Abstract: Taking into account various factors that affect the trajectory change trend of the Push-the-bit automatic vertical drilling system during vertical well drilling, an experimental evaluation device for the trajectory control ability of the Push-the-bit automatic vertical drilling system was designed and developed. The functional implementation of the experimental evaluation device, the determination of the main structural components and key parameters of the device, and the simulation process of the influence law of wellbore drilling trends under different working conditions were introduced. The functional design and characteristics of the simulation process were also discussed. Through this experimental evaluation device, it is possible to understand the implementation process of trajectory control for the push-the-bit automatic vertical drilling system, the principle of changing wellbore trends, the impact of geological factors and drilling parameters on trajectory control effectiveness, and the comprehensive consideration of changes in the wellbore under various factors. Therefore, research and breakthroughs can be carried out on a new type of push-the-bit automatic vertical drilling system. This evaluation experimental device provides a platform for deepening the understanding and comprehension of automatic guidance technology, and supports the innovation and development of automatic vertical drilling systems.
