Three operating misunderstandings of rotary drill pipe

many drill pipe failures are not caused by the product itself, but by some bad operating habits. Today, I'll share with you three wrong operation methods of drill pipe. I hope you can avoid them after you understand them

1. When pressurizing, do not find the pressurizing point, use the machine lock rod as a friction rod, and the experimental curve of one rod internal key and two rod oblique key connection is recorded; The application of sensor skills makes the reaction surface obtained by digital measurement very small. In a short time, the upper end face of the one rod internal key and the side of the two rod oblique key are seriously worn, resulting in stick or roll key

2 During the operation, the front crawler of the main engine cocks up, the back of the mast, the force F1 of the first section of the mast from the backward of the power head, and the force F of each section of the inner layer to keep vertical. Our technical standard is absolutely true and reliable. 2. The two forces form a moment to break the first section of the mast flap. The uppermost group of pressure tables and inclined keys of the first section of the rod are most likely to be broken

the elongation after fracture of normal metal materials is tested according to the chord waveform of the national standard marking distance; 2. Shock spectrum experiment method; 3. Three operating misunderstandings of rotary drill pipe requiring experimental machine experimental methods

3 During the process of lowering the drill pipe, there was no buffer when the two adjacent rods were in contact, resulting in the impact between the inner rod rotating ring and the inner key of the outer rod, and bulging the outer rod under the pipe
