METHOD AND INSTALLATION FOR FLOW RATE MEASUREMENT OF PRODUCTS FROM GAS-CONDENSATE AND OIL WELLS Russian patent published in 2014 - IPC E21B47/10 G01F15/08 

FIELD: oil and gas industry.

SUBSTANCE: group of inventions is related to oil and gas producing industry and may be used for current accounting of flow rate measurement of gas-condensate and oil well in real time mode. The unit for flow rate measurement of oil wells comprises a hydrocyclone separator with condensate collector. Liquid pipeline connected to a condensate collector and gas pipeline connected to a hydrocyclone separator. A liquid flow meter installed at the liquid pipeline, a gas meter installed in the gas pipeline. The unit is equipped with at least one sampler in the gas pipeline and additional separation unit capable to determine condensate content in gas. Gas-liquid mixture is supplied continuously to the hydrocyclone separator with the condensate collector; the mixture is separated continuously into liquid and gas in the hydrocyclone separator. Gas and liquid are supplied to the gas and liquid pipeline with gas and flow meters, gas and liquid flow rates are defined by the flow meters, at that gas sample is taken from the gas pipeline by the sampler. Condensate in the gas sample is analysed by additional separating installation and the product flow rates are determined considering condensate content in gas against the data of additional separation unit.

EFFECT: ensuring on-line and accurate measurement of quantity of separated liquid, associated gas and gas condensate and potential determination of their composition.
