Introudction of Full Bore Retrievable Packer
The Full Bore Retrievable Packers is also named
Halliburton RTTS packer, that is a full-opening, hookwall
packer used for well testing job, treating operation, and squeeze
cementing operations. Normally, the RTTS packer is run in the hole
with a circulating valve assembly.
The RTTS packer is the mechanical setting packer, the main body of
the RTTS packer includes a J-slot
mechanism, hydraulic slips, mechanical slips, and packer
elements. The RTTS packer is with large, heavy-duty slips in the
hydraulic hold down mechanism, wich can help prevent the tool
from being pumped up the hole. Drag springs operate the J-slot
mechanism on ≤ 3 1/2-in. (88.9-mm) packer bodies, while larger
packer sizes ≥ 4-in. (101.6 mm) use drag blocks. Automatic J-slot
sleeves are standard equipment on all packer bodies.
The full bore design of the RTTS packer allows unrestricted fluid flow and tool movement through the tubing bore, and this design permits pumping large volumes of fluid with a minimum pressure drop, and allows the passage of a through tubing type perforating gun.
Features and Benefits of the Full Bore Retrievable Packer
* Allows large volumes of fluid to pump through the RTTS packer.
* Tubing-type guns and other wireline tools can be run through the RTTS packer.
* The RTTS packer can be set and relocated as many times as necessary
* The RTTS packer have greater holding ability and improved wear resistance in high-strength casing by tungsten carbide slips
*An optional integral circulating valve locks into open or closed position during squeezing or treating operations, and opens easily to allow circulation above the packer.
