STAND FOR PHYSICAL SIMULATION OF THE PROCESS OF WATER RELIEF Russian patent published in 2022 - IPC G09B23/40 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the field of drilling oil and gas wells and can be used to test working pairs of hydraulic downhole motors. Distinctive features of the stand for physical modeling of the process of liquidation of water ingress are that the chamber is made of external and internal sleeves, which are concentrically mounted on a support; a cover is installed on top of the tank and chamber, in which holes are made, in which a pipe and inlet pipelines with variable hydraulic resistance are installed, which are made in the form of a distribution manifold, a drilling fluid supply line and a brine supply line, in the upper part of the tanks with drilling fluid and with brine holes are made in which the outlet of the drilling fluid supply line and the outlet of the brine supply line are installed, while level gauges and needle valves are installed in the tanks, a pressure switch, a pressure gauge, a check valve, a valve are installed in series on the drilling fluid and brine supply lines, and from the distribution a safety line with a valve is installed from the manifold to the pump, outlet pipelines are fixed on the support, made in the form of drilling fluid drain and brine drain lines, at the ends of which filters are installed, a container with a stapler is fixed on the frame, which is connected to the pipe through the stapler supply line to the pump.

EFFECT: modeling the process of elimination of brine manifestation at various values of well and reservoir pressure, ensuring the reliability of the system and reducing the risk of failure of individual components of the installation.
