STAND FOR STUDYING THE PROCESS OF FORMATION OF ASPHALT-RESIN AND PARAFFIN DEPOSITS Russian patent published in 2023 - IPC G01N11/08 

FIELD: hydrodynamics.

SUBSTANCE: invention is related to specialized testing equipment in the field of fluid hydrodynamics, namely to devices for studying the formation of paraffin deposits during the operation of oil wells and the transportation of waxy oil. The stand includes a supply tank with a cone-shaped bottom, equipped with a breathing valve, a temperature sensor, pressure sensors, a flow meter, a pump, a measuring section, a circulation thermostat, and a personal computer. The container for the investigated liquid is fixed on an annular support, which is installed in the tank for the heat carrier of the water bath, which is made in the form of a hollow cylinder. On top of the container for the test liquid, a cover is installed with the possibility of removal, in which holes are made, in which a mechanical stirrer, a breathing valve and a cable are installed with the possibility of removal, which connects the submersible temperature sensor to the microcontroller. A hole is made in the lower part of the tank for the water bath coolant, into which a heating element is installed with the possibility of removal, an immersion temperature sensor is placed inside the tank, which is connected via a cable to the microcontroller, a tee is installed on the test liquid supply line, to the first outlet of which the drain line is connected via shut-off valves with the possibility of removal, to the second outlet of which the circulation pump unit, the check valve and the first cross are connected in series with the possibility of removal, the first outlet of the cross is connected with the possibility of removal through the shut-off valves to the drain line, the second outlet of the drain line is connected to the gas supply line through the shut-off valves and the compressor, and the third outlet is connected to the test liquid supply line, on which a flow meter, a valve, shut-off valves are installed in series with the possibility of removal, to the shut-off valves the second cross is connected with the possibility of removal, to the first and the second outlets of the second cross temperature and pressure sensors are connected with the possibility of removal, and to the third outlet the measuring section is connected through the adapter, to which, through the adapter , the third cross is connected with the possibility of removal, to the first and second outlets of which temperature and pressure sensors are connected with the possibility of removal, and to the third outlet, the viewing segment of the piping and shutoff valves on the return line of the test liquid are connected, the return line passes through the upper part of the tank for the heat carrier of the water bath and is connected through the outlet to the container for the test liquid. The measuring section includes a measuring section coaxially and tightly fixed to the outer pipe of the measuring section with the possibility of removal through an adapter, the cooling liquid line is connected through adapters to both ends of the outer pipe of the measuring section, and a temperature sensor, a circulation thermostat and a temperature sensor are installed in series on the cooling liquid line.

EFFECT: determination of factors affecting the intensity of deposit formation in wells and pipelines.
