Definitions
- ICD Inflow control devices
- ICDs can be placed in the completion string to reduce production from high producing zones, and thus stimulate production from low or non-producing zones.
- flow control devices can be used to supply a more uniform flow of injection fluid or specified different flows of fluid to different zones of the formation. There are yet other applications of flow control devices.
- the concepts described herein encompass a well screen assembly including a tubular base pipe.
- the base pipe has a sidewall aperture that communicates fluid between an interior central bore of the base pipe and an exterior of the base pipe.
- a filtration screen is around the base pipe.
- the filtration screen defines a lateral fluid passage along a axial length of the well screen assembly.
- a flow control device is coupled to the base pipe and the filtration screen.
- the flow control devices includes a ring sealing the lateral fluid passage from the central bore.
- An elongate restrictor passage is in the ring, oriented longitudinally.
- the elongate restrictor passage is configured to communicate fluid between the lateral fluid passage and the central bore.
- the restrictor passage includes an internal, square edged orifice defined by a fixed, annular protrusion.
- the annular protrusion extends inwardly from an interior surface of the restrictor passage.
- the concepts herein encompass a well device including a tubing having a sidewall aperture through to the central bore of the tubing.
- a flow control housing is carried on the tubing and defines an annular chamber over the aperture.
- a flow control ring seals a first portion of the annular chamber in fluid communication with the aperture from a second portion of the annular chamber.
- An orifice tube extends longitudinally through the flow control ring, and communicates the first and second portions of the annular chamber.
- the orifice tube includes an internal, square edged orifice defined by a fixed, annular protrusion extending inwardly from an interior surface of the orifice tube.
- the concepts herein encompass a method of controlling flow in a well.
- flow between an interior central bore of a tubular base pipe and a filtration screen about the base pipe is received in a flow control device.
- the flow is restricted by an elongate restrictor passage oriented longitudinally.
- the restrictor passage comprises an internal, square edged orifice defined by a fixed, annular protrusion extending inwardly from an interior surface of the restrictor passage.
- FIG. 1 is a side cross-sectional view of an example well system including a plurality of well screen assemblies.
- FIG. 2 is a side cross-sectional view of an example well screen assembly with a flow control device.
- FIG. 3 is an axial cross-sectional view of the example well screen assembly of FIG. 2 taken along 3-3.
- FIG. 4 is a side cross-sectional view of a restrictor tube.
- FIG. 1 illustrates an example well system 10 including a plurality of well screen assemblies 12.
- the well system 10 is shown as being a horizontal well, having a wellbore 14 that deviates to horizontal or substantially horizontal in the subterranean zone of interest 24.
- a casing 16 is cemented in the vertical portion of the wellbore and coupled to a wellhead 18 at the surface 20.
- the remainder of the wellbore 14 is completed open hole (i.e., without casing).
- a production string 22 extends from wellhead 18, through the wellbore 14 and into the subterranean zone of interest 24.
- a production packer 26 seals the annulus between the production string 22 and the casing 16. Additional packers 26 can be provided between the screen assemblies 12.
- the production string 22 operates in producing fluids (e.g., oil, gas, and/or other fluids) from the subterranean zone 24 to the surface 20.
- the production string 22 includes one or more well screen assemblies 12 (three shown).
- the annulus between the production string 22 and the open hole portion of the wellbore 14 may be packed with gravel and/or sand.
- the well screen assemblies 12 and gravel/sand packing allow communication of fluids between the production string 22 and subterranean zone 24.
- the gravel/sand packing provides a first stage of filtration against passage of particulate and larger fragments of the formation to the production string 22.
- the well screen assemblies 12 provide a second stage of filtration, and are configured to filter against passage of particulate of a specified size and larger into the production string 22.
- the concepts herein can be applied to other well configurations, including vertical well systems consisting of a vertical or substantial vertical wellbore, multi-lateral well systems having multiple wellbores deviating from a common wellbore and/or other well systems.
- concepts herein can are applicable in other contexts, including injection (e.g., with the well screen assembly 12 as part of an injection string), well treatment (e.g., with the well screen assembly 12 as part of a treatment string) and/or other applications.
