The r32 drill rod manufacturer takes you to understand the application principle of drill rod

The r32 drill rod manufacturer tells you that in deep wells, ultra-deep wells, highly deviated wells, extended-reach wells and horizontal wells, the drilling time of the body rib drill pipe is prolonged, and the lateral force of the drill string on the casing is increased.

The r32 drill rod manufacturer tells you that in deep wells, ultra-deep wells, highly deviated wells, extended-reach wells and horizontal wells, the drilling time of the body rib drill pipe is prolonged, and the lateral force of the drill string on the casing is increased. The problem of friction and wear of columns is becoming more and more prominent. The direct consequence of severe wear is the rapid wear of the drill string, leading to premature failure; casing wear will reduce the crush strength and internal pressure resistance of the casing string, resulting in collapse, deformation and leakage of the casing string, and in severe cases, all Well scrapped. It not only affects our mining work, but even threatens the life safety of the staff in serious cases. In response to this problem, our maintenance technicians thought of some solutions.

The manufacturer of r32 drill rod tells you that the application of drill rods is not limited to the coal mining industry. Now many industries will use body rib drill rods, and the damage to the body rib drill rod joints in many places is relatively serious. The friction problem between some supporting equipment joints of the drill pipe and the casing cannot be ignored.
The manufacturer of r32 drill rod tells you that it has conducted in-depth research on the mechanism of friction and wear between drill pipe and casing, a series of problems caused by it and its preventive measures. The research contents mainly include: In order to explore the mechanism of friction and wear between drill pipe The elemental method studies the distribution of contact pressure between the joint and casing under different loads, and establishes a mathematical model of the maximum contact pressure and wear. The manufacturer of r32 drill rod tells you that the analysis results well explain the principle of reducing casing wear with single and double-side weld-hardened bands on drill pipe joints, and provide a theoretical and technical basis for the process of weld-hardened bands on drill pipe joints. In-depth theoretical analysis and experimental research are carried out on the problem of thermal cracking of drill pipe joints, the mechanism and process of thermal cracking failure of drill pipe joints are clarified, and measures to reduce or prevent thermal cracking failures of joints are proposed.
