During the use of petroleum drill pipes, various problems may be encountered. The following are some common problems and their solutions:
1. Piercing or breaking at the root of the male joint thread:
·Cause of occurrence: Insufficient torque on the buckle leads to fatigue cracks; The thread parameters or material strength of the joint are not qualified.
·Solution: Use high-strength and high toughness alloy steel as drill pipe material; Strictly control manufacturing processes and parameters; Avoid overload and overvoltage during homework; Regularly conduct ultrasonic testing on drill pipes to promptly identify and address potential issues.
2. Stuck drill problem:
·Cause: Complex geological formations, improper operation, etc. caused the drill pipe to get stuck.
·Solution: Use methods such as impact method, rotation method, hydraulic flushing method, drilling tool extraction method, or auxiliary tool method to remove stuck drilling. At the same time, improve drilling technology level and reduce stuck accidents caused by operational errors.
In addition to the specific issues mentioned above, the following points should also be noted:
1. Reasonable material selection and processing technology: High strength and high toughness alloy steel is used as the main material, and the manufacturing process is strictly controlled to ensure stable quality of drill pipes.
2. Use and maintenance of drill pipes: strictly follow the prescribed operating parameters and procedures; Regularly clean, inspect, and maintain drill pipes; Replace severely worn components in a timely manner.
3. Improvement of drilling technology: Adopting advanced drilling technology and equipment, such as adaptive control systems, real-time monitoring, and remote control systems, to improve drilling efficiency and safety.
In summary, common problems in the use of petroleum drill pipes involve multiple aspects, and effective solutions need to be developed by considering multiple factors such as materials, processes, operations, and maintenance.
