摘要： An apparatus (100) for controlling the flow rate of a fluid during downhole operations. The apparatus (100) includes a tubular member (134) having a flow path (136) between inner and outer portions of the tubular member (134). The flow path (136) includes an inlet (138) in an inner sidewall (140) and an outlet (142) in an outer sidewall (144) of the tubular member (134). The inlet (138) and the outlet (142) are laterally offset from each other. A fluidic device (146) is positioned in the flow path (136) between the inlet (138) and the outlet (142). The fluidic device (146) is embedded within the tubular member (134) between the inner sidewall (140) and the outer sidewall (144). The fluidic device (146) includes a nozzle (154) having a throat portion (156) and a diffuser portion (158) such that fluid will flow through the nozzle (154) at a critical flow rate.
