摘要： A system for use with a subterranean well can include a fluid oscillator which discharges pulsating fluid from a tubular string in a direction at least partially toward an end of the tubular string proximate a surface of the earth. A method can include discharging a fluid from the tubular string, thereby applying a reaction force to the tubular string, which reaction force biases the tubular string at least partially into the well. Another method can include discharging a pulsating fluid from a fluid oscillator in a direction at least partially toward an end of the tubular string, and drilling into an earth formation with a drill bit connected at an opposite end of the tubular string in the well.

摘要： A fluidic oscillator can include a fluid switch, at least two fluid paths from the fluid switch, and a sensor which measures a frequency of fluctuations in flow through the fluidic oscillator. A method of measuring a flow rate of a fluid can include flowing the fluid through a fluidic oscillator, a majority of the fluid flowing alternately via at least two fluid paths from a fluid switch of the fluidic oscillator, and a sensor detecting a frequency of the flow alternating between the fluid paths. Another fluidic oscillator can include a fluid input, at least two fluid paths from the fluid input to respective fluid outputs, whereby a majority of fluid which flows through the fluidic oscillator flows alternately via the fluid paths, and a sensor which detects pressure fluctuations due to the flow alternating between the fluid paths.

摘要： A heated fluid injection string (106) injects heated treatment fluid into a well (102) in a subterranean zone (112) and generates an acoustic signal. An acoustic detector (212) detects the acoustic signal, and an acoustic signal analyzer (214) interprets the detected acoustic signal. In some implementations, the acoustic signal analyzer (214) interprets the detected acoustic signal to determine information about at least one of the heated fluid injection string (106), the well (102), or the subterranean zone (112).
