In oil drilling operations, hoses are a crucial component used to transport liquids such as mud, cement, chemicals, etc. The failure of the hose may cause interruption of drilling operations and even lead to safety accidents. Therefore, timely fault diagnosis and effective repair are important measures to ensure the continuity and safety of drilling operations. This article will explore the fault diagnosis and repair methods of oil drilling hoses, as well as how to improve the efficiency and reliability of drilling operations through these measures.

1、 Fault diagnosis

Visual inspection

Conduct a thorough visual inspection of the hose to identify external damage such as cuts, cracks, bulges, or wear.

Check if there is corrosion, leakage, or deformation in the hose joints and connecting parts, which may be caused by incorrect installation or excessive tightening.

Stress testing

Perform a pressure test on the suspected problematic hose to check if its internal structure is intact.

Use professional testing equipment, such as hydraulic or pneumatic testing equipment, to determine whether the hose can withstand the specified working pressure.

Non destructive testing

Apply X-ray, ultrasonic, or other non-destructive testing techniques to detect internal defects in hoses, such as internal wear, rupture, or delamination.

These technologies can provide detailed images of the internal structure of hoses, helping maintenance personnel accurately identify the location and nature of faults.

2、 Repair method

Temporary repair

For small cracks or perforations, specialized repair straps or sleeves can be used for temporary repair to quickly restore the function of the hose.

These repair materials usually have high chemical resistance and wear resistance, and can withstand the conditions of drilling operations in a short period of time.

Permanent repair

For severe damage, such as deep cracks or extensive wear, permanent repair may be required, which may include replacing damaged hose segments or the entire hose.

When repairing, make sure to use materials that match the original hose material and have professional personnel perform the operation to ensure that the repaired hose meets safety standards.

Preventive maintenance

After repairing the hose, implement preventive maintenance measures such as regular inspections, proper storage, and operational training to reduce the occurrence of future failures.

These measures help to extend the service life of hoses and prevent similar failures from happening again.

3、 Improve the continuity of drilling operations

On site spare hose

Maintain a certain number of spare hoses and critical components for quick replacement in case of failure, reducing downtime.

These spare hoses should be regularly inspected and maintained to ensure they are always available.

Maintenance and training plan

Develop a comprehensive maintenance plan, including regular hose inspections, cleaning, and protective measures, as well as continuous training for operators.

Ensure that all personnel involved in hose operation and maintenance are aware of best practices and safety procedures.

Fault analysis and improvement

Conduct a detailed analysis of each hose failure to determine the cause and improvement measures.

Based on the results of fault analysis, adjust the operation and maintenance procedures to improve the reliability of hoses and the overall efficiency of drilling operations.

conclusion

The fault diagnosis and repair of oil drilling hoses is an indispensable part of drilling operations. By adopting appropriate diagnostic techniques and repair methods, hose problems can be quickly and effectively solved, downtime can be reduced, and the safety and continuity of drilling operations can be improved. Meanwhile, by implementing preventive maintenance, on-site backup hose management, and maintenance training programs, the reliability of hoses can be further improved to ensure the smooth progress of drilling operations. These measures not only help extend the service life of hoses, but also help reduce the cost and risk of drilling operations.
