Definitions
- This disclosure relates generally to equipment utilized and operations performed in conjunction with a subterranean well and, in one example described below, more particularly provides a bypass system and method for use with a fluidic oscillator downhole.
- a fluidic oscillator can produce oscillations in fluid flow using fluidic elements, such as a fluidic switch, vortex chamber, etc.
- fluidic elements such as a fluidic switch, vortex chamber, etc.
- Such fluid flow oscillations can be used for treating or cleaning a sand control screen or gravel pack, for removing scale from casing, for treating subterranean earth formations, for example, to place matrix treatments, to acidize, etc. Therefore, it will be used for treating or cleaning a sand control screen or gravel pack, for removing scale from casing, for treating subterranean earth formations, for example, to place matrix treatments, to acidize, etc. Therefore, it will be
- FIG. 1 is a representative partially cross-sectional view of a well system and associated method which can embody principles of this disclosure.
- FIG. 2 is a representative cross-sectional view of a fluidic oscillator assembly that can be used in the system and method of FIG. 1, and which can embody principles of this disclosure.
- FIG. 3 is a representative perspective view of a structure of the assembly, the structure having fluidic oscillators formed therein.
- FIG. 4 is a representative cross-sectional view of the fluidic oscillator assembly of FIG. 2, with a closure thereof displaced to a oscillator output position.
- FIG. 1 Representatively illustrated in FIG. 1 is a system 10 for use with a well, and an associated method, which can embody principles of this disclosure.
- system 10 and method are merely one example of an application of the principles of this disclosure in practice, and a wide variety of other examples are possible. Therefore, the scope of this disclosure is not limited at all to the details of the system 10 and method described herein and/or depicted in the drawings.
- a drill string 12 is positioned in a wellbore 14.
- a portion of the wellbore 14 is lined with casing 16 and cement 18, and another portion of the wellbore is uncased or open hole. It should be clearly understood, however, that it is not necessary for any portion of the wellbore 14 to be uncased, and the method described herein can be practiced in any cased or uncased portion of the wellbore .
- the wellbore 14 is depicted in FIG. 1 as being
- the wellbore 14 (or any particular portion thereof) could be horizontal, inclined or otherwise oriented.
- the scope of this disclosure is not limited to performance of the method in a wellbore having any particular orientation.
- the FIG. 1 drill string 12 has connected therein a fluidic oscillator assembly 20 , a drilling motor 22 and a drill bit 24 .
- the fluidic oscillator assembly 20 is used to selectively transmit fluid flow oscillations 26 into an earth formation 28 penetrated by the wellbore 14 .
- the oscillations 26 may have any desired amplitude and
- the oscillations 26 enhance delivery of any type of treatment into the formation 28 .
- resins or other types of sand control treatments can be flowed into the formation 28
- permeability modifiers, aromatics or acids for stimulation can be flowed into the formation, etc.
- the scope of this disclosure is not limited to flow of any particular type of treatment fluid into the formation 28 .
- the drilling motor 22 is used to rotate the drill bit 24 .
- the drilling motor 22 could be a Moineau- type positive displacement motor, or a turbine drilling motor. Fluid flow through the drilling motor 22 causes rotation of the drill bit 24 , although the drill bit could also be rotated by rotating the drill string 12 at the earth's surface (for example, using a rotary table or a top drive ) .
- the drill bit 24 is used to drill through a plug 30 previously set in the casing 16 .
- the plug 30 could be set in an open hole portion of the wellbore 14 .
- the plug 30 could be set for well control or other purposes.
- the plug 30 is made of a relatively easily drillable material but, if harder materials are used in the plug, a mill could be used in place of the drill bit 24 .
- the term "drill bit” is used to indicate a cutting tool (including, but not limited to, drills, mills, reamers , etc . ) .
- fluid 32 flowed longitudinally through the drill string 12 should flow through the drilling motor 22 , in order to rotate the drill bit. If the fluid 32 were to flow outward from ports 34 in the assembly 20 , and into an annulus 36 external to the assembly, this would reduce the amount of fluid flowing through the drilling motor 22 , and thereby reduce an efficiency and speed of the drilling.
- the assembly 20 is to be used to produce the oscillations 26 while the fluid 32 is flowed into the formation 28 , it is desired for the fluid to flow
- the fluid 32 could be a drilling fluid (also know as drilling "mud” to those skilled in the art) while the drill bit 24 is being rotated with the drilling motor 22, and the fluid could be a treatment fluid while the assembly 20 produces the oscillations 26 in the flow of the fluid into the formation 28.
- drilling fluid also know as drilling "mud” to those skilled in the art
- treatment fluid while the assembly 20 produces the oscillations 26 in the flow of the fluid into the formation 28.
- FIG. 2 is an enlarged scale representative cross- sectional view of one example of the fluidic oscillator assembly 20 that can be used in the system 10 and method of FIG. 1.
- the assembly 20 can be used in other systems and methods in keeping with the principles of this disclosure .
- the assembly 20 includes a generally tubular housing 38 having the ports 34 formed therein for communication with the annulus 36 (see FIG. 1).
