Multi-well oil and gas metering device is particularly designed for using in oilfields where oil and gas pipeline network is complex. The aim of the device is to improve the process of oil and gas gathering and transmission on the basis of conventional metering device. This oil and gas metering device is capable of metering fluids from multiple wells, greatly reducing production consumptions and decreasing production cost. Through combining the principle of cyclonic separation and gravity separation, and equipping with single-phase meter, the multi-well oil and gas metering device significantly improves separation efficiency and measurement precision while ensures the reliability and stability of the device.
