[0002] A hydraulic oscillator is a commonly used tool in the drilling industry. It is mainly used to generate mechanical vibration during the drilling process to reduce friction between the drill pipe and the well wall, prevent stuck drill bit, and improve drilling efficiency and safety. It utilizes fluid dynamics effects and a specially designed internal structure to generate pressure pulsations in the drilling fluid, which are then converted into mechanical vibrations.
