CUTTING BED IMPELLER

TECHNICAL SUMMARY

The cutting bed impeller (cutting bed broker) tool is a downhole drill string tool specifically designed for deviated wells to address the problem of excessive cuttings accumulation during drilling, particularly suitable for well inclination angles greater than 30°. This tool is an integral part of the drill string, consisting of a short, one-piece mandrel with no moving parts, offering superior mechanical performance compared to drill pipe. Its working principle is to remove the cuttings bed from the casing or open hole sections. The tool's shape is designed to agitate cuttings that easily settle from the drilling mud in high-angle well sections.
