usable for
multiple operations with one trip in the hole-such as perforate,
test, treat, squeeze, perforate, etc.
Generally, the full bore retrievable packer is composed of a
packer body assembly and circulating valve assembly. It may also
includes a safety joint. The packer body includes a J-slot
mechanism, mechanical slips, packing element, and hydraulic slips.
Large, heavy-duty slips are used in the hydraulic hold-down
mechanism and help prevent the tool from being pumped up the hole.
The packer is equipped with the drag block.
The full bore retrievable circulating valve can be locked
closed when the packer is unset to reverse fluid around the bottom
of the packer. The circulating valve is designed with full opening
allows tubing-type guns and other wire line equipment to pass
