Damper Anchor for ESP АL-118
This fishing anchor is mounted as part of the downhole equipment together with the damper АGLА-118 (shock-absorber) immediately under the ESP. At the end of the lowering run, the damper anchor is installed by raising the production tubing by one meter and then lowering it gently until it catches on; during this lowering maneuver a cam movement will activate anchoring mechanism.
The rubber filled damper vibration absorber can be installed under the ESP to reduce operational vibration. During the removal of the downhole equipment the spring loaded slips of the anchor remain in constant contact with the casing. This will provide a secure restraining of the equipment from falling down in case of tubing failure during raising (removal). Further the damper helps damping down the impact of falling equipment.
