STAND FOR TESTING OF DOWNHOLE EQUIPMENT FILLED WITH GASEOUS HYDROCARBON BY EXTERNAL HYDRAULIC PRESSURE AT HIGH TEMPERATURES Russian patent published in 2017 - IPC G01M3/02 

FIELD: testing equipment.

SUBSTANCE: stand for testing of downhole equipment filled with gaseous hydrocarbon by external hydraulic pressure at high temperatures contains a housing with an internal cavity hermetically sealed with cover. Downhole equipment is installed in the internal cavity. The internal cavity is able to connect to a hydraulic pressure generation system and is able to connect to a liquid discharge line. The body is equipped with a heater covering the inner cavity. In this case, the downhole equipment on one side is connected to the upper part of the pressure vessel inner chamber, and on the other hand it is able to connect to the gas discharge line. The upper part of the inner chamber has the possibility of alternate connecting to a hydrocarbon gas supply system and an inert gas supply system. The lower part of the inner chamber has the possibility of connecting to a pressure boost system. The inner chamber on the boundary between the upper part and the lower part has the possibility of being connected to the discharge line of the liquid.

EFFECT: external hydraulic pressure testing of downhole equipment filled with a high pressure hydrocarbon gas at high temperatures.
