摘要： Methods and apparatus determine phase fractions for phases within a fluid mixture flow under a wide range of flow conditions including wet-gas flow. Appropriate flow algorithms can utilize this phase fraction information with a total flow rate of the mixture to find individual flow rates for phases, such as oil, water, and gas or gas and liquid, which can represent a combination of oil and water phases. For some embodiments, a multiphase flowmeter includes an array of spatially distributed pressure sensors configured to determine a velocity of the mixture flow and hence the total flow rate, which is applied with information from a differential pressure meter to calculate the bulk density of the fluid mixture. Further, additional speed of sound information or a water-in-liquid ratio as may be determined by spectral analysis can enable differentiation between the oil and water phases.

摘要： Methods and apparatus for determining phase fractions (relative concentrations) within a multiphase fluid mixture, in the presence of an injected hydrate inhibitor. Combining this phase fraction information with a hydrate inhibitor injection rate (HIIR) enables resolving oil and water flow rates for the phase fractions. The liquid flow rates and a total combined flow rate of the fluid mixture—determined based on a differential pressure of the fluid mixture through a given area—enable resolving a gas flow rate.

摘要： Methods and apparatus enable monitoring a hydrocarbon well for water within a flow stream of the well. A water detector includes a light source for emitting into a flow stream infrared light that includes a water absorbent wavelength band. A detector detects attenuation of the water absorbent wavelength band upon the infrared radiation passing through at least a portion of the flow stream. The water detector outputs a presence of water and/or a phase fraction or quantification of water as determined based on the attenuation. Detecting attenuation of a substantially transmissive wavelength band with respect to water simultaneously with detection of the attenuation of the water absorbent wavelength band can enable correction for non-wavelength dependent attenuation.

摘要： Methods and apparatus for measuring a phase fraction of a flow stream are disclosed. An infrared phase fraction meter includes a light source for emitting into a flow stream infrared radiation that includes first and second wavelength bands. The first wavelength band substantially transmits through first and second phases of the flow stream and is substantially absorbed by a third phase. In contrast, the second wavelength band is substantially absorbed by the second phase relative to the first and third phases. One or more detectors simultaneously detect attenuation of the first and second wavelength bands upon the infrared radiation passing through at least a portion of the flow stream, and a phase fraction of the second phase is determined based on the attenuation. As an example, the first, second and third phases are gas, water and oil, respectively, produced from a well.
