AI Technical Summary

Technical Problem

Existing technologies are ineffective at removing iron filings from drilling and workover fluids, leading to equipment damage and safety hazards. Furthermore, existing devices are prone to clogging and are difficult to maintain.

Method used

A drilling fluid filtering device for iron filings is designed. Electromagnets are arranged in an array in the fluid passage using an electromagnetic filter plate. The filter plate is fixed to the housing by a clamping device. The electromagnetic field of the electromagnets is used to attract iron filings, which can be quickly removed for cleaning.

Benefits of technology

It enables efficient filtration and rapid sampling and analysis of iron filings in drilling and workover fluids, reducing the risk of equipment damage and improving safety and ease of operation.
