DST Tools RTTS Packer is a large-diameter mounted type packer that can seal bi-directional pressure, which was designed for formation testing, acidizing fracturing, plug cementing and other down-hole operations. The large diameter can pump over large volumes of fluid under small pressure drop and make it pass the through-tubing perforating gun. RTTS packer can thus be used for multiple operations during one trip in the hole. Generally, RTTS Packer is used with RTTS Circulating Valve. It may also includes a safety joint.
Each specification of RTTS packer includes a J-slot mechanism, mechanical slip, packing element and hydraulic anchor mechanism. The hydraulic anchor mechanism can help prevent the packer from being pumped up the hole when too much pressure in the bottom of the packer. In addition, all packers are assembled with friction blocks and automatic J-slot sleeves.
1. Full-opening design of the packer mandrel bore allows large volumes of fluid to pump through the tool.
2. Can be set and relocated as many times as necessary with simple tubing manipulation.
3. Tungsten carbide slips provide greater holding ability and improved wear resistance in high-strength casing.
4. Optional integral circulating valve locks into open or closed position during squeezing or treating operations and opens easily to allow circulation above the packer.
