PRO-YAMOG3(F)-KU Axial Mechanical Set Packers with Integrated Hydraulic Anchor and Equalizing Valve (rated operating pressure up to 10 000 psi)

Your message sent

These packers are designed:

for sealed separation of casing string intervals and protection of the casing against the dynamic effect of various well operations;
to equalize the annulus pressure above the packer and the pressure inside the tubing string;
for pressure testing of the tubing above the packer.

DESCRIPTION APPLICATIONS

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:
