FLUIDIC OSCILLATOR BYPASS SYSTEM

摘要

A fluidic oscillator assembly can include at least one fluidic oscillator, and a closure that in one position prevents flow through the oscillator to an exterior of the assembly, and in another position permits flow through the oscillator to the exterior. A method can include flowing fluid longitudinally through a fluidic oscillator assembly in a well, then diverting the fluid to flow outward from the assembly via at least one fluidic oscillator, the fluid being prevented from flowing longitudinally through the assembly. A well system can include a drill string having a fluidic oscillator assembly, a drill bit, and a drilling motor disposed between the drill bit and the assembly. The assembly can include a closure that in one position prevents fluid flow through a fluidic oscillator to an annulus formed between the drill string and a wellbore, and in another position permits fluid flow through the oscillator.
