UNIT FOR MEASUREMENT OF FLOW RATE OF OIL AND GAS WELLS (VERSIONS) Russian patent published in 2015 - IPC E21B47/10 

FIELD: measurement equipment.

SUBSTANCE: invention relates to oil and gas industry and can be used for measurement of flow rate of production of oil and gas wells. An unit for measurement of flow rate of oil and gas wells includes at least one system for measurement of flow rates of oil, water and gas, which is hydraulically connected by means of pipelines to an inlet line of the unit, which is connected to oil wells, and to the outlet of the header, which is made in the form of a piece of a pipeline with ascending and descending segments. On the descending segment there installed is a multiphase Coriolis flow meter and at least one parametric sensor. A flow homogenisation device is installed in the pipeline in front of the descending segment. A pipeline connecting the measurement system of flow rates of oil, water and gas to the inlet line of the unit, at the inlet of this system, can be also provided with at least one ascending segment and one descending segment, which are located in series. With that, the system inlet is connected to the outlet of the descending segment of the pipeline.

EFFECT: improvement of measurement accuracy of a phase flow rate in a real time mode due to homogeneity of the measured flow of a gas-liquid mixture.