- the example well screen assembly 12 includes an apertured base pipe 100 (with square, round, slotted and/or other shaped apertures 102 in the sidewall) that carries a filtration screen assembly 104.
- the ends of the base pipe 100 are configured to couple (e.g., threadingly and/or otherwise) to other components of the completion string.
- the apertures communicate fluid between an interior central bore 106 of the base pipe 100 and an exterior of the base pipe.
- a flow control device 110 is positioned circumferentially about the base pipe 100.
- the filtration screen assembly 104 is positioned circumferentially about intermediate portion of the base pipe 100, sealed at one end to the base pipe 100 and sealed to the flow control device 110 at its other end.
- the flow control device 110 operates as a flow restriction of specified characteristics to control the flow between central bore 106 and the exterior of the well screen assembly 12 and surrounding well bore annulus and subterranean zone.
- one or more other flow control devices 110 can be positioned on the base pipe 100, for example, at the opposing end of the screen assembly 104 and/or intermediate the ends of the screen assembly 104.
- the screen assembly 104 is sealed at both ends to a flow control device 110.
- the screen assembly 104 is a filter that filters against passage of particulate of a specified size larger.
- Screen assembly 104 can take a number of different forms and can have one or multiple layers. Some example layers include a preformed woven and/or nonwoven mesh, wire wrapped screen (e.g., a continuous helically wrapped wire), apertured tubing, and/or other types of layers.
- Screen assembly 104 defines lateral fluid passages 108 interior to the screen assembly 104 and/or between the screen assembly 104 and the base pipe 100. The lateral fluid passages 108 communicate fluid axially along the length of the flow control device 110.
- the flow control device 110 includes an outer housing 112 affixed and sealed to the base pipe 100 at one end and affixed and sealed to the screen assembly 104 at the opposing end.
- the housing 112 defines an annular chamber 114 in communication with the lateral passages 108 of the screen assembly 104 and the central bore 106 via the apertures 102.
- the housing 112 has a flow restrictor ring 116 between the apertures 102 and the screen assembly 104.
- the flow restrictor ring 116 is sealed to the exterior of the base pipe 100, for example, by welding, by mechanical seals, and/or in another manner, to seal the apertures 102 from the lateral passages 108 of the screen assembly 104.
- All flow between the apertures 102 and the lateral fluid passages 108 must flow through a plurality of elongate restrictor tubes 118 carried by the flow restrictor ring 116.
- the flow restrictor ring 116 can be a separate piece that is also sealed to the interior of the housing 112.
- the restrictor tubes 118 have a plurality of internal flow orifices 122 configured to cause a specified flow rate drop and/or pressure drop in flow through the tubes.
- the plurality of orifices 122 provide a multistage flow restriction.
- the restrictor tubes 118 are affixed in the restrictor ring 116, for example, removably with threads on the exterior of the restrictor tubes 118 that mate with corresponding threads in a bore 120 in the restrictor ring 116.
- the restrictor tubes can be clamped between mating components of the restrictor ring 116, bonded (e.g., by welding, brazing, adhesive, and/or other bond) and/or otherwise removably or permanently attached. As seen in FIG.
- the flow path through the restrictor tubes 118 is straight and oriented longitudinally in the housing 112, parallel (precisely or substantially parallel) to the longitudinal axis of the base pipe 100.
- the tubes 1 18 are straight, they are also oriented longitudinally in the housing 112.
- Other orientations are within the concepts described herein.
- One end of the restrictor tubes 118 is near the filtration screen assembly 104 and the other is near the apertures 102. In the configuration of FIG. 2, there is nothing between the end of the restrictor tubes 118 and the outlet of the lateral passages 108, nor is there anything between the end of the restrictor tubes 118 and the apertures 102.
- the restrictor tubes 118 are the primary restriction to flow through the flow control device 110.
- FIG. 3 shows the restrictor tubes 118 being equally azimuthally spaced apart (i.e., the azimuth between each restrictor tube 118 is equal), but in other instances, they can be otherwise irregularly or regularly spaced.
