Abstract

The utility model relates to an oil-water-gas three-phase flow metering device, which makes a gas-liquid separating jug, a gas-liquid controlling jug, a fluid flow meter, an oil-gas-water compositional instruction, a gas metering instrument and a gas-liquid dashpot connected through a flange and a pipe line to form an oil-water-gas phase-splitting gage ductwork. The upper portion of the gas-liquid separating jug is connected with a gas-liquid admitting port, the upper portion and lower portion of the gas-liquid separating jug are separately connected with the upper portion and lower portion of the gas-liquid controlling jug through a gas discharging pipe and a liquid discharging pipe. The gas-liquid controlling jug is arranged with a float adjusting valve inside, a gas outlet pipe on the upper portion, and a liquid outlet pipe on the lower portion, wherein, the gas discharging pipe and the liquid discharging pipe are connected with the gas-liquid outlet pipe at the gas-liquid collecting pipe. The inner and outer portion of the whole device have no auxiliary electric control system, thereby the utility model has small volume, light weight, simple structure, steady and reliable extended service and small pressure loss. The utility model is suitable for the gas-liquid automatic phase-splitting on-line measuring of any flow pattern, in particular to measuring the multi-phase flow which has intermittent liquid and bigger gas-liquid change. The measuring accuracy can amount to +-0.5-2%, the phase-splitting flow measuring is steady, the measuring accuracy is not influenced by the flow type of gas and liquid and the liquid condition, thereby the dielectric viscosity range is wide (thin oil, heavy oil and the like).
本实用新型涉及一种油、水、气三相流流量计量装置,通过法兰与管线将气液分离罐、气液控制罐、液体流量计、油气水组分仪、气体计量仪、气液缓冲罐连接组成油水气分相计量管网。气液分离罐上部与气液进口管相连,气液分离罐上部和下部分别通过排气管和排液管与气液控制罐的上部和下部相连;气液控制罐内置有浮球调节阀,罐体上部设有气体出口管,下部设有液体出口管,其中排气管与排液管在气液汇流管处与气液出口管相连。本实用新型体积小、重量轻、结构简单:整个装置内外部无辅助电控系统,长期运行稳定可靠,且压力损失小;它适用于任何流型的气液自动分相在线计量、尤其是间歇来液、气液变化比较大的多相流量测量,且测量精度可达到±0.5~2%,分相液量测量平稳,计量精度不受气液流型和流体状态影响,适用介质粘度范围宽(稀油、重油等)。
