Definitions
- the field of this invention relates to alternate paths for gravel during downhole gravel packing operations and more particularly to spirally shaped paths in the form of a surrounding hollow auger for a gravel pack screen assembly. Spirally wrapped shunt tubes are further contemplated.
- a common problem when gravel packing is that the gravel forms bridges and leaves gaping areas uncovered as the gravel that is subsequently delivered piles up behind the bridge or blockage.
- Another problem is the difficulty in delivering screen into long horizontal runs because of the limited weight available to advance the screen and the possibility that it may simply buckle in the wellbore and cease to further advance.
- Yet another issue is the need to centralize the screen as the gravel is delivered for deposition all around it.
- Another concern is damage to the screen assembly during run in. Gravel screens have been provided in the past with surrounding shrouds but the delivery to the desired location could still cause damage to the shroud and the underlying screen.
- Bridge formation is always a concern. Annular bridge formation can be aggravated by zones of low flow rates leading to deposition of undue amounts of gravel in concentrations in undesirable locations leading to a bridge ultimately forming.
- the present invention addresses in a cohesive design several parameters.
- The_holLowjfligh Qr_flights.oiLaugers are structurallyjrigid. to llow_rotation-to-advance- the screen.
- the passages in the flights are also protected by the rigidity of the auger design.
- the screen is better protected during run in.
- the auger allows gravel to enter and exit in multiple locations to allow gravel to bypass bridges.
- the spiral flow pattern in the interior and along the exterior of the auger is more turbulent due to the centrifugal force from going around the screen, making it less likely that gravel will deposit within the auger or prematurely in the annulus.
- the auger centralizes prior to gravel delivery.
- a gravel pack screen assembly has one or more hollow flight augers that a continuous or segmented with multiple upwardly oriented gravel entrances and multiple downwardly oriented gravel exits.
- the gravel passes through the auger and around any bridge.
- the auger helps advance the screen into position as well as to centralize it during gravel deposition.
- the auger protects the screen during run in as well as the internal passages that pass through it due to its structural rigidity.
- An alternative embodiment features spirally wound tubes with staggered exit locations for better distribution of the gravel.
- Figure 1 is an exterior view of a screen assembly with a single flight hollow auger mounted to it showing the flow of gravel through the hollow flight;
- Figure 2 is a section view of an alternative embodiment showing the spirally wrapped-tubesj-
- Figure 3 is the view along lines 3-3 of Figure 2;
- Figure 4 shows an outer view of the jacket mounted over joints in the screen assembly
- Figure 5 is the view along lines 5-5 of Figure 4.
- the screen assembly 10 can be made up of multiple sections such as 12 and 14 that are connected by a coupling 16.
- the actual screen, shown by dashed line 18 is below an outer protective jacket 20.
- the protective jacket 20 stops short of each coupling 16 so that the proper length of the assembly 10 can be put together for a given application.
- the auger 22 is hollow and has an inlet 24 near the top where gravel, represented by arrow 26 can enter. There is a plurality of exits 28 on the auger underside for the gravel 26 to exit.
- the auger 22 may be made continuous over the couplings 16 such as by installing the segments that pass the coupling 16 after it is assembled.
- the auger 22 can stop before some or all of the couplings 16 and resume on the protective jacket 20 immediately below the coupling 16. In this manner there can be multiple inlets 24 where each section of auger 22 begins. Additionally or alternatively, there can be additional inlets on the uphole side 30 of auger 22 for the purpose of letting in gravel 26 at multiple points along a length of continuous auger 22.
- the pitch and/or diameter of auger 22 can be constant or variable. There can be a single auger 22 or nested augers. Auger 22 may be made of the same metallic material as the protective jacket 20 and attached by a variety of techniques, although welding is preferred. Alternatively the auger 22 can be non-metallic as can be the protective jacket 20. They can be made integrally or the auger 22 can be mounted separately to jacket 20.
- the inlets 24 and outlets 28 can have a variety of shapes and sizes guided by the need to maintain the structural integrity of the auger 22 during conditions of its rotation to advance the screen assembly 10 into position before the gravel 26 is " dep ⁇ sifed rha ⁇ known mannerT ⁇ IT ⁇ f lessThan all ⁇ f m ⁇ lehguTof the screen assemblyTCT can be covered with the hollow auger 22.
