- (1)
- According to the calibration results in pure gas, pure water and pure oil, it can be seen that the fiber probe can accurately identify the gas, the resistance probe can accurately identify the water, and both of them have low identification accuracy for oil. Based on this response relationship, the combination of an optical fiber probe and a resistance probe can realize an accurate identification of oil, gas and water, to determine whether the fluid at the probe is gas, water, or oil.

- Through the data analysis and verification of gas–water and oil–water two-phase flow, the AORT instrument can accurately identify and distinguish oil, gas and water. Due to the small number of probes, there is a certain error in the measurement of holdup. Through comparative analysis with the data of RAT and CAT, it was determined to be better to use a combination of AORT and RAT for gas–water two-phase flow; while a combination of AORT and CAT is preferred for oil–water two-phase flow. Through the current experimental analysis, the advantages and disadvantages of the AORT instrument were found. According to the analysis of the experimental results, the combination of instruments were superior for use in the oil–water and gas–water two phase flow, providing a reference for subsequent instrument improvement and experiments.
