SYSTEM AND METHOD FOR MEASURING THE PARAMETERS OF THE FLOW OF A MULTIPHASE AND/OR MULTICOMPONENT FLUID EXTRACTED FROM A PETROLEUM AND GAS BOREHOLE WITH CONTROLLED CHANGE THEREIN Russian patent published in 2022 - IPC E21B47/10 

FIELD: measuring equipment.

SUBSTANCE: group of inventions relates to production of multiphase and/or multicomponent fluids from petroleum and gas boreholes and is intended for measuring the main parameters of the flow of the produced fluid in operating conditions during production. The system comprises at least one main measuring apparatus installed on the flow line of the fluid produced from the well and intended for measuring the parameters of the flow of the produced fluid, an apparatus for changing the parameters of the flow of the produced fluid, connected to the flow line of the produced fluid, and at least one additional measuring apparatus connected to the flow line of the produced fluid and intended for measuring the changed parameters of the flow of the produced fluid.

EFFECT: possibility of varying the main parameters of the flow of the produced fluid in a relatively short time is provided, allowing for an increase in the ranges of change in said parameters for improving the quality of operation of various measuring apparatuses both in and outside of the borehole, and models, evaluation and adaptation of said systems to conditions potentially encountered in the future.
