Drill collar structure

The invention relates to a drill collar structure which comprises a drill collar short section, a mounting groove is formed in the drill collar short section and extends from the outer side wall of the drill collar short section to the axis direction of the drill collar short section, and the depth of the mounting groove is smaller than the thickness of the drill collar short section. And a while-drilling transmitting transducer is mounted in the mounting groove through a flexible connection structure. The while-drilling transmitting transducer is mounted in the mounting groove of the drill collar short section, so that the problem that oil needs to be filled in the prior art is solved; in addition, the transmitting transducer while drilling is fixed in the mounting groove through the flexible connection structure, so that the transmitting transducer while drilling has a better anti-seismic effect, and the service life of the transmitting transducer while drilling is prolonged. 本发明涉及一种钻铤结构，包括钻铤短节，所述钻铤短节上开设有安装
