Abstract
A well tool can include a first oscillator which varies a flow rate of fluid, and a second oscillator which discharges the fluid received from the first oscillator at a variable frequency. A method can include flowing a fluid through a first oscillator, thereby repeatedly varying a flow rate of fluid discharged from the first oscillator, and receiving the fluid from the first oscillator into a second oscillator. A well tool can include a first oscillator including a vortex chamber, and a second oscillator which receives fluid flowed through the vortex chamber.
