Sand Anchor YaP-114-73-15, YaP-114-73-30, YaP-114-73-45

This sand anchor is designed to separate large sand particles from the oil flow during the operation of the SRP (sucker rod pump). It is mounted underneath the packer at lower end of the pump level position.

The anchor is operated on the principle of gravitational settling of particles in an upward fluid flow. Due to the low fluid flow velocity in the anchor sand cups section, the sand separates and falls into the bunker. The bunker is made up of tubing with a sealed lower end which is installed underneath the anchor.

The anchor operation (described above) has a low hydraulic resistance and allows long-term operation without sand penetration into the pump.

YaP-114-73-15 is used for gas production of up to 15 m3/day, YaP-114-73-30 is used for gas production of up to 30 m3/day and YaP-114-73-45 is used for gas production up to 45 m3/day.

The anchor cannot be serviced while in operational mode.
