DESCRIPTION APPLICATION
- Recommended for multiple massive hydraulic fracturing in one round-trip in wells with the risk of complicated release after HF;
- for pressure testing and leak finding in the casing string;
- for pressure treatment of formations with chemical agents;
- for remedial works and other well operations which require generating high pressure difference across the packer.
ADVANTAGES
- enlarged passage bore of 50 mm for casing strings with the nominal diameter of 140-146 mm;
- reliable sealing of the production string in the course of operations which require generating high pressure difference across the packer;
- easy packer releasing without additional tensile load;
- long-term performance efficiency at high pressure differences up to 70 MPa and temperatures up to 150 °С;
- multiple use within one round-trip;
- high repairability.
DESIGN FEATURES
- packer design comprises a bypass which is open when the tool runs in and shuts off when the tool is set and a balancing valve;
- packer is set into the well mechanically by axial movements of the string (tubing rotation is not required) and brought into transit position by tensioning of the string;
- to equalize the pressure above and below the packer it’s sufficient to lift the tubing string at not less than 0.5 m;
- when the string is moved upwards the packer gets automatically released and goes back to its transit position;
- enlarged passage bore enables to pump a large volume of proppant during one trip-in operation;
- an integrated hydraulic anchor protected from contact with process fluid during pumping.
