摘 要：Background Understanding the volume fraction of water-oil-gas three-phase flow is of significant importance in oil and gas *** The current research attempts to indicate the ability of adaptive network-based fuzzy inference system(ANFIS)to forecast the volume fractions in a water-oil-gas three-phase flow *** The current investigation devotes to measure the volume fractions in the stratified three-phase flow,on the basis of a dual-energy metering system consisting of the 152Eu and 137Cs and one NaI detector using *** summation of volume fractions is equal to 100%and is also a constant,and this is enough for the ANFIS just to forecast two volume *** the paper,three ANFIS models are *** first network is applied to forecast the oil and water volume *** next to forecast the water and gas volume fractions,and the last to forecast the gas and oil volume *** the next step,ANFIS networks are trained based on numerical simulation data from MCNP-X *** The accuracy of the nets is evaluated through the calculation of average testing *** average errors are then *** model in which predictions has the most consistency with the numerical simulation results is selected as the most accurate predictor *** on the results,the best ANFIS net forecasts the water and gas volume fractions with the mean error of less than 0.8%.Conclusion The proposed methodology indicates that ANFIS can precisely forecast the volume fractions in a water-oil-gas three-phase flow system.
