EXPERIMENTAL INSTALLATION FOR IMITATION OF GAS-LIQUID MIXTURE AND DYNAMIC PROCESSES IN THE STOCK OF THE GAS WELL Russian patent published in 2018 - IPC E21B47/00 G01M99/00 

FIELD: gas industry.

SUBSTANCE: invention relates to devices intended for conducting scientific and applied research in the field of development and operation of gas and gas condensate fields, carrying out experiments related to simulation of dynamic processes occurring in a gas or gas condensate well working with sand and / or liquids, including interacting with the surface-active foaming substances and other non-corrosive chemicals. Experimental setup for simulating the motion of a gas-liquid mixture and dynamic processes in a gas wellbore contains the main and inner columns of transparent tubes, a backflow column, a system for supplying and regulating gas flow, a thermostatically controlled system for supplying and regulating the flow of water and an imitator of oil, a system for supplying and regulating the flow of reagent, a hydraulic system for reusing water and hydrocarbon fluid. Main column in the upper part is connected to a return flow column, the outlet of which is connected to a separator equipped with liquid and gas outlets. Installation is equipped with instrumentation, video and photo recording devices. Main column of pipes and the return flow column are fixed to the mast. In order to allow the reagent to be fed into the annulus, a capillary tube is introduced, with the possibility of changing the position along the entire length of the main tube string.

EFFECT: technical result is to expand the functionality of the installation and increase operational safety and reliability.
