Field performance evaluation of wet gas flowmeter in shale gas wellhead

ObjectiveA typical shale gas production platform was selected, and a self-designed two-phase flowmeter experimental device prizing was used to evaluate the field performance of the wet gas flowmeter under different production conditions. MethodsThe characteristics of wet flow measurement in shale gas wellhead are analyzed, and the performance characteristics of wet flowmeter in shale gas wellhead under different gas-liquid flow rates are investigated. ResultsWithin the tested flow range, the deviation of gas flow metering result is between -6.07% and 0.82%, and the deviation of liquid flow metering result is between -24.91% and 96.49%. As the flow rate of gas-liquid two phase flow deceases, the measurement error of wet gas flowmeter increases gradually. ConclusionsThe measurement performance of wet gas flowmeter is closely related to gas-liquid flow and other working conditions, so it is necessary to further expand the scale and scope of the experiment, and formulate clear technical requirements indicators of wet gas flowmeter as soon as possible to ensure that the applied wet gas flowmeter can meet the demand of shale gas exploitation.
