Water Volume Fraction of Flowing Fluids

摘要

A measurement tool having one or more measurement cells disposed in a fluid flow path is provided. Measurements are made in each of the measurement cells and a fluid type is identified based on the outcome of the measurements. A numerical value is associated with each measurement cell based on the identified fluid type, and a total fractional volume of the identified fluids is determined using the associated numerical values. There may be a relatively large number of measurement cells distributed so as to substantially cover the cross-sectional area of the flow path, relatively few measurement cells distributed randomly in fixed locations in the flow path, or a single measurement cell moveably located in the flow path. The measurement cells measure a property such as resistivity, capacitance, dielectric constant, or electrical impedance. The total fractional volumes of the identified fluids may be determined using a statistic.

1. A method, comprising:
providing a measurement tool having one or more measurement cells disposed in a fluid flow path; making one or more measurements in each of the one or more measurement cells; identifying a fluid type for each measurement cell based on the outcome of the one or more measurements; associating with each measurement cell a numerical value based on the identified fluid type; and determining a total fractional volume of at least one of the identified fluids using the associated numerical values.
