Problems solved by technology

[0003] In the prior art, the data measurement of the inner diameter of the oil drill pipe joint is generally carried out manually through the mutual cooperation of calipers, vernier calipers and steel rulers. After the personnel measure multiple joints, it is prone to fatigue measurement errors, so the measurement efficiency is low

Abstract

The invention discloses a petroleum drill pipe joint detection device and method and relates to the field of petroleum machinery. By means of the device and the method, data measurement can be performed on the petroleum drill pipe joint inner diameters rapidly and accurately, and the measurement efficiency is improved. The device comprises a hollow inner diameter detection rod and an inner diameter detection line. The inner diameter detection rod comprises an inner diameter detection section, and an inner diameter supporting rod is arranged on the inner diameter detection rod. The first end of the inner diameter supporting rod is in rotary connection with the first end of the inner diameter detection section through a rotation shaft, the axial direction of the rotation shaft is vertical to the inner diameter detection rod, and an elastic part for rotating the inner diameter supporting rod towards the radial direction of the inner diameter detection rod is arranged between the inner diameter supporting rod and the inner diameter detection rod. A winding portion is arranged at the second end of the inner diameter detection section. One end of the inner diameter detection line is fixedly connected with the other end of the inner diameter supporting rod, and the other end of the inner diameter detection line bypasses the winding portion to stretch into a hollow region of the inner diameter detection rod and extends to the outside of the inner diameter detection rod. The device is mainly used for detection of petroleum drill pipe joint relevant parameters.

Description

technical field [0001] The invention relates to the field of petroleum machinery, in particular to a detection device and method for petroleum drill pipe joints. Background technique [0002] Oil drill pipe is an important part in oil and gas exploration and exploitation. It is mainly used to transmit torque and transport drilling fluid. The drill pipe is connected end to end through drill pipe joints, and the joints are processed with internal and external threads. During the production process of the drill pipe joint or the installation process of the drill pipe joint, it is necessary to measure the inner diameter of the drill pipe joint to ensure the precision of the production and the fit of the installation. [0003] In the prior art, the data measurement of the inner diameter of the oil drill pipe joint is generally measured manually through the cooperation of calipers, vernier calipers and steel rulers. This inspection method requires high measurement skills for the m...
