Multi-component fluid determination in a well bore

摘要

A fluid measurement system and method for determining component mixtures flowing in a conduit such as an oil well. The system includes a sensor wire 24 for location in a well bore 12; a signal generator 22 or 26 for injecting a high frequency signal along the wire; a data acquisition unit to record first reflected signals received from the wire; a system criteria unit to maintain a data set relevant to the system, and a processor unit operable to act upon the first reflected signals and the data set to establish an output indicative of component fluid within the well bore from which the mixture of fluids flowing within the well bore can be determined. An iterative process can be used with waveguide and probabilistic models. Also the signal generator can be operable to apply a second high frequency signal to the member to determine the mixture of fluids flowing within the well bore.
