According to another embodiment, a device for directing the flow of a fluid comprises: a sensor; a first outlet connected to the sensor; a second outlet connected to the sensor; a first outlet fluid passageway; and a second outlet fluid passageway; wherein as the total number of phases of the fluid increases, the sensor directs at least a first phase of the fluid into the first outlet fluid passageway and directs at least a second phase of the fluid into the second outlet fluid passageway, and wherein the fluid flowing through the first outlet fluid passageway conjoins with the fluid flowing through the second outlet fluid passageway at a point downstream of the first and second outlet.
Abstract:
A device for vibrating tubing as it is inserted into a wellbore is disclosed. The device has a fluidic switch that has no moving parts. The fluidic switch is connected to a piston that oscillates back and forth in a cylinder. The piston is the only moving part. As the piston oscillates, it blocks and unblocks openings in the cylinder or other components. The movement of the piston controls the timing of the oscillation, and also generates an impulse or vibration. The vibration may reduce the friction between the tubing and the wellbore.

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.
Abstract:
A well tool can comprise a fluid input, a fluid output and a fluidic oscillator which produces oscillations in a fluid which flows from the input to the output. The fluidic oscillator can include a vortex chamber with inlets, whereby fluid enters the vortex chamber alternately via the inlets, the inlets being configured so that the fluid enters the vortex chamber in different directions via the respective inlets, and a fluid switch which directs the fluid alternately toward different flow paths in response to pressure differentials between feedback fluid paths. The feedback fluid paths may be connected to the vortex chamber. The flow paths may cross each other between the fluid switch and the outlet.

Abstract:
The invention relates to fluid actuator for influencing the flow along a flow surface through ejection of a fluid. By means of a like fluid actuator, a continuous flow is distributed to at least two outlet openings in order to generate fluid pulses out of these outlet openings. Control of this distribution takes place inside an interaction chamber which is supplied with fluid flow via a feed line. Into this interaction chamber there merge at least two control lines via control openings to which a respective different pressure may be applied. Depending on the pressure difference at the control openings, the flow in the interaction chamber is distributed to the individual outlet openings.
