The commonly thickened rod has the following advantages:
1. High connection strength: The rough pier process increases the diameter of the two ends or specific connection parts of the drill rod, which significantly increases the contact area when connected to other drilling tools compared to ordinary drill rods. A larger contact area means a more uniform distribution of stress and the ability to withstand higher torque. When drilling complex formations, especially when strong twisting and pulling operations are required, it effectively reduces the risk of loose or fractured connection parts and ensures the continuity of drilling operations.
2. Good wear resistance: During the drilling process, the drill rod constantly rubs against the rock in the wellbore. Ordinary rough drill rods are often made of high-strength alloy steel material. After rough treatment, the surface hardness of the rod body is increased, making it more resistant to wear. Especially in highly abrasive rock layers, it can maintain its dimensional accuracy and integrity for a long time, reduce the time loss and cost increase caused by frequent replacement of drill rods, and extend the duration of a single operation.
3. Excellent stability: Due to the increased rigidity of the drill rod as a whole caused by the thick part of the pier, the drill rod is less likely to bend or deform during drilling. In deep drilling or large-diameter drilling construction, a stable drill rod can ensure that the drill bit moves along the predetermined trajectory, improve the verticality and straightness of the borehole, and the quality of the drilled wellbore is higher. Subsequent processes such as casing and cementing can also be carried out more smoothly.
4. Wide adaptability: Ordinary rough drilling rods come in various specifications and can be adapted to different models and sizes of drilling rigs and drill bits. Whether it is small civilian drilling equipment or large petroleum and geological exploration drilling rigs, matching rough drilling rods can be found to meet the needs of diverse construction scenarios. They have strong universality and can be flexibly applied in drilling projects in various fields.
5. Good cost-effectiveness: Although the initial procurement cost of rough drilling rods is slightly higher than that of some simple drilling rods, they have good durability and low risk of failure, reducing the number of shutdowns and repairs caused by drill rod damage. After long-term use, the overall cost investment of the drilling project is reduced, and the cost-effectiveness is highlighted.
