DESCRIPTION APPLICATION
- recommended for a long-term autonomous (without tubing) isolation of the production string interval that is leaking or has to be separated during the well production with the use of submersible pump as a part of two-packer BHA comprising the top PRO-YAVZHT or PRO-YAVZHT-S packer, bottom packer, IPM (or IPG) setting tool and a sludge trap;
- for a long-term autonomous (independent from connection to the tubing) isolation of casing string damaged interval;
- for pumping water into injection wells;
- for formation separation during multiple-zone production and multiple-zone injection;
ADVANTAGES
- packers contain expandable supports to prevent rubber seal elements extrusion into annulus which increases the reliability of sealing and relieves packers unsetting;
- ability to tension the tubing string after the packer is seated without breaking the sealed separation of the production string intervals;
- top mechanical anchor fixed against rotation in relation to its rod, enables to avoid unsealing of the autonomous packer when IPM mechanical setting tool is turned away from it;
- packers contain a bottom rod and bottom case and their flexible connection is pressure-tight which allows to use this packer in two-packer BHAs;
- packers are equipped with a wedge key which provides the transmission of the torque to the string or equipment below the packer;
- ease to release without additional tensile load;
DESIGN FEATURES
- packers don’t have the bottom anchoring device and they are designed to be seated against the bottomhole or another packer located below;
- packers contain a top mechanical anchoring device which is actuated at a certain value of the axial compression load generated by the weight of the load located above the packer;
- PRO-YAVZHT packer can be used multiply for one tripping operation;
- PRO-YAVZHT-S packer contains shear pins and their number selection provides the adjustable load for the initial setting when the packer is used as a top packer in a two-packer BHA;
- High repairability.

1PRO-YAVZH-T-S packers have shear pins with the adjustable setting load 8-16 t. The admissible tubing tensioning value after the packer is seated is preset by the manufacturer upon the customer’s request within the range of 50-120 kN (5-12t.).
2When placing an order for equipment for Т=150°С, please indicate Т150.
3At the stage of development and bench testing
4Standard configuration packer is equipped with a sub (for 114/118/122 packer sizes - the relevant sub nipple 102 × nipple 73, for 140/145 packer sizes – the relevant sub nipple 114 × nipple 89). Upon customer request the packer can be equipped with any other sub or a centralizer sub for connection to the tubing.
- Maximum pressure differential across the packer is 5076 psi.
- Packer setting load is 120-160 kN.
- Upon special request packer setting device can be equipped with two rubber sealing elements.
- Upon customer's request packers can be manufactured with other sizes.
