How to correctly operate non-magnetic drill collars to reduce unnecessary wear and tear

1. Uniform drilling and reducing drilling pressure: During directional drilling or composite drilling, the driller needs to evenly feed the drill to avoid sudden changes in drilling tool stress; And reducing the drilling pressure appropriately can also reduce the friction and fatigue damage of the downhole drilling tools.
2. Regular short tripping: In the inclined section of a large well, short tripping can damage the underground rock bed, reduce the continuous friction between drilling tools and rock debris, and lower the risk of wear resistance and fatigue damage.
3. Avoid eccentric wear and coaxiality deviation: Non coaxiality between the joint and the pipe body can lead to eccentric wear, which requires precise machining and measurement to ensure coaxiality; On site verification of repaired joint data is required, and unqualified products are prohibited from entering the well.
