For the accuracy of two-phase separation metering, under the condition that the metering instrument technology is mature, the metering accuracy mainly depends on the gas-liquid separation effect, and the more thorough the gas-liquid separation, the higher the gas-liquid metering accuracy. The most common way of metering at present is to meter the oil using a metering separator.
The oil metering of the metering separator usually adopts a horizontal or vertical two-phase separator to carry out oil well yield metering, and because the weight and the volume of the vertical separator are very large, the diameter and the height of the separator used in a common metering station are both more than 0.8m and more than 2.4m, the metering separator is not convenient to transport and install on site, and wellhead metering is not easy to realize. The GLCC (Gas-Liquid Cyclone-Cylindrical Gas-Liquid Cyclone separator) is a vertical installation pipe without any moving parts and internal devices, can realize full separation of two phases and can realize accurate Gas-Liquid metering.
If the GLCC-cyclone separator is used alone to match with a flowmeter to carry out oil well metering, the defects of large volume and heavy weight of the metering separator are overcome. However, because of the limitation of the characteristics of the GLCC-cyclone separator, the diameter is small, and the liquid level control is difficult, the GLCC-cyclone separator has high requirements on the viscosity of crude oil, and has the problems of incomplete separation and poor metering precision.
