Dynamic Response and Safety Analysis of “Xuanji” Steering Tool

Shiyou jixie
The “Xuanji” steering tool uses three independent wing ribs which push against the borehole wall to generate bias force,so as to achieve effective control of wellbore trajectory and thus improve drilling efficiency.However,this design complicates the ...
