MULTIPHASE FLOWMETER FOR THE COMPONENT-BY-COMPONENT DETERMINATION OF THE FLOW RATES OF GAS, HYDROCARBON CONDENSATE AND WATER IN THE PRODUCTS OF GAS CONDENSATE WELLS Russian patent published in 2021 - IPC G01F1/74 

FIELD: measuring tech.

SUBSTANCE: invention relates to the field of measuring technology and can be used in gas wells or areas of primary gas processing. The multiphase flowmeter consists of a restriction device, measuring and reference resonators of the decimeter range, a filter that beats off the liquid phase, a gas volume meter that has passed through the filter, temperature and pressure control devices in the measuring and reference resonator, electrically controlled valves, electronic blocks - a flowmeter operation control unit and a block for processing information and calculating component costs. The restriction device is made in the form of a Venturi tube, on which the pressure drop ΔP is measured, which makes it possible to determine the gas-liquid flow rate. The density of the gas-liquid flow is measured by the frequency shift of the measuring resonator covering the throat of the Venturi tube.

EFFECT: operational determination of natural gas, hydrocarbon condensate and water consumption without preliminary separation of well production products into these components.
