AB - The fully rotary internal steering drilling tool is a key execution component of the rotary steering drilling system, which is a new type of dynamic directional downhole closed loop rotary steering drilling tool. The study was aimed to investigate the motion of fully rotary steering drilling tool. According to the corresponding spatial mechanism, the kinematics model of the fully rotary built-in steering drilling tool was established, and the kinematics analysis of the system was carried out. The validity of the model was verified by comparing with the simulation results of SolidWorks. The basic kinematic parameters of the key components, such as inner and outer eccentric annulus, angular velocity and displacement of drill are obtained theoretically, and the kinematic characteristics of the guiding mechanism are revealed. In this paper, the relationship between rotational speed, eccentricity and trajectory of drill was studied, and the variation of various parameters in the system with time is obtained, which provides a theoretical basis for well trajectory control of fully rotary built-in steel drilling tools.
