| Abstract: | Both pressure and differential pressure signals were measured for oil-gas-water multiphase flow in wide ranges of flow parameters in horizootal pipe. The signals' features were extracted and analyzed, which included time domain features, frequency domain features, scale domain features and fractal features. On the bases of the feature analysis, the online recognition of flow regimes was proposed which was a fusion method combining the regulations of flow regimes and the pattern recognition. The proposed method was examined in the oil-gas-water loop and results showed that bubble flow. stratified flow, intermittent flow and annular flow could be identified with more than 90% accuracy. |
