摘　　要：天然气井口的产出总是伴随着液态烃、游离水和压缩蒸汽,未经脱水脱烃处理,含有少量凝析油、凝析水、饱和水蒸气,持液率较高的天然气称之为湿天然气或多相天然气。这样的油污、水蒸汽与硫化物等杂质易粘附腐蚀流量计传感器,同时输气管线内有一定积液,杂质和积液影响着普通流量仪表计量特性。毕托巴流量计采用由点到面的测速原理,其开放式的取压孔结构和V字型的斜面能够有效地防堵。中海油BZ19-6-WHPA平台很早应用毕托巴流量计,通过数据对比,毕托巴气流量计湿天然气现场测量数据稳定准确,满足生产工艺要求,毕托巴湿天然气流量计科学准确的计量数据为用户能源管理控制提供有效技术保障。The output of natural gas wellhead is always accompanied by liquid hydrocarbon,free water and compressed steam.Without dehydration and hydrocarbonation treatment,natural gas containing a small amount of condensate,condensate water and saturated steam with high liquid holdup is called wet natural gas or multiphase natural gas.Such impurities as oil,steam and sulfide are easy to adhere and corrode the flowmeter sensor,and there is a certain amount of liquid accumulation in the gas transmission pipeline,Impurities and liquid accumulation affect the metering characteristics of ordinary flowmeters.BiTOBAR flowmeter adopts the velocity measurement principle from point to surface,and its open pressure hole structure and V-shaped inclined plane can effectively prevent blocking.BZ19-6-WHPA platform of China National Offshore Oil Corporation has used BiTOBAR flowmeter for a long time.Through data comparison,the on-site measurement data of wet natural gas of BiTOBAR gas flowmeter is stable and accurate,which meets the requirements of production process.The scientific and accurate measurement data of BiTOBAR wet natural gas flowmeter provides effective technical guarantee for users’energy management and control.
