The invention relates to the technical field of ultrasonic thickness measuring equipment, and discloses an electromagnetic ultrasonic thickness measuring device for a drill rod, which comprises bearing tables arranged in pairs, and rotating mechanisms for driving the drill rod to rotate are arranged on the bearing tables; the detection trolley is used for detecting the thickness of the drill rod, the driving mechanism comprises pulleys attached to the surface of the drill rod, and the pulleys are provided with oblique threads, so that when the drill rod rotates, the detection trolley can walk along the surface of the drill rod. The electromagnetic ultrasonic thickness measuring device for the drill rod is simple in overall structure, can be suitable for high-speed, automatic and non-contact thickness measurement work of the whole pipe body of the drill rod with different wall thicknesses, is high in overall testing precision, is easy to adapt to the drill rod, can achieve rapid detection and taking and placing work of the drill rod, starts from in-place drill rod detection in a severe environment, and is high in practicability. The occupied area is small, and carrying is convenient.
Description
technical field [0001] The invention relates to the technical field of ultrasonic thickness-measuring equipment, in particular to an electromagnetic-ultrasonic thickness-measuring device and a thickness-measuring method for drill pipes. Background technique [0002] As one of the most commonly used tools in deep oil and gas well exploitation, the quality of drill pipe is of great significance to the safe and efficient operation of oil and gas exploitation. However, when the drill pipe is working online, the stress is complicated. There is strong friction between the outer wall of the drill pipe and the well wall or casing, and the inside of the drill pipe is eroded and corroded by high-speed and high-pressure drilling fluid. Fatigue corrosion occurs, resulting in thinning of the wall thickness. In particular, the thinning of the wall thickness of the thickened transition zone will cause the pipe body to puncture or rupture, causing safety accidents. Therefore, it is of grea...
