The application of wet gas flow meter at shale gas wellhead is of great significance to reduce the investment and operation cost of shale gas extraction. The flow conditions at the wellhead of shale gas and the technical measuring principles of the current wet gas flow meters are briefly analyzed in this paper. A wet gas flow meter was tested on the wet gas flow test facility, and the performance of the wet gas flow meter with the correlation model developed with the air and water as test medium is studied, which is helpful to optimize the wet gas metering process design of shale gas wellhead and to improve the wet gas metering technology. The research shows that the measurement principle of the current wet gas flow meters are workable, however, the wet gas correlations of the wet gas flow meter must be calibrated with wet natural gas according to the working conditions.