- the restrictor tubes 118 each have one or more internal square edged, orifices 122 configured to cause a specified drop in flow rate through the tubes.
- Each orifice 122 is defined by a fixed, annular protrusion protruding inwardly from an interior surface of the restrictor tube 118.
- the flow area through the orifices 122 is the most restrictive flow area through the restrictor tube 118, and in certain instances, through the entire flow control device 110.
- the remainder of the restrictor tube 118 is of a
- the restrictor tubes 118 are shown as cylindrical (i.e., with a round inner cross-section), so in the provided example, the largest transverse dimension is the inner diameter. However, in other instances, the tubes 118 can be other shapes.
- the orifices 122 are configured to provide a flow rate drop that has a greater independence to fluid viscosity than other common flow restriction shapes.
- orifice 122 is square edged in that at least one of the orifice's openings 124, and in FIG. 2 both its opening 124 toward the filtration screen assembly 104 and its opening 124 toward the apertures 102, have edges defined by surfaces meeting at right angles (precisely or substantially right angles). In certain instances, one or both of the edges can be provided without a fillet or chamfer added to the edge and can even be manufactured to be sharp.
- the annular protrusion that defines the orifice 122 can have a square shoulder 126 (FIG.
- the shoulder 126 is orthogonal (precisely or substantially orthogonal) to the longitudinal axis of the restrictor tube 118.
- FIG. 2 shows the square shoulder 126 provided on both the side toward the filtration screen assembly 104 and the side toward the apertures 102, the square shoulder 126 can be provided on only one side of the orifice 122.
- the inner sidewall surface 128 of the orifices 122 extending from shoulder 126 to shoulder 126 (i.e., edge to edge), is shown cylindrical and parallel to the longitudinal axis of the restrictor tube 118, but can be other configurations. Additionally, the annular protrusion that defines the orifice 122 is short.
- the length of annular protrusion along the longitudinal axis of the restrictor tube 118 can be less the largest transverse inner dimension of the tube 118 and/or orifice 122 (e.g., diameter, if is cylindrical).
- the axial length of the annular protrusion is approximately equal to or less than half the largest transverse inner dimension of the orifice 122.
- the axial length of the annular protrusion is less than half, and in some instances less than one third, the largest transverse inner dimension of the tube 1 18.
- the flow reduction is achieved with multiple orifices 122, rather than a single orifice.
- FIG. 2 shows three orifices 122 in each restrictor tube 118.
- some or all of the restrictor tubes 118 can have a different number of flow orifices 122.
- some or all of the restrictor tubes 118 can be provided without internal orifices 122.
- the orifices 122 of a given tube 118 can be of the same or different configuration. For example, all can have the same flow area and/or the same maximum transverse dimension (e.g., diameter, if the orifices are cylindrical) or some can have different flow areas and/or maximum transverse dimensions. All can have the same axial length or some can have different axial lengths. All can have the same configuration of square/not-square edges and/or shoulders and some can have different configurations of edges and/or shoulders.
- the configuration of the restrictor tubes 118 and/or mix of different configurations of restrictor tubes 118 can be tailored to achieve specified flow properties, such as pressure drop and/or flow rate drop, through the flow control device. Further, having removably attached restrictor tubes 118 allows interchanging the restrictor tubes 118 to initially configure and reconfigure a previously configured flow control device 110 to set or change the flow properties. Additionally, some or all of the different flow properties, such as pressure drop and/or flow rate drop, through the flow control device.
- restrictor tubes 118 can be configured to fit in some or all of the different configurations of flow restrictor housing 112 and ring 116.
- one can manufacture and stock a broad array of different lengths, inner diameters, number and configuration of restrictor tubes 118.
- a smaller number of flow restrictor housings 112 and rings 116 and/or partially assembled flow control devices 110 lacking the restrictor tubes 118 can then be manufactured and/or stocked, for example, corresponding to each size of base pipe 100. Then, when one or more flow control devices 110 are needed for a well, the appropriate restrictor tubes 118 to achieve specified flow properties for the particular well can be added.
- Such modularity can save on manufacturing and inventory expense.
