Analysis of causes of drill pipe fracture and preventive measures

Drill pipe breakage refers to the accident where the drill pipe breaks during drilling operations. Drill pipe fracture is one of the most common accidents in drilling. It not only affects drilling operations, but may also cause serious casualties and equipment losses. Therefore, it is very important to analyze the causes of drill pipe fracture and formulate preventive measures.

Reasons for drill pipe breakage:

1. Fatigue fracture
Fatigue fracture is one of the main causes of drill pipe fracture, because the drill pipe needs to continuously withstand large tensile, bending and torsion forces for a long time during drilling operations. These forces will cause changes and damage to the material properties of the drill pipe, and ultimately Cause the drill pipe to break.

2. Material defects

There may be material defects in the drill pipe during the manufacturing process, resulting in insufficient strength of the drill pipe during use, and accidents of drill pipe breakage may easily occur.

3.Excessive wear and tear
Drill pipe needs to excavate the well wall for a long time during drilling operations, which will cause excessive wear on the surface of the drill pipe and accelerate fatigue and fracture of the drill pipe.

4. Improper operation
During drilling operations, improper operation may cause the drill pipe to twist, side load and other abnormal conditions, which may further cause the drill pipe to break.

Preventive measures for drill pipe breakage:

1. Strengthen equipment maintenance
Conduct regular maintenance and inspections on equipment, and promptly replace seriously worn parts and drill pipes with material defects to reduce the occurrence of drill pipe fractures.

2. Strengthen personnel training
Strengthen the safety awareness of drilling operators and provide regular training on operating skills to avoid drill pipe breakage caused by improper operations.

3. Use high quality materials
High-quality materials should be selected to make drill pipes to reduce the occurrence of material defects and fatigue fractures.

4. Control drilling parameters
By controlling drilling parameters, excessive wear of the drill pipe is reduced and the service life of the drill pipe is ensured.

In short, strengthening safety production management in drilling operations, regularly inspecting equipment maintenance and strengthening personnel training, optimizing drilling parameter control, using high-quality materials and other measures can effectively reduce the occurrence of drill pipe fractures and ensure the safety and smooth progress of drilling operations.
