DESCRIPTION APPLICATIONS
- Recommended for multiple massive hydraulic fracturing in one round-trip;
- for pressure testing and leak finding in the casing string;
- for pressure acidizing.
ADVANTAGES
- packers contain expandable supports to prevent rubber seal elements extrusion into annulus which increases the reliability of sealing and relieves packers unsetting;
- enlarged passage of 53 mm for casing strings with nominal diameter of 140 to146 mm;
- reliable sealing of production string during operations requiring high pressure differential on the packer;
- easy to release without additional tensile loads;
- pressure testing seat in the top part of packer allows to carry out pressure testing of the tubing prior to well operations;
- an integrated mechanical equalizing valve reduces accident rate and allows:
- in case of hindered release of packer, to equalize pressure above packer and inside the tubing by tensioning the tool upwards in excess of the preset valve actuation force;
- in case packer gets stuck with the valve in the open position, to flush or kill the well.
FEATURES
- packer is equipped with an integrated hydraulic anchor to keep the packer from moving upwards which is actuated by generating pressure inside the tubing after setting of the packer;
- packer is set into the well mechanically by axial movements of the string (no tubing rotation required) and brought into run-in position by tensioning of the string;
- packer can be used multiply for one round-trip operation;
- packer’s equipped with an integrated equalizing valve used to equalize the annulus pressure above the packer and pressure inside the tubing string;
- equalizing valve is mechanically actuated by tensioning the tool upwards;
- actuation force for the equalizing valve is preset by the manufacturer upon the customer’s request;
- valve is closed by unloading the tool.

- Maximum differential pressure on the packer is 70 MPa. Packer setting load is 60 to 120 kN.
- Upon special request packer setting device can be equipped with two rubber sealing elements.
- The force required to actuate KU valve while tensioning the tool upwards is 1 to 6 tons. This value can be changed upon the Customer’s request.
- Equivalent diameter of KU valve side ports is 15 mm.
The packer is available in the following configurations:
