FLOW REGIME RECOGNITION FOR FLOW MODEL ADAPTATION

摘要

A sensor of a multiphase flow meter is operated to determine a physical property attributable to multiphase fluid flow in a conduit of the multiphase flow meter. A stationarity of the multiphase fluid flow is determined based on the determined physical property in actual conditions compared to expected noise of the sensor in stationary flow conditions. A flow model variable is selected from a plurality of flow model variables based on a gas content of the multiphase fluid flow and the determined stationarity. The multiphase fluid flow is then modeled by adjusting the selected flow model variable.
