METHOD AND DEVICE FOR STUDYING THE MOVEMENT OF GAS-LIQUID MIXTURES IN WELLS, AS WELL AS FLOWLINES AND PIPELINES FROM WELLS Russian patent published in 2023 - IPC E21B47/10 E21C39/00 

FIELD: oil and gas industry.

SUBSTANCE: operation of gas, gas condensate and oil wells. A stand for studying the movement of gas-liquid mixtures in wells, as well as flowlines and pipelines from wells, consists of an experimental string, divided into sections using profile elements, a casing, a device for introducing an experimental mixture into the string and removing it from it, a separator, a supply and control unit for liquid flow rate, gas flow supply and control unit, gas-liquid mixture temperature control and adjustment unit, coolant temperature control and adjustment unit, gas and liquid flow meters, gas supply pipeline to the experimental string, liquid supply pipeline to the string, gas circulation devices, filter element, a block for monitoring and adjusting the set pressure in the device, pressure sensors at the inlet and outlet of the experimental string, a pipe for draining liquid from the stand, shutoff equipment, a pipeline for supplying liquid to the stand, as well as pressure and temperature sensors for measuring pressure losses along the length of the experimental string.

EFFECT: method for studying the movement of gas-liquid mixtures in wells, as well as flowlines and pipelines from wells, consists in that the experimental string is set in the required position, the required gas and liquid flow rates are set, the gas-liquid flow is injected into the experimental string, the gas-liquid mixture is circulated in a closed cycle, control the characteristics of the gas-liquid mixture and maintain them at a given level, change the pressure and temperature along the experimental string and at the end of the specified period of time evaluate the pressure loss in the experimental string as the difference between the pressure values at the inlet and outlet of the experimental string.
