Mechanics Model of Rotation Axis in Directive Rotary Steerable Drilling System

Abstract:

The mechanics model was established on the basis of simplifying structure and supporting of rotation axis in directive rotary steerable drilling system. Rotation equation, deflection curve equation, reaction and moment equation of the rotation axis under the static offset condition were derived and the location of offset force F was optimized, which provide a basis for theoretical calculation on engineering design and structure optimization for directive rotary steerable drilling system.