- Upper and lower connectors 40, 42 provide for connecting the assembly 20 in the drill string 12.
- the assembly 20 could, for example, be connected in a completion string, in a
- a closure 44 in the form of a sleeve.
- the closure 44 is releasably secured against displacement by a shear screw 46.
- Other types of releasable locks or latches such as, snap rings, collets, shear rings, shear pins, dogs, etc. may be used in place of, or in addition to, the shear screw 46, if desired.
- a passage 48 extends longitudinally through the closure 44 and longitudinally through the assembly 20. In the FIG. 2 position of the closure 44 , fluid flow completely longitudinally through the assembly 20 is permitted.
- the drilling motor 22 can be used to rotate the drill bit 24 with the assembly 20 in the FIG. 2 configuration.
- Seals 50 carried on the closure 44 are sealingly engaged in a seal bore 52 formed in the upper connector 40 , and in a seal bore 54 formed in a generally tubular
- the annular flow path 56 is in communication with an upper end of the structure 58 .
- Fluidic oscillators 62 are formed in an outer surface 60 of the structure 58 , and the fluidic oscillators are in communication with the ports 34 .
- the annular flow path 56 is placed in communication with the passage 48 , then the fluid 32 will be permitted to flow through the fluidic oscillators 62 to the openings 34 and thence outward into the annulus 36 (see FIG. 1 ) .
- FIG. 3 is an enlarged scale representative perspective view of an example of the structure 58 of the assembly 20 , the structure having the fluidic oscillators 62 formed therein. Two fluidic oscillators 62 are formed in the structure 58 , but in other examples any number of
- oscillators may be used.
- the fluidic oscillators 62 of FIG. 3 are similar in form and operation to those described in U.S. Publication No. 2012 / 0168013 .
- the fluid 32 can flow from the annular flow path 56 (see FIG. 2 ) into inlets outlets 66 .
- the outlets 66 are in communication with the ports 34 in the housing 38 (see FIG. 2 ) .
- oscillators 62 depicted in FIG. 3 are similar to those described in U.S. Publication No.
- the outer surface 60 of the structure 58 is frusto-conical shaped for
- the oscillations produced by the oscillators 62 are used after the plug 30 is drilled through, in order to deliver a treatment fluid to the formation 28 (e.g., for well control purposes).
- the oscillations may not be used after a drilling operation, and may not be used for delivering a treatment fluid into a formation, but could instead be used for cleaning or
- FIG. 4 is a representative cross-sectional view of the fluidic oscillator assembly 20 of FIG. 2 , with the closure 44 thereof displaced to an oscillator output (non-bypassed) position. In this position, the fluid 32 can flow into the annular flow path 56 and then through the fluidic
- a plug 70 (such as, a ball, dart etc.) is disposed in the passage 48 and sealingly engaged with a seat 72 in the closure.
- the plug 70 could be dropped into the drill string 12 at the surface, released from a downhole receptacle, or otherwise introduced into the passage 48.
- a predetermined pressure differential is then created across the plug 70.
- the upper connector 40 and an upper end of the closure 44 can be dimensioned so that the plug 70 will not displace into the annular flow path 56.
- the assembly 20 is substantially horizontal or inclined, and the pressure differential is not constantly maintained across the plug 70, it is possible that the plug could displace out of the passage 48.
- the plug 70 will displace with the flow, and will again sealingly engage the seat 72, without falling into the annular flow path 56.
- flow through the fluidic oscillators 62 can be delayed until use of the drilling motor 22 is no longer needed, at which point flow to the drilling motor can be diverted to the fluidic oscillators. In this manner, both of the drilling operation and the formation treatment operation can be accomplished with only one trip of the drill string 12 into the wellbore 14.
- the assembly 20 can comprise at least one fluidic oscillator 62 formed in a structure 58, and a closure 44 that in a first position prevents fluid flow through the fluidic oscillator 62 to an exterior of the assembly 20, and in a second position permits fluid flow through the fluidic oscillator 62 to the exterior of the assembly 20.

- the predetermined pressure differential across the plug 70 can displace the closure 44 from the first position to the second position.
- fluid flow may pass through the fluidic oscillator 62 between the structure 58 and an outer generally tubular housing 38 in which the structure is received.
- the method can comprise: flowing fluid 32 longitudinally through a fluidic oscillator
- the diverting step can comprise installing a plug 70 in a longitudinal passage 48 of the fluidic oscillator assembly 20.
- the diverting step can further comprise applying a predetermined pressure differential across the plug 70, thereby displacing a closure 44 from a first position in which the closure prevents flow of the fluid 32 through the fluidic oscillator 62 to a second position in which flow of the fluid 32 through the fluidic oscillator 62 is permitted.
- the passage 48 may be formed through the closure 44, and the closure 44 may be sealingly and slidingly received in a structure 58, with the fluidic oscillator 62 being formed in the structure 58.

- the diverting step can comprise preventing flow of the fluid 32 through the drilling motor 22.
- the diverting step may include the fluidic oscillator 62 producing oscillations 26 in the fluid flow, the fluid flow oscillations being communicated into the earth
