High-efficiency multi-tube-bundle separation metering device based on GLCC

The utility model relates to the technical field of oil field single well metering, in particular to a high-efficiency multi-tube-bundle separation metering device based on GLCC, which comprises a two-stage separator, a mass flowmeter and an intelligent precession flowmeter, a lower outlet of the two-stage separator is fixedly communicated with a liquid outlet pipeline, and an upper outlet of thetwo-stage separator is fixedly communicated with a gas phase communicating pipe. A liquid-phase separation cylinder is arranged on the left side of the two-stage separator, more than one gas-phase tube bundle is fixedly communicated between the gas-phase separation elbow and the gas-phase collection tube, and a first liquid-phase balance tube and a second liquid-phase balance tube are sequentiallyand fixedly communicated between the liquid-phase communication tube and the gas-phase collection tube from left to right. The single-well three-phase metering device is reasonable and compact in structure, convenient to use,
