Flow Monitoring Tool

摘要

A system for measuring conditions in a wellbore includes tubing extending into the wellbore. A first fiber optic cable extends axially along a first surface portion of the tubing and has at least one signal generation gauge located at a predetermined location for producing a generated acoustic signal that propagates outward from the generation gauge and through the tubing. A second fiber optic cable extends axially along a second surface portion of the tubing and is operable to receive a resulting signal of the generated acoustic signal so that wellbore parameters proximate to the predetermined location can be determined. The second fiber optic cable is spaced apart from the first fiber optic cable and is operable to transmit data of the resulting signal to a receiver.

1. A system for measuring conditions in a wellbore, the system comprising:
tubing extending into the wellbore; a first fiber optic cable extending axially along a first surface portion of the tubing and having at least one signal generation gauge located at a predetermined location for producing a generated acoustic signal that propagates outward from the at least one signal generation gauge and through the tubing; and a second fiber optic cable extending axially along a second surface portion of the tubing and operable to receive a resulting signal of the generated acoustic signal so that wellbore parameters proximate to the predetermined location can be determined, the second fiber optic cable being spaced apart from the first fiber optic cable and being operable to transmit data of the resulting signal to a receiver.
