High-temperature and high-pressure hanging piece dynamic corrosion instrument

Abstract

The patent provides a high-temperature and high-pressure hanging piece dynamic corrosion instrument. The instrument comprises a stirring motor 1 and a drive mechanism connected with the stirring motor1, the drive mechanism includes stirring shaft 2, an outer magnet 3, an inner magnet 4, an outer magnet seat 5 and an inner magnet seat 6, the outer magnet 3 and the outer magnet seat 5 are fixedly connected, the inner magnet 4 and the inner magnet seat 6 are fixedly connected, the outer magnet 3 and the inner magnet 4 are in magnetic field coupling. The instrument can perform test for a petroleum drill rod made of steel prior to us to simulate the high-temperature and high-pressure environment in the pit and observe whether the alloy steel made of the material can be lower than the corrosionof deep underground media at the high temperature and the high pressure or not, and if the corrosion is caused, the instrument checks whether the damage caused by the corrosion affects the work of the drill rod or not. Therefore, qualified drill rod materials are obtained through testing, and the service life of the instrument is prolonged.

Description

technical field [0001] The invention relates to a petroleum scientific research instrument, in particular to a high-temperature and high-pressure coupon dynamic corrosion instrument. Background technique [0002] In the process of oil drilling in deep well drilling, the deep surface has high temperature and high pressure environment, and corrosive substances will corrode and rust the oil drill pipe. The produced oil drill pipe has not been tested and put into use. Finally, large-scale corrosion damage will be caused, which will affect mining production and cause serious consequences. Contents of the invention [0003] The present invention overcomes the deficiencies in the background technology and provides a high-temperature and high-pressure coupon dynamic corrosion instrument. The purpose of designing and developing this device: this device can test the oil drill pipe made of steel before use, and check the alloy steel made of this material Can it be lower than the cor...
