DISTRIBUTED SYSTEM AND METHOD FOR MEASURING FLOW RATES OF MULTIPHASE AND/OR MULTICOMPONENT FLUIDS EXTRACTED FROM OIL AND GAS WELLS Russian patent published in 2021 - IPC E21B43/12 E21B47/00 E21B47/10 

FIELD: oil and gas industry.

SUBSTANCE: group of inventions relates to the extraction of multiphase and/or multicomponent fluids from oil and gas wells and is intended for measuring the flow rates of phases and/or components of extracted fluids. A distributed flow rates measurement system for multiphase and/or multicomponent fluids extracted from oil and gas wells contains measuring devices, computing modules and a single data processing device located in at least two wells, designed to collect and process measurement results from all measuring devices and ensure the creation, updating and distribution of predictive models to measuring devices, as well as optimization of the entire system. In this case, each of the measuring devices is installed on the flow line of the fluid extracted from the well and is a set of sensors sensitive to at least one physical parameter of the flow extracted from the well of a multiphase and/or multicomponent fluid. Each of the computing modules is installed on the flow line of the extracted fluid, connected to a measuring device installed on this line at least for collecting, processing and transmitting measurement results. In accordance with the measurement method, continuous measurements of the parameters of the flow of the extracted fluid are carried out by means of measuring devices. For each well, the values of the flow rates of the phases and/or components of the extracted fluid are determined by predictive models based on the dependencies previously established between the parameters of the flow of the extracted fluid and the values of the flow rates of the phases and/or components of the extracted fluid. The measurement results of all measuring devices and the determination of the flow rates of the phases and/or components of the extracted fluid are transmitted to a single data processing device, and all the transmitted results are stored and processed through a single data processing device.

EFFECT: invention makes it possible to ensure the possibility of using the results of flow rates measurements obtained by one or more measuring devices to create and update predictive models, as well as to optimize the operation of the entire system by scheduling training and monitoring the need for equipment maintenance.
