METHOD FOR MEASURING FLOW RATE OF OIL WELLS Russian patent published in 2019 - IPC E21B47/10 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil industry, in particular, to method of extracting parameters of operation of underground production wells, and can be used in information and measuring systems of mine development of oil for control of oil production process at mine method of extraction of high-viscosity oil. Method of measuring flow rate of oil wells involves installation of shutoff valves at the wellhead, installation of sensors to control temperature of underground wells at the mouths of underground wells with possibility of monitoring their parameters in a long time interval. At that, shutoff valves at the wellhead are equipped with drain devices providing drainage of wells. In addition to sensors for monitoring temperature meters are additionally installed flow meters, pressure sensors, thermomanometers, wherein installation of measuring instruments is carried out on automated devices for well drainage, as well as on devices preventing heat carrier outlet into mine workings. Information obtained from sensors is analyzed, while obtaining information can be carried out automatically in an online mode and periodically by an operator for oil and gas production in a given time interval, then, using data of measuring instruments and devices for drainage of underground wells and devices preventing heat carrier outlet into mine openings, control and control zones of thermal action over thickness and area of formation.

EFFECT: high accuracy of measurement data of the process and longer time interval for obtaining said data for enhancing control and control over the oil production process.
