Abstract
The invention relates to a non-magnetic pressure bearing drill stem with wear-resistant belts. The non-magnetic pressure bearing drill stem comprises a drill stem body. An internal thread connector for connecting an adjacent drill stem is arranged at one end of the drill stem body. An external thread connector for connecting an adjacent drill stem is arranged at the other end of the drill stem body. A first small-diameter section, a first thickened section, a second small-diameter section, a second thickened section and a third small-diameter section are sequentially arranged in the middle of the drill stem body from left to right. The first wear-resistant belt is arranged on the outer circumference of the internal thread connector. The second wear-resistant belt is arranged on the outer circumference of the external thread connector. The third wear-resistant belts are arranged on the outer circumferences of the first thickened section and the second thickened section respectively. By welding the wear-resistant belts to the connectors and the thickened sections of the non-magnetic pressure bearing drill stem, the pressure bearing drill stem is made to make contact with a well wall first in the use process, the contact pressure of a non-magnetic pressure bearing drill stem body and the well wall is reduced or the non-magnetic pressure bearing drill stem body does not make contact with the well wall, the wear speed of the non-magnetic pressure bearing drill stem body is effectively decreased, the service life of the drill stem is greatly prolonged, and the non-magnetic pressure bearing drill stem can be widely applied to the field of non-magnetic pressure bearing drill stems.
