Abstract

A flow control device is provided that in one embodiment includes a flow-through region configured to receive formation fluid at an inflow region and discharge the received fluid at an outflow region and a setting device configured to adjust the flow of the fluid through the flow-through region to a selected level. The setting device includes a coupling member configured to be coupled to an external latching device adapted to move the coupling member to cause the setting device to alter the flow of the fluid from the flow-through region to the selected level.

Claims

1. An apparatus for use downhole, comprising:

a flow control device including a flow-through region configured to receive fluid at a first flow region and discharge the received fluid at a second flow region, the flow-through region forming a plurality of independent channels, wherein each channel has a flow path in an axial direction with unique flow properties relative to other channels and wherein the fluid flows through only one of the plurality of independent channels at a time;

a setting device configured to adjust the flow of the fluid through the flow-through region to a selected level, the setting device including a coupling member configured to be coupled to a latching device adapted to move the coupling member to cause the setting device to alter the flow of the fluid from the flow-through region to the selected level.

2. The apparatus of claim 1, wherein the flow-through region includes a plurality of channels, each channel defining a different flow rate through the flow-through region.

3. The apparatus of claim 1, wherein the selected level corresponds to:

(i) one of a plurality of flow paths defined by the plurality of independent channels; and

(ii) a flow area of the flow-through region selected by the setting device.

4. The apparatus of claim 1, wherein the flow-through region provides a pressure drop across the flow control device utilizing one of:

an orifice;

a helical path;

a flow path configured to induce turbulence based on water or gas content in the fluid.

5. The apparatus of claim 1, wherein the setting device includes a guide sleeve having a guide track and a pin that moves in the guide track to rotate the guide sleeve to select the desired level of the flow of the fluid through the flow control device.

6. The apparatus of claim 5, wherein moving the coupling member along a first direction causes the pin to move in the guide track to move the guide sleeve along a second direction.

7. The apparatus of claim 6, wherein the setting device further includes a biasing member configured to move the guide sleeve opposite the first direction.

8. The apparatus of claim 7, wherein the biasing member is a spring.

9. The apparatus of claim 1, wherein the coupling member is a mechanical member accessible from inside a tubular member associated with the setting device.

10. An apparatus for use downhole, comprising:

a flow control device including a flow-through region configured to receive fluid from an uphole source and discharge the received fluid to a formation, the flow-through region forming a plurality of independent channels, wherein each channel has a flow path in an axial direction with unique flow properties relative to other channels and wherein the fluid flows through only one of the plurality of independent channels at a time;

a setting device configured to adjust flow of the fluid through the flow control device, the setting device including a coupling member; and

a latching device configured to move in the setting device and couple to the coupling member to operate the setting device to adjust the flow of the fluid through the flow control device.

11. The apparatus of claim 10, wherein each independent channel provides a pressure drop to the fluid flowing therethrough.

12. The apparatus of claim 11, wherein the setting device is further configured to allow flow of the fluid from one of the independent channels.

13. The apparatus of claim 10, wherein the setting device includes an indexed member that adjusts the flow of the fluid through the inflow control device.

14. The apparatus of claim 10, wherein the setting device includes a rotatable member configured to be rotated to adjust the flow of the fluid from the inflow control device.

15. The apparatus of claim 14, wherein a linear motion of the rotatable member causes rotation of the rotatable member.

16. The apparatus of claim 15, wherein the setting device includes a biasing member configured to apply force on the rotatable member.

17. The apparatus of claim 10, wherein:

the coupling member is accessible from inside a tubular member associated with the setting device; and

the latching member is configured to couple to the coupling member from inside the tubular.

18. The apparatus of claim 10, wherein the coupling member is a magnetic element and the latching member includes a magnet configured to magnetically couple to the coupling member from inside the setting device to adjust the flow of the fluid from the inflow control device.

19. A method, comprising:

providing an flow control device having a flow-through region configured to receive formation fluid at an inflow region and discharge the received fluid at an outflow region, the flow-through region forming a plurality of independent channels, wherein each channel has a flow path in an axial direction with unique flow properties relative to other channels and wherein the fluid flows through only one of the plurality of independent channels at a time; and

coupling a setting device to the flow control device, configured to adjust the flow of the fluid through the flow-through region to a selected level, the setting device including a coupling member configured to be coupled to an external latching device adapted to move the coupling member to cause the setting device to alter the flow of the fluid from the flow-through region to the selected level.

20. The method of claim 19, wherein each of the plurality of channels defines a different flow rate through the flow-through region.
