Based on the research results of existing vibratory cementing tools, this paper discusses the advantages and disadvantages of different vibratory cementing devices and proposes a design scheme for an assembled vibratory cementing tool. The scheme adopts a multi-section combination, which generates longitudinal and radial vibrations throughout the cementing process. Due to the special connection method, the tool has no obvious weaknesses and is suitable for various complex working conditions. In this paper, the efficiency and vibratory excitation force of the designed turbine-driven bidirectional vibratory cementing tool are numerically simulated. This simulation is utilized as an evaluation index to assess the operational performance of the vibratory cementing tool. Finally, the vibratory cementing tool is comprehensively optimized based on this analysis. The results of the study show that reducing the tray spacing, increasing the number of turbines, and using eccentrics have a positive effect on increasing vibratory force. The results lay the foundation for the design optimization of vibratory cementing tools.
