This invention discloses a composite impact-driven drilling tool, belonging to the field of oil and gas drilling technology. Addressing the problems of poor tool adaptability and asynchronous impact and reversing in existing technologies, this invention proposes a quantitative design method based on the fluid-structure interaction coefficient. The tool's actuating valve assembly includes a coaxially nested inner sleeve and a reversing valve, controlling fluid flow direction through a distribution structure. This invention defines the coupling coefficient between the geometric parameters of the reversing valve and the hydrodynamic parameters. This coefficient is jointly determined by the circumferential impact torque, reversing rotation angle, drilling fluid discharge rate, nozzle pressure drop, and the equivalent hydraulic diameter of the reversing valve, and is controlled within a specific preset range. Through the above quantitative design, the inverse relationship between the reversing angle and the discharge rate is forcibly constrained, achieving efficient synchronization of impact and reversing across the entire discharge range, effectively solving the problems of "idling" or "jamming," and significantly improving rock-breaking efficiency.
