Is the abnormal wear of drill rods (such as eccentric wear) related to the technical level of operators?

Date: Feb. 24, 2025

The abnormal wear of drill rods (such as eccentric wear) is indeed related to the technical level of operators, but it is not the only factor. The following is a specific analysis:
1. The impact of operator’s technical level
Improper operation: Insufficient technical proficiency may lead to operational errors, such as improper control of drilling pressure and speed, resulting in eccentric wear.
Improper equipment adjustment: Inexperienced operators may not be able to adjust the equipment correctly, resulting in uneven stress on the drill rod and exacerbating wear and tear.
Insufficient maintenance: Operators with lower technical skills may neglect the daily maintenance of equipment, increasing the risk of abnormal wear and tear.

2. Other influencing factors
Equipment quality: The quality of drill rods and drilling rigs directly affects wear and tear.
Geological conditions: Complex geological conditions (such as hard rocks and alternating soft hard formations) can exacerbate drill pipe wear.
Drilling fluid performance: Poor lubrication and cooling effects of drilling fluid can also lead to increased wear.
Drill string assembly: Unreasonable drill string assembly may cause uneven stress on the drill string, leading to eccentric wear.
3. Preventive measures
Train operators to improve their technical skills and ensure proper operation and maintenance of equipment.
Regular inspection: promptly identify and address potential issues.
Optimize drilling parameters: Reasonably adjust drilling pressure and rotation speed according to formation conditions.
Use high-quality equipment and drilling fluid: reduce the occurrence of abnormal wear and tear.
The technical level of operators is an important factor affecting abnormal wear and tear of drill pipes, but equipment quality, geological conditions, and other factors can also have an impact. By training, regular inspections, and optimizing operating parameters, wear and tear can be effectively reduced.
