| 摘要 | A wet gas flow measuring method, wherein measuring total flow differential pressure value ”P of wet gas in a pipeline by a differential pressure flow measuring device (201), measuring section gas contents of the wet gas in the pipeline by at least two phase fraction meters respectively (202), obtaining optimized section gas content value GVF opt by a flow calculating module based on the section gas contents respectively measured by the at least two phase fraction meters (203); and calculating gas volume flow rate Q g and liquid volume flow rate Q l by the flow calculating module based on the total flow differential pressure value ”P of the wet gas and the optimized section gas content value GVF opt (204). As the section gas content of the wet gas in the pipeline is detected by the redundant phase fraction meters, the gas volume flow rate Q g and the liquid volume flow rate Q l can be measured accurately, which meets the requirements on production measurements of oil and gas field and facilitates management improvement and production optimization of oil-gas reservoir. A wet gas flow measuring apparatus is also provided. | ||||||
