Abstract

A downhole measurement system may comprise an optional fluid inlet section configured to accommodate fluid flow between a well and a zone surrounding the well. The system may further comprise a flow conditioning section configured to receive the fluid from the fluid inlet section. The flow conditioning section may be configured to produce a substantially homogenized fluid flow. In addition, a measuring section may be provided and configured to measure at least a portion of the fluid flow from the flow conditioning section. The measuring section characterizes a parameter of the fluid flow. In other embodiments, there may be a method for characterizing a parameter of a fluid flow comprising the steps of directing the fluid flow to a flow conditioning section. Other steps may be conditioning the fluid flow to a substantially homogeneous state and measuring a parameter for at least a portion of the fluid flow.

Claims (46)

1. A system for completing one or more zones of a well, wherein each of the zones comprises:

a zone sectioning device comprising at least one packer;

a flow conditioning section configured to produce a substantially macroscopically homogenous fluid flow;

a measuring section configured to measure a least a portion of the fluid flow from the conditioning section;

a inflow control device configured to provide access between an interior of a well tubing and a reservoir; and

a shroud configured to direct the fluid flow to the inflow control device;

wherein the measuring section characterizes a parameter of the fluid flow.

2. The system recited in claim 1 wherein the zone sectioning device comprises two packers.

3. The system recited in claim 1 , wherein the measuring section is configured to characterize two or more parameters of the fluid flow.

4. The system recited in claim 1 , wherein the parameter of the fluid flow is at least one of mass flow rate, volume flow rate, speed of flow, temperature, viscosity, density, water cut, or pressure.

5. The system recited in claim 1 , wherein the conditioning section comprises a labyrinth flow path.

6. The system recited in claim 1 , wherein the measuring section samples substantially all of the fluid flow.

7. A method for characterizing a parameter of a fluid flow comprising:

directing the fluid flow to a flow conditioning section;

conditioning the fluid flow to a substantially homogenized state;

measuring the parameter for at least a portion of the fluid flow; and

directing the fluid flow, with a shroud, to an inflow control device configured to provide access between an interior of a well tubing and a reservoir;

wherein the measured parameter is used to characterize the fluid flow; and

wherein the fluid flow and the flow conditioning section are disposed in a downhole zone of a well.

8. The method recited in claim 7 , wherein the parameter is measured for substantially all of the fluid flow.

9. The method recited in claim 7 , wherein a labyrinth flow path is provided for conditioning the fluid flow.

10. The method recited in claim 7 , further comprising communicating the measured parameter to another location.

11. A system for completing one or more zones of a well, wherein each of the zones comprises:

a zone sectioning device comprising at least one packer;

a flow conditioning section configured to produce a substantially macroscopically homogenous fluid flow;

a measuring section configured to measure a least a portion of the fluid flow from the conditioning section;

a inflow control device configured to provide access between an interior of a well tubing and a reservoir; and

a fluid inlet section configured to direct the fluid flow into the flow conditioning section;

wherein the fluid inlet section is further coupled to a packer used to inhibit the fluid flow from flowing past an external circumference of the fluid inlet section;

wherein the measuring section characterizes a parameter of the fluid flow.

12. The system recited in claim 11 , wherein the zone sectioning device comprises two packers.

13. The system recited in claim 11 , further comprising a shroud directing the fluid flow to the inflow control device.

14. The system recited in claim 11 , wherein the measuring section is configured to characterize two or more parameters of the fluid flow.

15. The system recited in claim 11 , wherein the parameter of the fluid flow is at least one of mass flow rate, volume flow rate, speed of flow, temperature, viscosity, density, water cut, or pressure.

16. The system recited in claim 11 , wherein the conditioning section comprises a labyrinth flow path.

17. The system recited in claim 11 , wherein the measuring section samples substantially all of the fluid flow.

18. A method for characterizing a parameter of a fluid flow comprising:

directing the fluid flow, through a fluid inlet section, to a flow conditioning section;

conditioning the fluid flow to a substantially homogenized state; and

measuring the parameter for at least a portion of the fluid flow;

wherein the measured parameter is used to characterize the fluid flow;

wherein the fluid flow and the flow conditioning section are disposed in a downhole zone of a well; and

wherein the fluid inlet section is further coupled to a packer used to inhibit the fluid flow from flowing past an external circumference of the fluid inlet section.

19. The method recited in claim 18 , wherein the parameter is measured for substantially all of the fluid flow.

20. The method recited in claim 18 , wherein a labyrinth flow path is provided for conditioning the fluid flow.

21. The method recited in claim 18 , further comprising communicating the measured parameter to another location.
