Method of determining the composition of a multiphase fluid |
摘要 |
A method of determining the composition of a multiphase fluid, such as a flowing petroleum effluent, an emulsion of water and oil, or a foam of oil and gas is disclosed. A first part comprises determining a model expressing the attenuation and the phase shift of a microwave beam as a function of the volume fractions and the permittivities of the various phases. Then, a second part comprises determining the volume fractions of the various phases that make up a multiphase fluid by minimizing the distance between the measured attenuation and phase shift pair and the attenuation and phase shift pair given by the previously determined model.
