초록 ▼

In a well containing a multi-phase fluid flow regime is disposed an elongated body member with a funnel configuration attached thereto for the purpose of collecting and mixing the multiple fluid phases. An aperture is provided in the body member, proximate to the apex of the funnel configuration, to allow dicharge of the substantially homogeneous mixture of the fluid phases from the funnel through a passage in the body member. A rotor is acted upon by the flow of this mixture and generates a signal representative of the mixture flow rate. A portion of the mixture then enters a chamber in the elongated body member wherein a measurement is made of the degree of penetration of the mixture achieved by gamma radiation, thereby yielding a measurement representative of the density of the mixture. The flow rates and volumetric fractions of each of the individual phases may then be determined in accordance with the mixture density and total flow rate.

대표청구항 ▼

A method of measuring the flow rates of the individual phases of a fluid flow regime having at least two phases, comprising the steps of: mixing at least a portion of the flow to produce a mixture of substantially uniform composition; measuring the density of said mixture of substantially uniform composition; determining the volumetric fraction of each phase of said mixture of substantially uniform composition at least in accordance with the measured mixture density; measuring the flow rate of said mixture of substantially uniform composition; and determining the flow rate of each phase of the flow regime, said flow rate of each phase determined by; determining a correction term to account at least for the effect of slippage between the phases of said fluid flow regime in accordance with the measured density of the individual phases of said flow regime; and measuring the flow rates of the phases of said flow regime at least in accordance with the measured flow rate of said mixture, each phase\s volumetric fraction of said mixture and the correction term accounting for at least the effect of slippage between the phases.
