A method of manufacturing a fluidic oscillator insert for use in a subterranean well can include forming the insert with a conical housing engagement surface thereon, and forming at least one fluidic oscillator on a substantially planar surface of the insert. A well tool can include a housing assembly, at least one insert received in the housing assembly, the insert having a fluidic oscillator formed on a first surface thereof, the insert being at least partially secured in the housing assembly by engagement of conical second and third surfaces formed on the insert and housing assembly, and a cover which closes off the first surface on the insert. An insert for use in a well tool can include a conical housing engagement surface, and at least one fluidic oscillator formed on a substantially planar surface. The fluidic oscillator produces oscillations in response to fluid flow through the fluidic oscillator.

1. A method of manufacturing a fluidic oscillator insert for use in a subterranean well, the method comprising: forming the insert with a conical housing engagement surface thereon; andforming at least one fluidic oscillator on a substantially planar surface of the insert, wherein the fluidic oscillator comprises:a fluid input;first and second fluid outputs on opposite sides of a longitudinal axis of the fluidic oscillator, whereby a majority of fluid which flows through the fluidic oscillator exits the fluidic oscillator alternately via the first and second fluid outputs; andfirst and second fluid paths from the fluid input to the respective first and second fluid outputs, wherein the first and second fluid paths cross each other between the fluid input and the respective first and second fluid outputs, and wherein flow of the majority of fluid via the first fluid path draws fluid into the second fluid output. 2. The method of claim 1, wherein a side of the fluidic oscillator is closed off by engagement between the fluidic oscillator insert and a cover which engages the substantially planar surface. 3. The method of claim 2, wherein the cover sealingly engages the substantially planar surface. 4. The method of claim 2, wherein the cover also has the conical housing engagement surface formed thereon. 5. The method of claim 1, wherein the conical surface comprises an exterior surface of the fluidic oscillator insert. 6. A well tool, comprising: a housing assembly;at least one fluidic oscillator insert received in the housing assembly, the fluidic oscillator insert having a fluidic oscillator formed on a first surface thereof, and the fluidic oscillator insert being at least partially secured in the housing assembly by engagement of conical second and third surfaces formed on the fluidic oscillator insert and the housing assembly, respectively; anda cover which closes off the first surface on the fluidic oscillator insert, wherein the fluidic oscillator comprises:a fluid input;first and second fluid outputs on opposite sides of a longitudinal axis of the fluidic oscillator, whereby a majority of fluid which flows through the fluidic oscillator exits the fluidic oscillator alternately via the first and second fluid outputs; andfirst and second fluid paths from the fluid input to the respective first and second fluid outputs, wherein the first and second fluid paths cross each other between the fluid input and the respective first and second fluid outputs, and wherein flow of the majority of fluid via the first fluid path draws fluid into the second fluid output. 7. The well tool of claim 6, wherein the first surface is substantially planar. 8. The well tool of claim 6, wherein the conical second and third surfaces comprise respective exterior and interior surfaces of the fluidic oscillator insert and the housing assembly. 9. The well tool of claim 6, wherein the cover sealingly engages the first surface. 10. The well tool of claim 6, wherein the cover comprises at least a portion of the conical second surface. 11. A fluidic oscillator insert for use in a well tool, the insert comprising: a conical housing engagement surface;at least one fluidic oscillator formed on a substantially planar surface, wherein the fluidic oscillator produces oscillations in response to fluid flow through the fluidic oscillator, and wherein the fluidic oscillator comprises:a fluid input;first and second fluid outputs on opposite sides of a longitudinal axis of the fluidic oscillator, whereby a majority of fluid which flows through the fluidic oscillator exits the fluidic oscillator alternately via the first and second fluid outputs; andfirst and second fluid paths from the fluid input to the respective first and second fluid outputs, wherein the first and second fluid paths cross each other between the fluid input and the respective first and second fluid output, and wherein flow of the majority of fluid via the first fluid path draws fluid into the second fluid output. 12. The insert of claim 11, wherein a side of the fluidic oscillator is closed off by engagement between the fluidic oscillator insert and a cover which engages the substantially planar surface. 13. The insert of claim 12, wherein the cover sealingly engages the substantially planar surface. 14. The insert of claim 12, wherein the cover comprises at least a portion of the conical housing engagement surface. 15. The insert of claim 11, wherein the conical surface comprises an exterior surface of the fluidic oscillator insert.
