METHOD AND DEVICE FOR MEASURING MULTIPHASIC FLOWS, PARTICULARLY IN HYDROCARBON WELLS

摘要

The invention relates to a method and a device for measuring the flow of a multiphase fluid formed from a continuous phase and from a dispersed phase composed of bubbles. According to the invention, a local sensor having a dimension in the direction of flow which is substantially smaller than that of the bubbles is used to generate a signal having different levels according to the phase in contact with the sensor, the transitions between levels containing information relating to the flow parameters.
