摘要： An apparatus and method for estimating a parameter of a fluid flowing in a tubular is disclosed. A source of a primary magnetic field is coupled to the tubular and is configured to induce the primary magnetic field in the fluid to align nuclei of the fluid in the tubular along the primary magnetic field. A transmitter transmits an excitation signal into the fluid. A receiver detects a signal from the aligned nuclei responsive to the excitation signal. A processor estimates the parameter of the fluid from the detected signal. The source of the primary magnetic field is removable from the tubular. A coil may induce a secondary magnetic field to either enhance the strength of the primary magnetic field in the tubular or substantially cancel the primary magnetic field in the tubular, for example, to reduce particle build-up in the tubular.

摘要： A method and apparatus for estimating a flow rate of a phase of a multiphase fluid is disclosed. A first velocity distribution is obtained for a first set of nuclei in the fluid from a Nuclear Magnetic Resonance (NMR) signal received for the fluid in response to a first NMR excitation signal. A second velocity distribution is obtained for a second set of nuclei in the fluid from an NMR signal received for the fluid in response to a second NMR excitation signal. A velocity of the phase is estimated from the first velocity distribution and the second velocity distribution. The flow rate of the phase is estimated using the estimated velocity of the phase and an estimated volume fraction of the phase.

摘要： Multi-phase flow is estimated in a flow meter by measuring fluid pressure within the flow meter and using the measured pressure to calculate a density of the flow. A total flow rate through the flow meter is estimated based on the calculated density and a PVT analysis of the fluid. A corrected total mass flow rate is calculated using a liquid/gas slip correction technique. Fluid flow rates are further corrected with a discharge coefficient that varies with changes in the Reynolds number of the fluid. The gas and oil fractions can be determined from the corrected total mass flow rate and gas fraction.

A magnetic field is induced in the fluid to align nuclei of the fluid along a direction of the magnetic field. A radio frequency signal is transmitted into the fluid from a transmitter to excite silicon nuclei present in the fluid. A signal is received from the silicon nuclei responsive to the transmitted radio frequency signal at a receiver.

摘要： Multi-phase flow is estimated in a flow meter having a first and a second stage by empirically deriving an algorithm for the water and gas fractions, measuring pressures within the flow meter, and estimating a total mass flow rate based on the measured pressures. A corrected total mass flow rate is calculated using a liquid/gas slip correction technique. The oil fraction can be determined from the corrected total mass flow rate and gas and water fractions.
