摘要： In accordance with an illustrative embodiment of the present invention, a well perforation cleaning tool includes a fluidic oscillator that creates pressure changes which induce cyclical stresses in the damaged skins of the perforations and causes the skins to disintegrate in order to improve the productivity of the well. Cylindrical filter tubes having a plurality of sets of slots are adjustably mounted at the upper and lower ends of the tool to provide resistances which confine the pressure changes to the immediate vicinity of the perforated interval.
摘要翻译：根据本发明的说明性实施例，穿孔清洁工具包括流体振荡器，该流体振荡器产生压力变化，其引起穿孔损坏皮肤中的周期性应力并导致皮肤分解以提高孔的生产率。具有多组槽的圆柱形过滤管可调节地安装在工具的上端和下端，以提供将压力变化限制在穿孔间隔附近的电阻。

摘要： In accordance with an illutrative embodiment of the present invention, a fluidic oscillator includes a transverse vacuum port which extends between the diffuser legs a predetermined distance below the leading edge surface of the splitter. When flow is down one leg, a slight negative pressure condition is created in the port and transmitted thereby to the other leg, which causes switching of the flow to such other leg. The process then repeats in response to negative pressure in the one leg to cause switching of the flow back thereto. Fluid flow thus is switched back and forth between the legs at a resonant frequency, so that continuously fluctuating pressures are applied to the surrounding medium.
摘要翻译：根据本发明的阴谋实施例，流体振荡器包括横向真空端口，其在扩散器支腿之间在分离器的前缘表面之下预定距离处延伸。当流动下降一条腿时，在端口中产生轻微的负压条件并由此传送到另一条腿，这导致流向另一条腿的切换。然后，该过程响应于一条腿中的负压而重复，以使流回到其上。因此，流体流以共振频率在腿之间来回切换，使得连续波动的压力施加到周围的介质。

摘要： In accordance with illustrative embodiments of the present invention, a well perforation cleaning tool includes a fluidic oscillator that creates pressure pulsations which induce cyclical stresses in the walls of the perforations and causes damaged skins thereon to disintegrate in order to improve the productivity of the well. The output passages of one embodiment of the fluidic oscillator are connected to respective internal storage cavities and each cavity is communicated with the annulus by a pair of outlet passages. In other embodiments, relatively short length external cavities communicate with the output passages to provide means by which the pressure pulsations are conveyed to the well annulus. Cylindrical filter tubes having a plurality of sets of axially spaced slots are adjustably mounted at the upper and lower ends of the tool may, if desired, be used to provide resistances which substantially confine the pressure pulsations to the immediate vicinity of the tool body. Both tubing conveyed and coil tubing conveyed tools are disclosed.
