AI Technical Summary

Technical Problem

Existing electric submersible pumps are prone to barium strontium scale buildup after prolonged operation under complex downhole conditions, leading to damage to the impeller guides. Existing scale prevention methods have limitations.

Method used

The system employs an downhole anti-scaling electric pump and separator system. The anti-scaling balls inside the screen tube come into frequent contact with the oil. The solid spheres, made of anti-scaling agents and scale inhibitors, are combined with magnetic and centrifugal forces to make the anti-scaling balls move irregularly in the screen tube, thus achieving chemical anti-scaling and preventing the formation of barium strontium scale.

Benefits of technology

It effectively prevents the formation of barium and strontium scale, improves the scale prevention effect of the system, increases the contact frequency between the scale prevention ball and the oil, adapts to different downhole environments, and extends the service life of the equipment.
