DEVICE FOR THERMODYNAMIC STUDIES OF PROPERTIES AND PHASE BEHAVIOUR OF FORMATION FLUIDS IN FORMATION CONDITIONS Russian patent published in 2024 - IPC G01N7/14 G01N25/02 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil and gas industry and is intended for studying physical properties of formation fluids using PVT analysis. Disclosed is a device for thermodynamic studies of properties and phase behaviour of formation fluids in formation conditions, which comprises cell housing (26) with a mandrel, piston (20), sealing elements (2, 6, 23), a mixing device arranged with the possibility of mixing the sample inside cell housing (26), pressure sensor (7) and a temperature sensor located with the possibility of measuring parameters of the sample inside cell housing (26), inlet (9) and outlet (10) valves, measuring device arranged with possibility of piston position determination, piston mechanical drive, electric heater (11), cooling device (12), cell housing inclination system and control unit with computer software. Device is additionally equipped with a temperature sensor, inlet and outlet valves, a mandrel, a hold-down nut, a mechanical piston drive, a casing, an electric heater, a cooling device, a cell housing inclination system and a control unit with computer software.

EFFECT: improving reliability, quality and accuracy of sample measurements, for example, a sample of formation fluid in the form of gas condensate.
