Claims
- 1. A tubing for use in a well bore capable of furnishing a well fluid, the tubing comprising:
an annular member having a passageway; and at least one port connected to detect a composition of the well fluid and control flow of the well fluid into the passageway based on the composition.
- 2. The tubing of claim 1, wherein the port comprises:
a valve positioned to control the flow of the well fluid into the passageway; a sensor for detecting the composition; and a controller responsive to the sensor and connected to operate the valve.
- 3. The tubing of claim 2, wherein the annular member comprises:
an outer layer having at least one opening for receiving the well fluid; and an inner layer forming an annular space between the outer layer and the inner layer, the inner layer having an opening to the passageway, and wherein the valve controls the flow of well fluid through the opening of the inner layer.
- 4. The tubing of claim 1, wherein the port includes a material responsive to a predetermined composition, and wherein the material is positioned to alter the flow of the well fluid based on the presence of the predetermined composition.
- 5. The tubing of claim 4, wherein the annular member comprises:
an outer layer having at least one opening for receiving the well fluid; and an inner layer forming an annular space between the outer layer and the inner layer, the inner layer having an opening to the passageway, and wherein the material controls the flow of well fluid through the opening of the inner layer.
- 6. A method for use in a well bore capable of furnishing a well fluid, the method comprising:
detecting a composition of the well fluid; and automatically, controlling flow of the well fluid into a passageway of a tubing based on the composition.
- 7. The method of claim 6,
wherein the detecting includes using a sensor, and wherein the controlling includes using a valve to control the flow of the well fluid into the passageway and using a controller responsive to the sensor to operate the valve.
- 8. The method of claim 6 wherein the detecting includes:
receiving the well fluid in an annular space in the tubing.
- 9. The method of claim 6,
wherein the detecting includes using a material responsive to a predetermined composition, and wherein the controlling includes using the material to alter the flow of the well fluid based on the presence of the predetermined composition.