- Periodically, short cut passages 32 can extend longitudinally from the underside of auger 22 to the uphole side 30 immediately below as yet another path for the gravel 26 to take if auger 22 starts to plug internally.
- auger 22 creates turbulence around the screen assembly 10 so as to make it less likely in the first place that sand bridges will form.
- the presence of the hollow auger 22 allows the gravel alternate paths to enter at the start or along the way on each auger or segment thereof and to exit on the downhole side of the auger or its segments anywhere along the length where an outlet is provided and at all lower open ends of hollow auger 22.
- the auger 22 acts as a centralizer on the trip downhole. It also protects the screen assembly 10 from mechanical damage during run in. The auger 22 also helps to advance the screen assembly into proper position. This can be useful in a nearly horizontal run where the ability to push the screen assembly 10 forward without buckling it may be severely limited.
- This problem can occur in regions of shale instability where contact by water based fluids makes the shale unconsolidated so that it can collapse into the wellbore. If this happens the alternate paths through the auger 22 allow gravel to also bypass the region of shale collapse.
- the auger 22 can be assembled to the protective jacket 20 such as by welding and then the assembly can be rolled over the screen material and secured to the base pipe underlying the screen material. Removal of the screen assembly 10, should that become necessary, is made easier by just applying an uphole force to the screen assembly 10. The auger 22 will put the screen assembly into rotation and the pitch of the auger 22 will drive the auger out of the gravel.
- the auger 22 in its various embodiments described above addresses several potential problems involved in running gravel pack screens.
- the alternate paths create internal turbulence and centrifugal force that helps to minimize blockages internally in the flow paths.
- turbulence is also created by auger 22 to help fight sand bridging.
- FIG. 2 illustrates an alternative embodiment of the present invention.
- four shunt tubes 34, 36, 38, and 40 as best seen in the section view of Figure 5 are disposed on the outside of screen 30.
- the shunt tubes 34, 36, 38, and 40 are equally spaced and spirally wound on the same pitch over the length of the screen assembly.
- Mounted over each joint 32 is a jacket 42.
- at least one of the shunt tubes 34, 36, 38, and 40 has an exit 44 under jacket 42. It also has an entrance 46 under jacket 42.
- Flow coming downhole through tube 34 exits and goes in three directions represented by arrows 46, 48, and 50.
- Arrow 46 shows the gravel exiting above the jacket 42
- arrow 48 shows the gravel exiting below the jacket 42
- arrow 50 shows the gravel re-entering tube 34 under jacket 42.
- Jacket 42 provides a jumper path for each other tube such as tubes 36 and 40 shown in Figure 2.
- Jacket 42 can have a discrete path for an individual tube or it can provide a common manifold so that flow from a variety of tubes can mix within the jacket and exit a different tube from the tube that a particular flow entered the jacket 42.
- a different tube 38 is open for flow in three possible directions as indicated by arrows 54, 56, and 58.
- At least one tube such as 40 has open ends 60 and 62 to allow flow out from under open coupling 64. Flow can go out above coupling 64 as indicated by arrows 66 and out below, as indicated by arrows 68. Between joints such as 32 and 52 a single tube may have one or more couplings 64. Alternatively more than one tube can have one or more couplings 64 between typical joints such as 32 and 52. As another variation, more than one of tubes 34, 36, 38, and 40 can have open ends under the jacket 42. The jacket 42 can be made in pieces 70 and 72 and held together by one or more bolts 74.
- the spiral winding will increase the overall length of the shunt tubes 34, 36, 38, and 40 as the wrap around the screen 30 but the fluid velocity will be higher as the spiral flow path will aid distribution of the gravel as it emerges from any openings in the shunt tubes 34, 36, 38, and 40.
- the spiral pattern will also better protect the screen 30 on insertion and help to better center it when it reaches the desired location.
- the number of tubes can be varied as well as their initial spacing and pitch. The diameter of an individual tube can be varied along its length.
- each tube will have breaks over a " fo tKlDrth lengtH of the screen ' s " 30 with " no " or minimal zone overlap.
- jacket 42 can be eliminated in favor of a jumper tube at a joint such as 32 for those tubes that have no openings at that location while the tubes with openings can have a coupling such as 64 at a joint such as 32.
