摘要： The embodiments of the present application disclose a method and an apparatus for determining flow rates of components of multiphase fluid. The method comprises: performing a first magnetization treatment and a second magnetization treatment on multiphase fluid in a pipeline in a target oil and gas well, respectively, to obtain first magnetized multiphase fluid and second magnetized multiphase fluid; determining a first echo train signal set and a second echo train signal set corresponding to the first magnetized multiphase fluid and the second magnetized multiphase fluid, respectively; determining contents of an oil phase component, a water phase component, and a gas phase component of the multiphase fluid at a specified horizon position, and determining a flow velocity of the multiphase fluid at the specified horizon position; and determining flow rates of the oil phase component, the water phase component and the gas phase component in the multiphase fluid. The technical solutions provided by the embodiments of the present application can improve the accuracy of the determined flow rate of each component of the multiphase fluid.
