Background
The domestic oilfield single well gas and liquid metering modes are various, and can be mainly divided into two types according to the metering modes: one is a two-phase mixed phase metering, the other is a two-phase separated metering, which is higher in terms of accuracy. For the accuracy of two-phase separation metering, under the condition that the metering instrument technology is mature, the accuracy of metering mainly depends on the gas-liquid separation effect, and the more thorough the gas-liquid separation is, the higher the gas-liquid metering accuracy is. The most common metering method is to meter the separator oil.
The oil yield of the oil well is measured by a horizontal or vertical two-phase separator, and the diameter of the separator used in a common measuring station is more than 0.8m and the height of the separator is more than 2.4m because the weight and the volume of the vertical separator are large, so that the oil well is inconvenient to transport and install on site, and wellhead measurement is difficult to realize. The GLCC (Gas-Liquid Cylindrical Cyclone-cylindrical Gas-liquid cyclone separator) is a vertical installation tube, has no moving parts and internal devices, can realize full separation of two phases, and can realize accurate measurement of Gas and liquid.
If the GLCC-cyclone separator is used alone to measure oil well in combination with the flowmeter, the disadvantage that the measuring separator is large and heavy is overcome. However, because the GLCC-cyclone separator is limited by 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.
