Based on the theory of acoustic resonance spectroscopy (ARS), the measurement system of the ARS is established for gas content detection in the liquid mixed with a gas. The resonance amplitude (RA) and resonance frequency (RF) are studied with various gas flow rate in a cylindrical resonance cavity. The experimental results show that: the RF and the RA decrease with an exponent attenuation trend with the increase of gas flow rate passing through the cavity, and the attenuation rate of the RA is faster than that of the RF, although both of them are affected by the gas flow rate. Furthermore, the analytical expression for the RF is derived in a cylindrical cavity with a homogeneous flow model, and the curve of the RF with gas flow rate is numerically calculated. The results show that, the RF decreases with the increase of gas holdup. The attenuation rate of the RF is fast when the gas holdup is small. The theoretical and experimental results show that the ARS method could be used in gas detection in a gas-liquid medium, which paves a way for gas rate detection in a gas-liquid flow in a production well.
